Ensure economic growth to improve quality of life

Published

By Lacille de Silva

Sri Lankans, since the 1970s, have not been fortunate to have visionary leaders. They were misfits. Their laws are unjust and unacceptable. Their measures are always cruel and inhumane. They do not respect the Constitution and other laws. History proves that if the leaders desire comforts, love power and prestige they are unable to deliver lasting happiness to the nation.

After ending the brutal war, we were reborn. Why did Lankan rulers fail to achieve economic progress there onwards? They too lacked integrity, vision and accountability. They were narrow-minded and acquisitive. The ensuing culture they created is a toxic process. Power has become addictive to them. Why should probity, ethics and good governance apply for both elected and appointed personnel engaged in the service to the citizens?

Nowhere else in the world do senior cabinet ministers doze off in Parliament in the government benches in the front row. It was particularly important, since it happened, while the Head of State was delivering the policy statement as well, in Parliament at its first meeting, after a parliamentary election. It is true that the President runs the government with the support of the Cabinet Ministers. Such ministers therefore do not challenge the poor behaviour of others. This reflects the actual status of affairs of the government.

They have misused legitimate authority given to them to their advantage. Such sordid rulers have collectively subverted laws and the key state institutions such as Parliament, the judiciary etc., for decades. They cannot comprehend that good administration in every area of the government is vital to keep the people happy and their good name.

Our Constitution (Article 12 (1) stipulates that “All persons are equal before the law and are entitled to the equal protection of the law”. The famous proverb tells “When the righteous are in authority, the people rejoice, but when the wicked bear the rule, the people mourn”. We should be happy the Constitution takes great pains to ensure justice for all. And to protect everybody from misrule by double-dealer type big-time operators.

They have destroyed the opposition in Parliament. A strong opposition is vital for running a healthy democracy. Such destructive leaders craftily extended beyond their self-interests to biasedly build a motivated and inspired team of acolytes. They are also equally bellicose and self-centred.

At the time we became independent, we had the second-highest per capita income in Asia, excellent literacy rates, improved healthcare, strong economy etc. Sri Lanka now ranks almost at the bottom in global comparisons.

The most venerable Ajahn Brahm, who is the Chief Monk of the Bodhinyana Buddhist Monastery in Perth Australia had said that “the oldest multinational corporation in the world is the Buddhist Sangha”. According to him, Buddhism has been a positive inspiration for many world leaders. He had said that British Statesman and wartime Prime Minister was one of them. He had also quoted Buddha and said: “Good virtuous leaders lead by example”.

Ajahn Brahm had said in a keynote address to the United Nations in 2007 – “The ideal form of governance is that leaders should embrace self-sacrifice and not self-interest. Leaders should lead without any concern for material reward. Their only reward would be in the happiness of service”. He had also quoted what President John F. Kennedy had said to inspire children and adults and to show the importance of civic action and public service – “Ask not what your country can do for you – ask what you can do for the country”. Sadly, Lankan politicians think differently.

It is the assertion that rulers are constituted by the people for the common good. Our leaders should pledge to commit themselves to refrain from abusing their public positions at the expense of the people, to honestly address the vice of corruption. They should, thereafter, concentrate on how to create a better country for future generations. If they are determined to fulfil their constitutional obligations responsibly and strive hard to win and sustain public trust, it is nothing impossible. They should have the strength of character to correct their wrong-doing.

Government is a trust and the officers of the government, both elected and appointed are trustees. They are entrusted with the powers to make decisions for the benefit of the people. The question of representative roles was conceived by Burke (1968), who argued that representatives should serve as trustees of the interests of those elected them – “virtual representatives”- rather than serving as delegates. If so, how did corruption swallow up the whole country to the detriment of the countrymen? It is the main obstacle to achieve good governance and sustainable development.

They have collectively inflicted misery on every citizen. They are only keen in the pursuit of their prosperity. They are subject to manipulations from superpowers as well. And by crooked godfathers behind ostensible governments. It is a flawed system. The extravagant leaders have only favoured immediate gratifications. It had motivated public officials and even the citizens. Everybody now goes for easy money instead of productive activities.

Entitlements such as infrastructure, education, health care, etc have been curtailed to the citizens. Water, electricity etc are overcharged. The citizens pay bribes to get their legitimate services. Corruption undermines good governance, democracy, and the country’s competitiveness and revenue base.

They use various strategies to gain power. Idi Amin in Uganda won the hearts of the people by expelling British and attacking Western Imperialism. In the 1970s, Sri Lankan leaders criticised the Soulbury Constitution. They had campaigned that the plantations owned by the British should be nationalised. A home-grown Constitution was the only remedy to develop the country according to them.

JRJ did the same thing in 1977. It is a serious flaw in their characters. Nobody wants to correct the shortcomings. This, therefore, is an imbecile system. It does not take you forward. Corruption has become the modus operandi of kleptocrats. It benefits only a handful. It lowers and destroys the quality of lives of millions of others. Nevertheless, we cannot expect every leader to possess the wisdom of Lincoln or Mandela’s large-heartedness. But the need of the hour is true statesmanship.

We need leaders who will chase behind to achieve common goals. We have to ensure a ‘fair go for all’ without any further delay. This could only be done by achieving the SDGs that cut across and integrate economic, social, and environmental dimensions of development, which incorporate the 5Ps (People, Prosperity, Planet, Peace, and Partnerships).

This requires a collaborative and effective response at an unprecedented scale from all traditional and non-traditional actors. If so, we have to change the way we operate at present. We must be more systematic and catalytic.

Forty-two per cent of our population live on less than two dollars a day. Poverty is a punishment for those penniless people. They are paying for others’ sins. Numerous businesses, including professionals too practising privately, tend to hide and not to disclose their actual income, to avoid taxation.

As a result, the income generated by many businesses, professionals etc exists outside the official economy. This has paved the way for the existence of a rapidly growing parallel black money economy. It has grave and disastrous consequences.

The watchdog institutions that should scrutinize government performance need to be further strengthened. The Auditor-General must be given surcharge powers. The Yahapalana government withdrew ‘surcharge power provision’ at the final hour. Special Anti Corruption bodies such as CIABOC should also be permitted to go after powerful politicians. We expect the President to strengthen ethical values to re-create a well-performing bureaucracy.

Why is corruption cancerous? It has the ability rapidly and insidiously to infiltrate and destroy the organs of the state. It had strengthened – bad leadership, politics of the belly, greed and selfishness, clientelism, patronage, nepotism, weak institutions, lack of accountability and transparency, weak ethical values, weak judicial system etc. etc

The destruction caused is inexcusable. They have sold our valuable assets under numerous pretexts. The exploitation is deep-rooted in the bureaucratic and political institutions. The theft of government financial resources too is another serious form of corruption. The government has failed to prioritize its commitment to improving Public Financial Management, which involves a set of responsibilities. The Auditor-General has reported serious shortcomings in revenue management, accounting, monitoring, evaluation areas etc.

Politicians at the national, provincial and local level have become filthy rich overnight. We have heard of instances where customs, inland revenue officers, and many others, pocketing out government revenue with the collision of the payer. We have also heard of ‘ghost workers’ being paid.

Corruption, therefore, thrives in our country. Without ‘political will’ at the highest level nothing can be done to reduce corruption. It fuels injustice, inequality, and deprivation. It also has a disproportionate impact on the most vulnerable. It increases costs and reduces trust in government. It has led to violent extremism and conflict. With its negative effects upon political and economic development, it has serious repercussions on national institutions. Constitutionally, the elected representatives are accountable to people through the Parliament. In reality, it does not happen. It is like a spider web. Only the weak get caught.

The World Bank in a report had highlighted “Corruption and corrupt leaders both deepen poverty and make it difficult for ordinary people to get ahead as a result of their efforts”. It has been proved that it is the biggest obstacle for development. Its consequences are always borne by the most vulnerable sections and particularly the poor.

All that we need is a passionate leader. He should foster the trust and confidence of the people. He should be capable of curbing corruption by promoting ethics and integrity among both elected and appointed officials. He should also be an ardent supporter of good governance. However, on the political side, politicians who have enriched themselves through corrupt practices will not surrender their positions of advantage willingly. We know of donations from foreign sources for election campaigns. which have become a controversial issue as well. Similar donations have been banned in several developed countries. Shouldn’t the government think of such reforms as well?

Why did we forget debt is a double-edged sword? When it has been imprudently used, the results we face currently are disastrous. Excessive debt has impaired the government’s ability to deliver its essential services to its citizens. It is amidst the onset of the Corona pandemic and the deepest economic debacle globally. The Government should not any longer delay the necessary reforms.

By 1960, Korea had borrowed 25 billion dollars internationally for industrialisation. The rulers there had invested all those borrowings prudently. Dollars had worked wonders in Korea. China and other sources granted loans for our leaders. We have recklessly borrowed twice the amount and more, at much higher commercial rates as well. Subsequently, the last government handed over the port of Hambantota to China on a 99-year lease together with 15,000 acres of lands.

President should initiate reforms, restructuring, and rebuilding to improve the quality of lives of our distressed people. Another important issue at hand is the need to expedite matters concerning the large number of corruption cases that had been pushed under the carpet. There have been no significant convictions for graft despite widespread evidence of pervasive corruption.

President should direct the relevant authorities to initiate expeditious legal action regarding the 2015 Central Bank fraud committed allegedly with the help of politicians like Ranil Wickremesinghe. Steps should be thereafter taken to recover stolen assets. All these evidence had been amply revealed at the investigations in the Presidential Commission how RW implanted Arjuna Mahendran, who has recently changed his name to Harjan Alexander. We need the culture of impunity to end and a culture of accountability introduced.

The President should manage the ongoing superpower tensions to the best advantage of the countrymen. And secure our birthright freedoms for all our people. The shocking truth is that the country has been devastated by the two governments that ran governance after ending the war. They have pushed

GOSL to go bankrupt. Our external debt is staggering. Yet, we continue to borrow furthermore externally to repay debts. This is unbelievable. The debt service burden for 2020 exceeds $ 4.8 billion.

This requires that the President engage diplomacy – be highly strategic and tactical, based on pragmatic choices without sacrificing the future of our children any further. Sri Lanka is a textbook case of bad governance. People live in poverty having destroyed everything by incompetent leaders. How do we know whether illicit syndicates too are also linked to a wide range of problems such as law-enforcements, including international criminal interests? Everything possible should be done to give a better deal ASAP.

A new mediation law for smarter dispute resolution of civil and commercial disputes – II

Published

on

(Part I of this article appeared in The Island yesterday.)

An examination of how some of the other countries have institutionalised mediation to address the problem of laws delays shows that an array of institutional devices have been adopted to provide for mediation not only as a voluntary option but also in some jurisdictions, as a mandatory requirement prior to litigation, to respond to serious issues of delays due to congestion in courts.

In the UK , in March 1994, the Lord Chancellor commissioned Lord  Woolf to review the Rules of civil procedure with a view to improving access to Justice, reducing the cost of litigation and removing unnecessary complexity. The resulting  Access to Justice Report (1996) triggered a series of reforms to improve the civil justice system primarily through the civil procedure rules (1999) which articulated that its overriding objective is to enable the court to deal with cases justly and at proportionate cost. In 2023, the Court of Appeal judgment in Churchill v. Merthyr Tydfil County Borough Council [2023] EWCA Civ  1416, decided that English courts do have the power to stay civil proceedings for, or order, parties to engage in mediation or another non-court- based dispute resolution process. The Rules were thereafter amended in 2024 to provide for the use of alternative dispute resolution (ADR) more proactively. These included rules that recognied that –

* promoting  or using ADR is a means of achieving the overriding objective;

*  the court has a duty to actively manage cases to further the overriding objective, including by ‘ordering or encouraging the parties to use, and facilitating the use of, alternative dispute resolution’ and ‘helping the parties to settle the whole or part of the case’

* in deciding a costs order, a court will have regard to all the circumstances of the case, including the conduct of the parties, including whether a party failed to comply with an order for ADR or unreasonably failed to engage in ADR.

An ADR pledge made by the UK Government in 2001 was renewed in 2011, by the Dispute Resolution Commitment (DRC) requiring departments to use mediation, arbitration and conciliation. At that time, the then Justice Minister Jonathan Djanogly said: ‘I believe that government should be leading by example by resolving issues away from court using alternatives which are usually quicker, cheaper and provide better outcomes. We want people to see court as a last resort rather than a first option, and cut down on the amount of unnecessary, expensive, painful and confrontational litigation in our society. In many cases methods like mediation are simply a common sense solution which benefits everyone involved. Although they will not be suitable in every case, they are already saving taxpayers millions every year and can save much more.’

The judicial dicta on the power of the courts to order mediation and the imposition of costs on even a successful party for unreasonable refusal to mediate, provides clear acceptance of a pro mediation approach by the UK courts.

In the USA , the discussion on the need for alternatives was raised in a speech made in 1906, by Roscoe Pound, a relatively unknown legal academic at the time, addressing the annual meeting of the American Bar Association (ABA). The title of his address was “The Causes of Popular Dissatisfaction with the Administration of Justice.”  He critiqued the American legal system and charged that it was riddled with archaic technicalities, too slow, too expensive and adversarial and that there was injustice when  procedure received emphasis above the substantive issues of a conflict. He spoke of the “sporting theory of justice” where litigation was considered as a game where the lawyers were gladiators battling in court to win. He charged that the contentious procedure compels ‘counsel to forget that they are officers of the court and  to deal with the rules of law and procedure exactly as the professional football coach with the rules of the court.’ At the time, Pound’s criticisms were considered scandalous, blasphemous and the ABA refused to publish the speech.  Things changed however.

Thirty years later, Roscoe Pound went on to become Dean of the Harvard Law School and became  a celebrated legal luminary. As for the legal system – Roscoe Pounds sentiments were not dismissed. Seventy years later in 1976, the then Chief Justice Warren Burger convened the Pound Conference (called the second  Pound Conference, with the first attributed to Pounds’ 1906 speech event), to consider whether Pounds’ criticisms had been adequately addressed and what more needed to be done. Professor Frank Sander of the Harvard Law School delivered the keynote address and spoke of his vision for a comprehensive Justice center (the “multi door court house”) where an alternative system would function parallel to the litigation system and disputes would be directed to the most appropriate process, such as arbitration and mediation.

The impact of these discussions resulted in significant changes to the dispute resolution landscape in the USA through statutes, inclusion of ADR in academic courses, and the professionalization of the practice of ADR processes, including mediation. Currently, arbitration and mediation are recognized within the mainstream legal system with resounding success.  All the States have recognized ADR pathways including mediation, in statutes. Mediation is well entrenched in the USA and the success rate is reportedly very high.

Australia has institutionalized mediation through several statutory and other initiatives. Courts are empowered to refer disputes to mediation without the consent of the parties to enable better management of civil matters. The Civil Dispute Resolution Act,  2011 contains provisions to ensure that, other than in respect of certain excluded civil proceedings,  parties must take “genuine steps” to resolve disputes prior to litigation. The Act obligates parties instituting proceedings in court to file a “genuine steps statement” setting out the steps taken to resolve issues or the reasons why no such steps were taken and further provides that a Lawyer acting for such a party must advise that party of the requirement and assist that party to comply with that requirement.

In Ireland, in the very recent case of Burke v O’Connell  [2026] IEHC 314 (May 20, 2026), the High Court considered  whether a court can order parties to mediate a dispute, against their will, or whether a court is restricted to simply inviting the parties to mediate. Among other issues, the court considered whether mandatory court ordered mediation is a breach of a constitutional right of access to courts, and decided that a court delaying court proceedings for court ordered Mediation, even against the will of the parties, would not constitute a breach of the right access to the courts under the Constitution or the European Convention on Human Rights, and that judges in Ireland regularly make clear that the right of access to the courts is not unconditional. Importantly the court observed that the court is not directing the parties to reach an agreement but simply to commence  a mediation.  The Court also observed that a court directed mediation order is a very limited order which does not compel settlement and only requires parties to commence a Mediation process and that while attendance at Mediation may not be voluntary, reaching a settlement is voluntary and made order that a court, in controlling its own process, did have the power to direct Mediation in appropriate cases, and that it was an inherent power of the court to ensure the effective and efficient operation of the courts.

 The Indian Mediation Act, 2023  articulates a pro mediation policy and provides for mediation via a court annexed scheme for which detailed statutory provisions are included. The Act states that parties may voluntarily, and whether there is a mediation agreement or not, take steps to pursue court annexed pre litigation mediation and provides for the steps to be taken therefor (section 5). The Act provides further that, even if such pre litigation mediation is unsuccessful, a court or tribunal may, at any stage of the proceedings, refer parties to undertake mediation and that when a court so refers a dispute, there is no obligation on the parties to come to a settlement (section 7). In respect of high value commercial disputes however,  a plaintiff is required to exhaust ‘the remedy of  pre institution mediation’ prior to instituting action, unless urgent interim relief is sought – section 12A introduced by the Commercial Courts, Commercial Division, and Commercial Appellate Division of High Courts (Amendment) Act, No. 28 of 2018.

 In South Africa, parties are mandated to consider mediation before initiating  litigation in the High Court. Challenged by a serious issue of a severe backlog, with trial dates scheduled even up to 2031, a Directive was issued by the Judge President of the Gauteng Division of the High Court along with a detailed process Protocol, effective April 2025 to require mandatorily that prospective litigants in all civil matters within the Gauteng division must participate meaningfully in a court-annexed mediation process before they can be allocated a trial date. The protocol requires, among other documents, that a Report of the Mediator stating, among other matters, whether parties “participated in good faith” be filed, to obtain a trial date. This requirement has been included to avoid what the Judge President refers to as “sham mediations.”  (https://www.youtube.com/watch?v=v5Gmkzfu8gA&t=425s) Non-compliance results in matters being struck off the roll and could lead to adverse or punitive cost orders. Currently, a challenge to this Directive by the Personal Injury Plaintiff Lawyers Association and the Law Society of South Africa is pending, without a stay of the Rule.

 Singapore has emerged as a global leader in the practice of mediation. The Mediation Act 2017 provides for a framework for the use of mediation and for enforcement of a mediated settlement agreement as a decree  of court. Mediation is well entrenched in the legal system of Singapore and enjoys the support of government as well as the judiciary. Singapore played a key role in UNCITRAL in the deliberations that led to the drafting of the text for the 1998 UN  Mediation Convention and was host to the Convention signing ceremony in August 1999 where a historical number of 46 countries, including Sri Lanka, signed the Convention on the very first day. Many of the training programmes for Sri Lankans that have been arranged by the International ADR Center, have been conducted by the Singapore International Mediation Centre (SIMC) which is renowned for its programmes and for services to handle international commercial disputes.

 The European Union Directive (EU Directive 2008/52/EC) provides that a court may, when appropriate and having regard to all the circumstances of the case, invite parties to use mediation (Article 5.1) and that the Directive is without prejudice to national legislation to making the use of mediation compulsory or subjective to incentives or sanctions … provided that such legislation does not prevent the parties from exercising their right of access to the judicial system (Article 5.2). Many European countries have integrated mediation into their dispute resolution systems through legislation or procedural laws in ways that range from recognizing voluntary reference to mediation to requiring mandatory mediation for specified categories of disputes. Countries such as Italy, Greece, Germany and Belgium are some that have robust systems.

It is clear therefore, that jurisdictions around the world, irrespective of the legal system, have sought to recognize mediation for its value not only for minor community dispute resolution but also for the resolution of high value commercial and other family and civil dispute resolution.  UNCITRALs preparation of the text for the 1988 UN Mediation Convention was inspired by the significant increase in the use of mediation in international trade and the need for a uniform regime for enforcement, such as the UN NY Arbitration Convention provides in respect of arbitration awards.

 Sri Lanka’s advancements have thus far been driven by the private sector. A holistic approach to find responses to the backlog in courts to relieve the pressure on courts, is desired. The promotion  of ADR, including mediation, deserves support from the government as well, since, clearly, laws delays have an adverse impact on the economy of the country and should not be seen only as an access to justice issue. As articulated in the UN Mediation Convention, among the positive beneficial results of using mediation for dispute resolution, is that there are cost savings for the State. It is a means of resolving disputes without detracting from the quality of the resolution.

Killing of Colombo’s ancient trees — a warning on UN’s World Desertification Day – 17 June

Published

on

A fallen tree in Colombo. (File photo courtesy NewsFirst)

In recent years, falling trees have claimed lives, destroyed homes, and sparked an urgent debate: should Colombo’s ancient trees be cut down in the name of safety? But this is the wrong question. The real crisis is not that these trees are dangerous — it is that we have made them so. Through decades of road widening, root-smothering pavements, and indiscriminate branch cutting, we have steadily undermined the very trees we now fear. What we are witnessing is not nature failing us. It is us failing nature. As the world marks World Desertification Day on 17th June, Sri Lanka would do well to reflect that desertification does not begin only in distant, arid lands — it begins whenever a city turns its back on its own green heritage.

In recent years, falling trees have claimed lives, destroyed homes, and sparked an urgent debate: should Colombo’s ancient trees be cut down in the name of safety? But this is the wrong question. The real crisis is not that these trees are dangerous — it is that we have made them so. Through decades of road widening, root-smothering pavements, and indiscriminate branch cutting, we have steadily undermined the very trees we now fear. What we are witnessing is not nature failing us. It is us failing nature.

Colombo, our commercial capital, is considered one of the greenest cities in the world. This is highlighted by the award of the world’s first Wetland City designation to our administrative capital, Sri Jayewardenepura Kotte. Both cities and their green heritage should be treasured and protected — not only as assets of their citizens, but as a matter of national pride.

It is against this backdrop that one must view with deep concern the ongoing destruction of trees and greenery across Sri Lanka, particularly in urban settings such as Colombo and Kotte. The majestic trees lining our traditional tanks, rural areas, and urban areas are part of our heritage. The trees lining Colombo’s Ananda Coomaraswamy Mawatha (previously named the Green Path because of its large trees), Gregory’s Road, Thurstan Road, and Bauddhaloka Mawatha, are over a hundred years old. These are living monuments of our heritage. They provide shade, a natural canopy, and a habitat for a remarkable diversity of bird populations within the city. It is therefore vital that we make every effort to preserve these trees unless they pose a direct danger to human life.

Why Do These Trees Become Dangerous?

To address this question, we must first understand why large trees continue to fall during periods of strong winds. Old photographs indicate that it is we who have widened roads and built pavements to cover the roots of these majestic trees, a true heritage from the past.

A leading reason for trees to fall is age-related decay. Old trees tend to develop weak branches and trunks. Regular inspection of their structural integrity and timely treatment of disease would go a long way in preventing such failures.

The second reason is indiscriminate cutting of branches, which disrupts the natural balance of the tree. A principal offender in this regard is the Ceylon Electricity Board. When interviewing workers engaged in trimming city trees, one consistently hears the same justification: the branch must be cut because it is touching or close to a power line. There are no arborists, trained experts, or senior officials to guide these workers or determine whether a less destructive approach is possible.

The third reason is the destruction of root systems. Across the city, one can observe concrete and paving laid directly over the root zones of large trees. This prevents oxygenation and moisture from reaching the roots, causing them to deteriorate or die. The inevitable consequence is that the tree gradually loses its structural support at the base, making it vulnerable to falling.

What Should Municipalities and Town Councils Do?

To save our ancient trees, we must counter the flawed argument that we need to replace them—these trees are priceless “nature’s investments for hundreds of years” and, as a BBC article on ancient oaks suggests, their genetic heritage is vital for resilient future forests. See “1,000-year-old oaks used to create ‘super forest’ (See )

*  A nationwide strategy is essential: we must start by strengthening the expertise of tree officers in the Colombo Municipal Council and other urban councils to ensure professional health assessments are available, while also linking with botanists, academics, and environmental groups at the University of Colombo.

*  Use Google Maps and GIS for systematic mapping and reviving a citizen science platform, similar to one previously developed by University of Moratuwa, where students and the public can report environmental harm with photos and locations.

*  Technology offers more powerful tools. There are Conventional Visual Tree Risk Assessment (VTRA) methods which fail to detect risks. More advanced methods were reported at the 30 th International Forestry and Environment Symposium 2026 e.g. Ground Penetrating Radar (GPR). These are able to find trunk decay and found examples in urban trees at Viharamahadevi park and Keppetipola road.

*  We can raise public awareness through social media and community events like “tree walks,” a practice which could be further popularized by groups like Ruk Rakaganno (see ) and the Love A Tree Foundation (see )

*  Finally, we must learn from international models like the UK’s Ancient Tree Forum (see ). The latter specialises in protecting trees as a heritage which must be preserved and protected for future generations.

Dengue and its prevention: A global public health challenge

Published

on

Dengue is one of the fastest spreading mosquito-borne viral diseases in the world today, posing a growing threat to nearly half of the global population. The World Health Organization describes dengue as a viral infection transmitted to humans through the bite of infected female mosquitoes, primarily Aedes aegypti and, to a lesser extent, Aedes albopictus. Once considered a disease limited to tropical regions, dengue has now expanded widely across continents, driven by urbanization, climate change, population movement, and weak vector control systems.

The global burden of dengue has increased dramatically over recent decades. According to WHO estimates, there are approximately 100 to 400 million infections annually, although a large proportion remain asymptomatic or undiagnosed. The disease is now endemic in over 100 countries, with Asia bearing the highest share of cases, followed by Latin America and Africa. As transmission intensifies and outbreaks become more frequent, dengue has emerged as a major public health concern requiring coordinated prevention and control strategies.

The nature of dengue infection

Dengue is caused by four closely related viruses known as serotypes: DENV-1, DENV-2, DENV-3, and DENV-4. Infection with one serotype provides lifelong immunity to that specific strain, but only partial and temporary protection against the others. This means a person can be infected up to four times in their lifetime.

Most dengue infections are asymptomatic or mild. When symptoms do occur, they typically appear 4 to 10 days after the bite of an infected mosquito. The clinical presentation includes high fever, severe headache, pain behind the eyes, muscle and joint pain, nausea, vomiting, rash, and fatigue. Because these symptoms resemble other viral infections, dengue is often underdiagnosed in early stages.

While most patients recover within one to two weeks, a small proportion develop severe dengue. This life-threatening condition is characterised by plasma leakage, severe bleeding, organ impairment, and shock. Without timely medical intervention, severe dengue can be fatal. WHO emphasises that early diagnosis and appropriate clinical management can reduce fatality rates to below 1 percent in well-managed settings.

Transmission and mosquito ecology

Dengue is transmitted primarily through the bite of infected female Aedes mosquitoes. These mosquitoes are highly adapted to urban environments and typically breed in artificial water containers found in and around homes. Unlike malaria-transmitting mosquitoes, Aedes mosquitoes bite during the daytime, with peak activity in the early morning and late afternoon.

The lifecycle of the mosquito plays a crucial role in transmission. Eggs can survive for months in dry conditions and hatch when they come into contact with water. Even small collections of water, such as flower pots, discarded containers, tyres, and water storage tanks, can serve as breeding sites.

Urbanisation has significantly contributed to the spread of dengue. Rapid population growth in cities often leads to overcrowding, poor waste management, and inadequate water storage practices, all of which create ideal breeding conditions for mosquitoes. Climate factors such as increased rainfall, humidity, and temperature further enhance mosquito survival and virus replication.

Risk factors and global expansion

Several factors increase the risk of dengue transmission. Population density is a key driver, as densely populated urban areas provide abundant human hosts for mosquitoes. Inadequate housing conditions and poor access to clean water force communities to store water in containers, which often become breeding grounds.

Human mobility also contributes to the spread of the disease, as infected individuals can introduce the virus into new regions where competent mosquito vectors are present. Climate change has expanded the geographical range of Aedes mosquitoes into previously unaffected areas, increasing the risk of outbreaks in both tropical and subtropical regions.

WHO has noted that dengue incidence has increased significantly over the past 50 years, with periodic outbreaks becoming more frequent and severe. The disease is now considered a major global health threat, comparable in burden to other high-impact infectious diseases in many regions.

Clinical management and absence of specific treatment

There is currently no specific antiviral treatment for dengue. Management is supportive and focuses on relieving symptoms and preventing complications. Paracetamol is recommended to reduce fever and pain, while non-steroidal anti-inflammatory drugs such as ibuprofen and aspirin are avoided due to their risk of increasing bleeding.

Patients with severe dengue require hospitalisation for close monitoring and supportive care, including intravenous fluid replacement and management of shock or bleeding. With proper medical care, mortality rates can be significantly reduced.

Early detection is critical. Warning signs such as persistent vomiting, severe abdominal pain, bleeding gums, rapid breathing, and sudden fatigue indicate progression to severe dengue and require immediate medical attention.

Prevention: the cornerstone of dengue control

Since there is no specific cure, prevention remains the most effective strategy against dengue. WHO strongly emphasises integrated vector management as the foundation of dengue control.

Personal protection measures are essential, especially during daytime hours when mosquitoes are most active. These include the use of mosquito repellents containing DEET, picaridin, or IR3535, wearing long-sleeved clothing, and using mosquito nets when resting during the day. Window and door screens also help reduce indoor mosquito exposure.

Environmental management is equally important. Communities are encouraged to eliminate breeding sites by removing stagnant water, disposing of waste properly, and cleaning water storage containers regularly. Even small water collections can sustain mosquito populations, making household-level participation crucial.

Public health programmes also rely on insecticide spraying during outbreaks to rapidly reduce mosquito populations. However, WHO emphasises that chemical control alone is insufficient without sustained community involvement and environmental management.

Community participation and public health response

Community engagement is a central pillar of dengue prevention. Effective control requires continuous participation from households, schools, workplaces, and local authorities. Public awareness campaigns play a vital role in educating populations about mosquito breeding habits and personal protection measures.

Surveillance systems are also essential for early outbreak detection and response. Health authorities monitor dengue cases and mosquito populations to identify high-risk areas and implement targeted interventions.

Integrated approaches that combine environmental management, biological control, chemical interventions, and public education have proven most effective in reducing transmission.

Vaccination and emerging tools

In recent years, dengue vaccines have been developed and introduced in some countries under specific conditions. WHO has recommended the use of certain vaccines in areas with high transmission, particularly for populations with prior exposure to dengue. However, vaccination strategies remain limited and must be carefully implemented due to the complexity of immune responses to dengue infection.

Research continues into new tools such as genetically modified mosquitoes, Wolbachia-infected mosquitoes that reduce virus transmission, and improved diagnostic technologies. These innovations offer promising additional tools but are not yet substitutes for established prevention measures.

Dengue remains a rapidly growing global health challenge with significant medical, social, and economic impacts. Its spread is driven by urbanisation, climate change, and the adaptability of mosquito vectors. While no specific cure exists, timely clinical care can prevent deaths, and effective prevention strategies can significantly reduce transmission.

The World Health Organization emphasises that dengue control depends on a combination of personal protection, environmental management, community participation, and strong public health systems. As the disease continues to expand geographically, sustained global commitment is essential to reduce its burden and protect vulnerable populations.
