Conversation with Prince Phillip on BIA runway and President Premadasa’s genius for getting things done
Excerpted from the memoirs of Chandra Wickremasinghe, Rtd. Addl. Secy to the President
When Emperor Hirohito of Japan passed away at an advanced age, and the Duke of Edinburgh was scheduled to touch down at Katunayaka Airport on his return flight, after attending the funeral. Wije (KHJ Wijeyadasa) wanted me ‘to do the honours’ as he put it, by receiving him after touch down and entertaining him to high tea at the VIP lounge. Accordingly, arrangements were made for myself and British High Commissioner David Gladstone to welcome the Duke and conduct him to the VIP lounge. This was the time when SL had to face the menace of terrorism on two fronts from the JVP and the LTTE and as a precautionary measure there was a tight security wrap provided for the Duke’s safety by crack Air Force troops under the Air Force Commander.
When the plane, which was a small jet, landed, I went up the ramp with HC Gladstone and greeted the Duke who was in the cockpit. After exchanging the usual pleasantries , the Duke said that he had piloted ‘this small thing’ and what he wanted most was to stretch his legs a bit. I told him that we had arranged tea for him in the lounge to which he replied that he would prefer to do a walk up and down the runway to stretch his tired limbs.
I observed that he was dressed in workaday denims. Whilst walking with the Duke in the company of the British HC and the Air Force Commander, along with the security escorts, I engaged him in a conversation enquiring how the funeral was and how the older Japanese people, reacted to their Emperor, who had seen the country through the cataclysmic WW11, passing away. The Duke responded with his characteristic acerbic humour saying ‘ Oh he was dying for a long time and the Japanese had got used to the idea’!
Then about the funeral itself, he said with his typically wry wit, ‘it was a rather long drawn ceremony with a lot of sticks and incense being burnt.’ As the day happened to be cloudy and without any sun I commented that it was not the best of weather we were having that day, to which he replied smiling ‘Oh, ours is infinitely worse.” I also took the opportunity to ask him about the motor vehicle he was supposed to have owned while in Trincomalee where he had served during WW11 as a Sub- Lieutenant in the Royal Navy, adding that there were many here who claimed that they owned the vehicle.
He laughed and said that he too had heard the story of his motor car being owned by a person here adding that as he did not have much money at the time he remembers buying a small Standard or an Austin which was even at that time in a somewhat ‘clapped out condition.’ Soon after his brisk stroll up and down the runway, he opted to board the plane and take off despite our pleas to have tea in the VIP lounge. I must say it was quite an experience meeting the Duke in person and listening to his witticisms which have now become legendary as they are some times mixed with the occasional faux pas, he is notorious for making.
President RP’s way of getting things done on the double
Just one month before he was assassinated by an LTTE suicide cadre, I remember Dayaratna, the President’s Co-ordinating Secretary meeting me and saying that the President wanted to see me. I enquired from Daya, who was a very amiable officer, whether there was a problem; he replied “I do not know, Sir, HE is there alone in the office waiting for you”. When I walked in somewhat apprehensively into his large office room, Daya approached him and said “Sir, Mr. Wickramasinghe is here.”
I remember the President looking at me quickly and saying in Sinhala “Chandra, I have a big problem”. I was taken by surprise when he addressed me by my first name which he had never done before. My immediate reaction was to try to figure out what this big problem was that he as President could not solve. While studying the relevant file, he spoke to me switching onto English this time and said “There are two MPs who are fighting to get an unused paddy store. One of the MP’s wishes to use the store to rehabilitate 32 ex-JVP cadres while the other is keen on converting the store into a vocational training centre to train the youth in the area in vocational skills. This has become a big headache to me”. He then looked at me and said “Here is the file, you examine the problem and summon the MPs and tell them how it should be settled and let me have your report in two days”. I was totally flabbergasted, wondering how I could possibly summon MPs to appear before me and further, to tell them how the matter should be resolved. I had very little sleep that night and remember telling my wife that I regretted ever having joined the Presidential Secretariat.
It was in this despondent mood that I read through the file carefully that night and mapped out a strategy in my mind. I wanted to start working on it the very next morning as the report had to be submitted to HE in two days. I had decided by then in my own mind that the more viable option was the establishment of a vocational training centre which could cater to the needs of the youth in the area. With this in mind, I phoned the Secretary/Ministry of Mahaweli Development (it was either AA Wijetunge or DG Premachandra) and enquired whether land with a perennial water course was available in one of the border areas (Mahaweli H Division). His first reaction was to reply in the negative.
I then told him that HE was keen on settling 32 JVP cadres in a suitable border area. Thinking it was the President who was behind the request, he asked for half an hour to check and get back to me. He rang me within 15 minutes to say that there was a suitable land available with a perennial stream running through it. I then revealed the plan I had in mind for the settlement of the 32 ex-insurgents on this land. I asked him how much of land could be given to each settler to which his reply was that the normal allotment of two and a half acres would be given. I told him ,the extent will have to be five acres, to which proposal he reluctantly agreed, again thinking that this was being suggested at the instance of the President.
On further enquiry by me as to how much money would be given to each allottee to put up a house, he replied that the normal Rs. 5,000/= would be made available. I told him that the amount will have Rs. 20,000/= as we had to take into account the special circumstances. Thinking once again that these were President Premadasa’s instructions, he agreed to give the enhanced amount. I then requested him to send me a blocking plan of the land showing the stream and a report on the extent to be allocated and the amount of money that would be given to build a house, via fax. In the meantime, I made arrangements with Army Headquarters to issue these 32 JVP cadres the necessary firearms (pump guns, they called them) and ammunition and to train them in the use of these weapons. I also remember quipping that as they were JVP cadres such training may be somewhat redundant.
That evening, I telephoned the two MPs to convey to them ‘the decisions made by the President’. The first MP I contacted was the one who wanted to utilize the store for the rehabilitation of the 32 insurgents. I started the conversation asking him whether there was a problem regarding a warehouse in that area. The MP immediately launched on a tirade against the other MP saying that the JVP cadres were after all ‘our own people’ who had to be rehabilitated and reintegrated into society. At this point I told the MP that the President had gone into the issue very carefully and had decided to make the warehouse available for a vocational training centre, as such a training centre would be beneficial to youth in the entire area.
He was naturally taken aback and smelling something fishy, asked me what would happen to the JVP youth to which query I replied that the President had a plan of settling them in System H of the Mahaweli project. The MP immediately countered saying that they would be killed off in no time by the LTTE. I assured him that arrangements will be made to provide suitable firearms to them to defend themselves. He then wanted to know the extent of the allotment that would be given and when I said that each would be given five acres expressed disbelief saying that the normal extent was two and a half acres per settler under the Mahaweli project. I had to reassure him that it would be five acres. When asked about the financial assistance that would be given to build a house and being informed by me that Rs. 20,000 would be given per settler, the MP could not contain his surprise as the usual assistance given for the purpose was Rs. 5,000.
I also assured him that there was a perennial stream running through the land that would provide water for irrigation. At this stage he asked me somewhat testily whose decisions these were and I answered him without demur that they were the President’s. He was silent for a moment before telling me rather forlornly “What’s to be done.” I knew the President wanted me to settle the issue in a reasonable manner and that he would not object to this kind of settlement which ensured that the ex-insurgents who were to be settled in ‘System H’ would be treated exceptionally, providing them much better facilities than what the normal Mahaweli settlers were entitled to, without summarily throwing them to the wolves, so to speak.
I do not think the MP himself was too unhappy when I detailed to him the special concessions and facilities that would be extended to the JVP settlers, deviating from what was laid down. Further, the manner in which the MP somewhat timorously ended the conversation, indicated that he was prepared to accept the arrangement which he thought was based on the President’s instructions. I think what troubled him more was that the other MP was getting what he wanted and that this meant a loss of face for him.
The other MP whom I telephoned thereafter, was jubilant that the President had decided to give the warehouse to him to start a vocational training centre and gave expression to his joy by praising the sagacity of the President in making the correct decision. The next morning I took the file back to the President and explained to him at length what I had done informing him at the same time that I had deviated a little from the normal entitlements of a Mahaweli settler in view of the special circumstances of the case. He only asked me what Secy/Mahaweli had said about the deviations and on my replying that he concurred in them given the special circumstances, seemed satisfied that the additional concessions given were quite in order.
The President however examined my report very carefully, going into all the relevant details including the availability of water etc. Finally, he asked me what the MPs had to say about the decision and on my telling him that they seemed to agree with the new proposals, turned to me and thanked me which was again something he rarely or never did. I cited this particular case to show President Premadasa’s way of managing contending parties posing seemingly intractable problems which virtually defied solution. Being a hard-nosed realist with a decidedly practical orientation in working out solutions to problems, what was uppermost in his scheme of things was to forge a quick practical solution.
This is why officials who worked for him were all the time on tenterhooks trying desperately to work out practical solutions to problems which prima facie, seemed impossible to be solved. What facilitated matters in seeking solutions to such virtually intractable problems was the fact that all concerned officials in Ministries, Departments, State Corporations and Public Authorities at the time, were only too eager to chip in and help. This is what made our work, though trying and oftentimes exasperating , still, most satisfying, when the particular problems were eventually, successfully settled.

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