The Old Town Of Galle And Fortifications
The World Heritage Sites Of Sri Lanka
By EVERYMAN
Volleyball it is claimed is our national sport. However there is no doubt that Cricket is the most popular sport in Sri Lanka .That popular West Indies calypso ‘Cricket, lovely cricket.’,’ will always be ringing in our ears. From the villages where youngsters from around 16 to 26 or maybe even older, use ‘polpithi’ bats, to the towns where more sophisticated young men use willow bats. It is cricket, cricket and more cricket. Little wonder then that we have been correctly described as ‘ a cricket crazy nation.’ And when it comes to grounds for international matches the Galle International Stadium is the most favored by our cricketers, our coaches and our spectators. The reason is that as at today (03. 05 .21), 34 Test Matches were played on these grounds of which Sri Lanka won 19 and lost only eight. In addition to this, in a press release datelined June 8, 2020, Yash Mittal an avid lover of cricket has listed five of the most picturesque cricket grounds in the world. And yes – you have guessed it – the Galle cricket grounds, cradled between the Galle Fort and the Indian Ocean, heads the list !
Galle has an ancient and interesting history. In pre-Christian times Galle, called ‘Gimhathitha’ which is derived from the ancient Sinhala script meaning ‘port near the river Gin’ ( Gin Ganga ) was a major port in our country. As early as 1400 BC cinnamon had been exported and Galle may well have been the main transshipment port in this part of the world, with Persians, Arabs, Greeks, Romans, Malays, Indians and Chinese doing trade. A trilingual Inscription on stone dated February 14, 1409 in Chinese, Tamil and Persian was erected by the Chinese Admiral, Zheng He, to commemorate his visit to Galle. This is now in the Colombo National Museum. A copy can be found in the Maritime Museum in Galle. So dear reader our country’s friendship with China is a centuries old one. Nothing new in that. Galle is also referred to by the famed Muslim Berber-Moroccan scholar and traveler Ibn Batuta, in his well documented book ‘Rihlah’ (Travels ) who visited the island in 1344 CE. He referred to Galle as Quali/ Kali..
No doubt that all these references to the ancient port city of Galle and others as we will read about later on, contributed to UNESCO listing the Old Town of Galle and the Fortifications as a World Heritage Site in 1988. According to an article in the Ceylon Observer datelined November 26, 2017 by Dimuthu Attanayake and Manjula Fernando it is stated that, “The International Council on Monuments and Sites (ICOMOS ) in its advisory body evaluation has recommended Galle Fort under its criterion IV Code. Galle provides an outstanding example of urban ensemble which illustrates the interaction of European architecture and South Asian tradition from the 16th to the 19th centuries. Among these characteristics that makes this an urban group of exceptional value is the original sewer system from the 17th century which is flushed with sea water and controlled by a pumping station formerly activated by a windmill in the Triton Bastian.”
According to the Galle Heritage Foundation the Triton Bastian (which is a projecting part of a fortification) is one of many gun Bastians built on a long rampart. Some having been built by the Portuguese but many by the Dutch. For the Dutch it must be remembered, such fortifications were necessary to defend the western approaches to Galle Fort, from enemy navies. In particular the British navy. In the article referred to above it is also stated that “the most salient feature is the use of European models adapted by local manpower to the geological, climatic, historic and cultural conditions of Sri Lanka. In the structure of these ramparts coral was frequently used along with granite. In the ground layout all the measures of length, width and height conform to the regional metrology. The wide streets were planted with grass and shaded with Suriyas and were lined with houses, each in its own garden and an open verandah supported by columns which is another sign of acculturation of an architecture which is European only in its basic design.” (AUTHOR’S NOTE : Suriyas were trees usually used for fencing and sometimes grew to a height of 30 feet).
Built first by the Portuguese in the 16th Century, Galle reached the height of its development during the Dutch colonial rule. Galle, it has been claimed is the best example of a fortified city in South and South – East Asia and is the last remaining fortress in Asia built by European occupiers. Since it was the Dutch that earned for Galle the honour of being listed as a World Heritage Site, it would be relevant to describe what they actually built. Among the heritage monuments there is the Dutch Reformed Church referred to at that time as ‘Groote Kerk.’ Located at the entrance to the Fort it was built in 1755 and is said to be the oldest Protestant church in Sri Lanka. The floor is paved with large gravestones taken from the old Dutch cemetery. The pulpit is made of calamander wood from Malaysia. This church is still in use.
On Church Road is All Saints Church. This is an Anglican Church built on the site of the former Dutch Courthouse. The Church was consecrated by Bishop Claughton, the second Bishop of Colombo on February 21, 1871. Prior to this the Anglican congregation used to worship in the earlier mentioned Dutch Reformed Church. Today the faithful still gather here for worship. An interesting fact is that a large bell was installed in the dome of the Church in memory of the first Vicar, Rev Dr. Schrader. However for security reasons this bell was lowered in 1960, and now lies in the premises of the Cathedral of Christ the Living Saviour in Colombo.
Along Lighthouse Street is what has been described as a ‘quaint little’ Roman Catholic Church. It was built by the Dutch in 1893 and is claimed to be one of the oldest Roman Catholic Churches in the country where services are held even today. Referring to Churches one cannot overlook another historic landmark, namely the magnificent St Mary’s Cathedral located on Prison Road, in the city of Galle. It was built in 1874, but not by the Dutch. It was by the Society of Jesus. There is no doubt that this too would have contributed to the inscription of World Heritage Site by UNESCO.
Catering to the religious needs of the Buddhist population there lies along Rampart Street the Sri Sudharmalaya Temple which was built as far back as 1889.In the construction of this temple there is evidence of the impact of Dutch and European architecture. And then we come to the beautifully crafted, majestic , Meeran Mosque, built in 1904, it is located opposite the Galle Lighthouse and was and still is a place of deep veneration and prayer for the Muslims who form the largest religious group within the Fort.
Moving from the religious to the secular, there can be seen as one enters the Galle Fort through the Old Gate, the British Coat of Arms, with the inscription ‘ Dieu et Mon Droit (God and My Right). In the inner part of this fortified entrance is a 1668 dated inscription with the letters VOC (Verenigde Oostindinsche Compagnie – meaning Dutch East India Company). Further inside the Fort is the 87 ft. tall, Lighthouse, built by the British in 1939. However the earlier Lighthouse also built by the British in 1848 was destroyed by fire in 1936. Further into the Fort on Church Street was the old Government House. Built in 1683 it was used for administrative purposes and also served as the residence of the Commander. Regrettably however it is now closed, for visitors.
Near the Old Gate was the Great Warehouse built around 1669 which was used to store spices and ship’s equipment. It now houses the National Maritime Museum. One of the oldest buildings within the Fort is the Dutch Hospital built in the 17th Century, referred to as the Old Dutch Hospital, very aptly it is on Hospital Street and close to the harbor for the benefit of Dutch seamen. It was supposed to be built on a location where there was a Portuguese mint. In 1850 the British converted this to a barracks. It is now a shopping and restaurant arcade.
Then on Church Street there is another complex built in 1684 as the headquarters of the Dutch commanders and the staff. In 1865 it was converted to the New Orient Hotel catering to European passengers travelling between Europe and Galle. Today it is the five star Amangalla Hotel. Outside the Galle Fort on the southern side of Galle Bay in an island promontory. On it is Closenberg Hotel. It is a story of the transformation of an elegant manor to a star- class hotel. Once called Villa Marina, it was built in 1859 by Captain Bayley, who was the local agent for the P & O Shipping Company. It changed ownership in 1889 to Simon Perera Abeywardena who was the son-in-law of one of the country’s greatest entrepreneurs and philanthropists, Sir Charles Henry de Soysa. In 1965 this home was reconstructed to be a hotel. It was named Closenberg. The name is derived from the Dutch name Klossenburg, which means a small fort on which the sea roars.
Yet another chapter in the colorful history of Galle began in 1796, when the British East India Company entered Ceylon from India where it had its stronghold. Quite naturally they nudged the Dutch out of Galle. Two large Sri Lankan conglomerates which had in those early years been British companies, had their beginning in Galle. One was Chas. P. Hayley and Company which was established in 1878 and much later became Hayleys PLC. The other was Clarke Spence and Company, which was established in 1868 and much later became Aitken Spence PLC.
From buildings and companies let’s move on to trees. In fact one particular tree – The breadfruit tree ( Artucapus incisisus ). Known in Sinhala as ‘del.’ It was introduced by the Dutch. In an article dated January 10, 2021 titled ‘Historical Ancient Trees in Sri Lanka’ by Hemi it is stated that this was planted by the Dutch. circa 1721. Located near the Akersloot Bastian. It is still in existence.
And then Alas! came the Tsunami on December 26, 2004. At 6.28 that morning a mega under-sea earthquake of 9.3 on the Richter scale erupted near Banda Aceh in Sumatra. This sent 100 ft high waves speeding across the Indian Ocean ferociously lashing Indonesia, Malaysia, Thailand, Sri Lanka, India, Maldives, Myanmar and even Somalia –in that order. By 9.25 the waves smashed into the southern and south-western coast. Amongst the districts affected was Galle. The walls of the rampart which were built to withstand cannon fire now acted to withstand Nature’s fury. They became wave breakers. In addition the effective drainage system installed by the Dutch drained off the flood waters without much damage within the Fort itself.
To quote Fr. Damian Arsakularatne, a highly respected Roman Catholic priest who was the former Director of Caritas which was one of the many organisations that did post- tsunami, reconstruction work ” If the Fort had not been there, Oh my God!, I can’t even imagine the damage that would have been. It saved us.” However the adjacent Galle International Stadium and grounds suffered severe damage. In fact the stadium served as a temporary shelter for hundreds of persons who had lost their homes. In Galle town the old vegetable market built by the British in 1890 was in shambles.
Back to cricket. The Galle Cricket Grounds will hold pleasant memories for Sri Lanka’s greatest cricketer and gentleman. Mutthiah Muralidaran ( that’s how he wishes his name to be spelt ). It was here in 2003 that in the match against England that he weaved his magic spell of spin bowling and claimed seven wickets for 40 runs. But Muralidaran was also a philanthropist. When his Manager, Kushil Gunasekera, who is also a like minded philanthropist and is the Founder – Chief Trustee of the charitable organization called ‘Foundation of Goodness’ (FOG) Muralidaran also became an active Trustee. The vision of this charity was supporting local communities through projects such as catering to children’s needs, education, health care and psycho-social support. After the tsunami this organisation focused on one of the areas most tragically affected by the tsunami.
This was Seenigama located 14 miles North/West from Galle. It was Kushil’s home town. Muralidaran that icon of cricket got a ready response to his call for funds for post tsunami reconstruction work which came pouring in specially from England and Australia.
Let’s revert to the historic cricket grounds. Renovations specially of the Stadium began on May 8, 2006. Out of devastation came development. It became larger, better equipped and more accommodative for cricketers, spectators and the media. On December 17, 2007, it was opened by President Mahinda Rajapasksa . The first test Match played here was against England which ended in a draw. Perhaps we should conclude from where we started. ‘Cricket, lovely cricket.’ After all we are cricket crazy aren’t we ?

United in diversity: Lessons from Erasmus+ for Sri Lanka’s future

Can a scholarship programme help heal a divided society? At first glance, the idea seems ambitious. Yet one of Europe’s most celebrated educational initiatives was created with precisely that aspiration. Long before Erasmus+ became synonymous with international student exchanges, it represented something far more profound: a belief that education could bridge historical divisions, foster mutual understanding and lay the foundations for lasting peace. Nearly four decades later, that vision offers valuable lessons not only for Europe but also for countries like Sri Lanka, where the search for sustainable social cohesion remains unfinished.
Today, Erasmus+ is recognised as the European Union’s flagship programme for education, training, youth and sport. Since its launch in 1987, it has enabled millions of students, academics, educators and young professionals to study, teach, train and collaborate across borders. What began as an exchange programme, involving just 3,200 students from 11 European countries, has grown into one of the world’s largest educational mobility initiatives, benefiting more than nine million participants, while extending partnerships well beyond Europe.
Its success, however, cannot be measured simply by the number of scholarships awarded, or universities connected. To understand why Erasmus+ has become one of Europe’s greatest success stories, one must return to the continent that gave birth to it.
Europe, in the 20th century, was defined as much by division as by cooperation. Two World Wars devastated entire societies, leaving behind fractured economies, broken political relationships and generations shaped by conflict. Countries that now cooperate closely, within the European Union, had once fought devastating wars against one another. Germany itself became the most visible symbol of post-war division, split into East and West as ideological tensions hardened during the Cold War.
Rebuilding roads, industries and institutions was only part of Europe’s challenge. Rebuilding trust proved far more difficult. Political agreements could establish new alliances, but they could not erase decades of suspicion, or guarantee, that future generations would see one another as partners, rather than adversaries.
It was in this context that the idea of European integration steadily gained momentum, during the 1950s. Economic cooperation was recognised as essential for prosperity, but European leaders increasingly understood that lasting unity demanded something deeper. If peace was to endure, citizens, not merely governments, needed opportunities to learn from one another, engage across cultures and develop a shared sense of belonging.
Education emerged as one of the most effective instruments for achieving that vision.
Universities became spaces where young Europeans could encounter perspectives beyond their own national histories. Academic exchange was no longer viewed simply as an educational experience but as an investment in peace itself. Every student who crossed a border carried back more than academic knowledge; they returned with friendships, cultural understanding and a broader appreciation of Europe’s diversity.
Erasmus became one of the most enduring expressions of that philosophy. Rather than treating education as an isolated national endeavour, it positioned learning as a shared European project, capable of strengthening social cohesion, alongside economic development. The classroom, in many respects, became an arena where reconciliation could take root more naturally than through political negotiation alone.
Over the years, that vision expanded significantly. What began as a higher education exchange programme has evolved into Erasmus+, supporting vocational education and training, school education, adult learning, youth initiatives and sport. It facilitates not only student mobility but also research collaboration, professional development, volunteering and institutional partnerships that connect universities, civil society organisations, businesses and public institutions across national boundaries.
The programme’s ambitions extend well beyond academic achievement. At its core lies the conviction that lifelong learning contributes not only to individual advancement but also to stronger, more resilient societies. Education becomes a driver of innovation, economic opportunity, civic participation and social cohesion, creating benefits that extend far beyond university campuses.
Over the years, that vision expanded significantly. What began as a higher education exchange programme has evolved into Erasmus+, supporting vocational education and training, school education, adult learning, youth initiatives and sport. Today it enables millions of learners, educators and institutions to collaborate across national boundaries through academic exchanges, research partnerships, professional training and community engagement.
At its heart, however, Erasmus+ remains guided by a simple idea: that education can be a powerful instrument of social transformation. By encouraging mobility, fostering institutional cooperation and creating opportunities for people from different cultures and backgrounds to learn together, the programme has become one of the European Union’s most enduring investments in social cohesion. Its emphasis on inclusion, multilingualism, democratic values and international partnership reflects a broader understanding that education is about shaping societies as much as it is about educating individuals.
Europe’s experience offers an important insight. Lasting peace cannot rest solely on political agreements, or economic growth. It also depends on creating opportunities for people to meet, learn and build relationships across the boundaries that once divided them.
That insight resonates far beyond Europe. Sri Lanka’s history is different, but the challenge is strikingly familiar. Although we are a single island nation, we remain a society shaped by multiple and often overlapping divisions. Ethnic tensions, linguistic disputes, regional inequalities and uneven access to opportunity have all left lasting marks on the national consciousness. Decades of civil conflict claimed thousands of lives, displaced communities and interrupted generations of economic and social progress. While the guns have long fallen silent, building a genuinely cohesive society remains an unfinished task.
Much of Sri Lanka’s post-war discourse has understandably centred on constitutional reform, political settlements and economic recovery. These remain indispensable. Yet reconciliation cannot be legislated into existence. It must also be experienced. Trust is built through sustained interaction, shared experiences and opportunities for people to encounter one another beyond the identities that have historically separated them. This is where education can become more than a means of acquiring qualifications; it can become a means of rebuilding society itself.
An Erasmus-inspired model offers an important way of thinking about that possibility. Its greatest lesson is not that students should study abroad, but that educational mobility has the power to transform individuals and, over time, societies. When young people leave familiar environments, study alongside peers from different backgrounds and return with new perspectives, they bring back more than degrees. They return with networks, confidence and a greater appreciation of diversity. These are precisely the kinds of social capital that divided societies often struggle to cultivate.
For Sri Lanka, mobility should not be understood only in international terms. It should begin at home. Many young people, particularly those from rural and economically disadvantaged communities, have limited opportunities to study or train outside their immediate surroundings. A national scholarship and exchange programme could enable students from Jaffna to spend a semester in Matara, undergraduates from Monaragala to undertake research in Kandy, or vocational trainees from Batticaloa to work alongside institutions in Colombo. Such exchanges would expose students to different communities, cultures and lived realities within their own country before connecting them with opportunities overseas.
This is not merely an educational investment; it is an investment in social cohesion. Mobility broadens horizons, but it also improves employability by exposing students to new skills, institutions and professional networks. Erasmus+ has consistently demonstrated that graduates with international and intercultural experience are better prepared for an increasingly interconnected labour market. A Sri Lankan model could similarly strengthen both human capital and national integration, ensuring that access to opportunity is determined less by geography than by potential.
The same philosophy applies to institutional partnerships. One of the defining strengths of Erasmus+ lies in its ability to connect universities, schools, vocational institutes, businesses and civil society organisations through collaborative projects. Knowledge is not confined within institutional walls but shared across disciplines, sectors and borders. Sri Lanka’s universities have long produced talented graduates and important research, yet stronger collaboration between higher education institutions, industry, local communities and international partners could generate far greater social and economic impact. Educational cooperation should become a national strategy rather than a collection of isolated initiatives.
Equally significant is the programme’s commitment to inclusion. Sri Lanka’s inequalities are not confined to ethnicity alone. They are also geographical, economic and educational. Access to quality higher education and international opportunities remains uneven, with students from rural districts often facing barriers that extend well beyond academic ability. An Erasmus-inspired initiative would, therefore, need to place inclusion at its centre, ensuring that students from historically underrepresented communities are not merely invited to participate but actively supported to do so. Excellence and equity should not be competing priorities; each strengthens the other.
Language presents another compelling lesson. Sri Lanka’s own history reminds us that language is never simply a means of communication; it can also become a marker of identity, opportunity and exclusion. The language question has occupied a central place in the country’s political history, shaping relationships between communities for decades. Erasmus+, by contrast, treats multilingualism as one of Europe’s greatest strengths. It promotes the idea that linguistic diversity should connect rather than divide societies. Sri Lanka’s continued investment in Sinhala, Tamil and English education should, therefore, be viewed not only as an educational objective but also as a nation-building project. A multilingual citizen is often better equipped to understand perspectives beyond their own community, reducing barriers that have historically fuelled misunderstanding.
Perhaps the most important lesson, however, lies in the values that underpin the programme itself. Erasmus+ is built upon respect for human dignity, equality, inclusion and the rights of minorities. These principles are not peripheral to the programme; they define it. Sri Lanka’s future, likewise, depends upon nurturing a national identity that complements rather than competes with cultural, religious and ethnic identities. Educational exchange can help cultivate that shared civic identity by creating spaces where diversity is encountered as an everyday reality rather than an abstract ideal.
Looking beyond our own borders, such a programme could also redefine Sri Lanka’s place within the region. South Asia continues to grapple with many of the same challenges that Europe once faced, historical grievances, political tensions, social inequalities and limited educational mobility across borders. Sri Lanka is well positioned to lead conversations on regional educational cooperation by establishing an exchange and scholarship model that welcomes students from neighbouring countries, while creating opportunities for Sri Lankan students to study throughout Asia and beyond. In doing so, the country could position itself as a regional hub for higher education, research collaboration and intercultural dialogue.
Such an initiative would strengthen not only universities but also Sri Lanka’s international standing. Educational diplomacy has become an increasingly important component of foreign policy across the world. Countries that attract students, foster academic partnerships and invest in knowledge exchange often build influence that extends well beyond conventional diplomacy. For Sri Lanka, investing in educational mobility would, therefore, represent an investment in both domestic reconciliation and international engagement.
Europe’s experience offers no blueprint that can simply be transplanted to another society. History, politics and culture differ too greatly for simple imitation. But the principles that shaped Erasmus+, mobility, inclusion, cooperation, multilingualism and respect for diversity, are remarkably adaptable. They speak to universal challenges faced by societies seeking to transform historical divisions into shared futures.
Sri Lanka has long recognised education as a pathway to social mobility. The next step is to recognise its potential as a pathway to social cohesion. If Europe could use educational exchange to help overcome the divisions left by war, Sri Lanka can draw inspiration from that experience to imagine its own model, one rooted in our history, responsive to our realities and ambitious enough to invest not only in better graduates, but in a stronger, more united nation.

Soaring Pada Yatra numbers spark alarm over mounting ecological damage in Yala-Kumana parks
By Ifham Nizam ✍️
The rapid expansion of the annual Kataragama Pada Yatra is placing unprecedented pressure on Sri Lanka’s most sensitive protected ecosystems, with conservationists warning that the centuries-old spiritual pilgrimage is increasingly being transformed into a large-scale public event at the expense of wildlife and biodiversity.
Conservationist and researcher Supun Lahiru Prakash has urged the Government and the Department of Wildlife Conservation (DWC) to introduce urgent reforms to protect the Yala-Kumana protected area complex, warning that the country’s natural heritage is “paying the price” for the uncontrolled growth of the pilgrimage.
The 2026 Pada Yatra officially concluded on July 24 after entry to the Kumana National Park was closed at 3.00 p.m.
According to figures cited by Supun, a record 41,077 pilgrims entered through the Kumana National Park, between July 10 and July 24, before proceeding through the Kumana-Yala protected area, to Kataragama.
The figures reveal a steep upward trend. Pilgrim numbers rose from 28,838 in 2022 to 34,604 in 2025 before climbing to 41,077 this year—an increase of more than 42 percent, over four years, and nearly 19 percent, compared with last year alone.
“The Pada Yatra is one of Sri Lanka’s oldest religious traditions, symbolising sacrifice, devotion and endurance,” Prakash said. “However, its spiritual character is steadily being overshadowed by a carnival-like atmosphere that is inflicting increasing damage on two of the country’s most important wildlife reserves.”
He warned that the annual movement of tens of thousands of people through Yala and Kumana National Parks causes severe disturbance to wildlife, while placing enormous strain on fragile ecosystems.
One of the most pressing concerns is waste management.
Despite efforts by Wildlife officials, Supun alleged that authorities this year resorted to burying non-biodegradable waste in pits at locations, including Madametota and Kumana Villuwa, raising fears of long-term soil and groundwater contamination.
“As participant numbers continue to rise, the volume of waste, demand for water, and overall ecological disturbance inevitably increase,” he said.
He also claimed that several unauthorised activities continued inside the protected areas, with little effective control.
These included alleged night-time vehicle movements by security personnel, medical teams and alms-giving groups, the use of powerful lighting that disrupts nocturnal wildlife, operation of generators and loudspeakers, large-scale collection of firewood using tractors, and the disposal of waste from gully bowsers within park boundaries.
He said many of these activities occur beyond the effective control of the Department of Wildlife Conservation, further weakening conservation efforts.
Supun also expressed concern that the pilgrimage has become an attraction for groups whose interests extend beyond religious devotion.
“Alongside genuine pilgrims, the event increasingly attracts adventure tourists, commercial operators, self-proclaimed environmentalists and wildlife photographers, seeking free access to the national parks,” he said.
He further alleged that some senior district administrators have prioritised making the pilgrimage more convenient and sophisticated rather than safeguarding the ecological integrity of the protected areas.
According to Supun, this approach has contributed to regulatory neglect and undermined conservation objectives.
He called on the Government to introduce a comprehensive management framework that would limit participant numbers, strictly enforce laws against unauthorised commercial activities and environmental offences, establish effective solid waste management systems, strengthen the authority and operational capacity of Wildlife officers, and restore the Pada Yatra to its original spiritual and ascetic character.
“The future of both this sacred religious tradition and one of Sri Lanka’s most valuable wildlife landscapes depends on immediate, accountable and conservation-focused intervention,” Supun stressed.
Environmentalists have long cautioned that Yala and Kumana National Parks represent internationally significant biodiversity hotspots supporting elephants, leopards, sloth bears, crocodiles, migratory birds and numerous endemic species, making careful management of human activities within these protected areas essential for their long-term survival.

Dengue epidemic 2026: lessons unlearnt
by Dr Pradeep Kariyawasam ✍️
Former Chief Medical Officer of Health,
Colombo.
Dengue outbreaks have been taking place in the country for 60 or more years, but the large-scale epidemics began only in the 21st century. There are basic understandings and actions that health officials must take if we wish not to see them taking place every year.
First, not all patients who get dengue fever are reported to the Health Authorities as some may get only a mild fever and, after a few days, the fever will go away. Secondly, the vast majority will get treatment from their General Practitioners, and they may not be reported to the area Medical Officer of Health. Thirdly, there is a structural failure in dengue control in this country. Sri Lanka has fought dengue with “ad hoc measures” for over 50 years, relying on periodic “Mosquito Weeks” instead of sustained, year-round surveillance, preventive and control action.
The success of Sri Lanka’s Malaria Control Programme was mainly due to the fact that it had dedicated staff throughout the country to eradicate the disease. Take for example the Epidemiology of Dengue Control Units of the Ministry of Health. They have no dedicated staff in the field to take measures needed to prevent the diseases spreading, especially in major urban centres run by Local Authorities. The issue of understaffing at the Local Authorities is an impediment that has not been addressed by the Ministry.
Dengue spreads to other parts of the country from Colombo through the transport system. Trains and buses operating from the bus stands in Fort and railway yards in Maradana and Fort areas took, not only the persons who contracted the disease, but also infected Aedes mosquitoes. Those state employees, or students from outstations, who get ill in urban areas, go home to rest, in the majority of cases. That is why Matara, Puttalam, Kurunegala, Anuradhapura, and Kandy became dengue hotspots years ago.
As the Chief Medical Officer of Health, I campaigned hard to have all field officer vacancies filled to carry out preventive measures, but the appeals fell on the deaf ears of the provincial and government officials. Colombo’s Public Health Department needed around 450 field officers (Public Health Inspectors, midwives, health instructors, mosquito control assistants) to inspect the city’s 80,000 premises but only had about 180 — leaving inspections badly under-resourced. There were budget constraints that prevented public education campaigns through television and newspaper advertisements. However, I must note that major NGOs and private firms helped me immensely and carried out educational programmes. The International award-winning Green Star programme was launched with their help. It was launched 25 years ago.
The first lesson we have forgotten is that social mobilisation is a must for dengue prevention and control. Unfortunately, hardly any residents have realised the need to keep their premises clean. We cannot expect that from them when garbage mounds are visible everywhere and roadsides are not kept clear of rank vegetation. The Green Star programme was created to motivate the residents to keep their premises mosquito free while the Council took measures to clear the areas of garbage and vegetation. To recognise the efforts of the residents we pasted a ‘Green Star’ sticker on their walls, and they were proud to have one. This programme replicated in areas outside Colombo, too.
The second lesson we have forgotten is that timing of starting dengue prevention work is a key aspect of a successful programme. We have two rainy seasons, although the weather pattern has changed, and we find that sometimes it rains much harder at other times. But it is important to start dengue prevention programmes much before the beginning of the rainy seasons. We used to get information on rainfall from the Department of Meteorology. So, the authorities, local or central, must start programmes in the latter part of April and September and see that all possible rainwater collection sites, utensils, etc., are removed. Canals and drains should be cleaned, biochemicals should be sprayed into gabion walls. More than 10 years ago when the government took action to clear the canal system, and with this kind of spraying, we found that hardly anyone had dengue fever in those areas. Shramadana campaigns are unheard of today, but these must be restarted as the government, or the Municipal or Urban Councils, cannot do everything alone. Social mobilisation is again the key to all this.
It is said that the dengue virus has changed and the herd immunity cannot cope with the new type of virus. Years ago, a study was done in the eastern part of the city in the Wanathamulla area, where it was found that nearly 95% of the children in that area had dengue antibodies in their blood. Although that area was notorious for dengue, later only a few dengue patients were found there although I don’t believe that the mosquito density decreased. For dengue to spread, herd immunity should be low and mosquitoes should be abundant. But reducing mosquito numbers too effectively can lower community herd immunity, creating conditions for sudden major outbreaks as had been found in Singapore’s experience where reduced Aedes populations combined with imported dengue viruses which caused increased transmission. What should be remembered is that the number of Aedes mosquitoes that bite, the number of times they bite, and within which a particular period, determine how a person is infected.
A lot of people wait for a vaccine to be given to them rather than spending time outside their garden destroying mosquito breeding places to prevent them getting the disease. There is a single dose vaccine, named Butantan, which covers all four virus types and could be given in one dose. But it is a long way off from reaching this country so, therefore, every effort should be made to reduce the mosquito population first.
Fourth Lesson we have forgotten is that prevention is the best way to keep away hundreds entering hospitals with dengue fever. Source reduction, larvicide, repellents (DEET), insecticide-treated nets/strips, and remember that Aedes mosquitoes also transmit Chikungunya, Zika, and Yellow Fever — making vector control non-negotiable. What is needed is a formal partnership between public health officials and communities, as in the past. In Colombo, there were 300 Community Development Councils at the time of my retirement. Today only a handful are there. They provided hundreds of volunteers for our educational and preventive and control programmes. There was no cost to the Council as everything was looked after by the NGOs and CSR projects of the private sector firms. Schools willingly participated in most of our programmes and in return we taught them recycling and gave them bins to collect the stuff. All the departments in the Colombo Municipal Council helped even in a small way by sending their staff during a weekend for these programmes. These actions should be restarted. Staff members and volunteers were then appointed into Street Committees, which were given lots of 100 to 200 premises to check for breeding and create awareness. The inspections were carried out once a month. In the same manner they created Dengue Free Zones in housing schemes, settlements, schools and large land parcels in the areas allocated to them using the people living in and around these areas. Unfortunately, there was no continuation of such programmes.
A lot of people request fogging in their areas believing that it could get rid of the epidemic. I see a lot of fogging being done during the present epidemic, too. However, using one machine and carrying out these programmes is dangerous as such action could spread the disease into newer areas. As soon as the mosquitoes get the smell of the smoke they fly into neighbouring regions. I have been advocating that if we fog then use at least 4-5 machines and block out an area and fog from the periphery into the centre, usually into the infected area. That way it is difficult for the mosquitoes to escape.
Mapping is also a key aspect of dengue control. I used GIS mapping for this purpose 20 years ago and that helped us to investigate the reasons for the outbreaks, the direction of the spread and analyse the successes and failures of our programmes. I believe the Colombo Municipal Council is continuing with GIS mapping and we have a proper Epidemiologist now. But it is good if the officers come out and tell the public where the disease is and the direction of the spread as we did 20 years ago. At least then people will take an interest in cleaning up their premises.
The Wolbachia issue: The Wolbachia bacteria were released in 2018 in Colombo and Nugegoda areas and the programme went on for several years. That has been successful in many countries. There is an attempt to restart the programme again, and I believe it should be started in between monsoon periods to mop up the remaining infected mosquitoes. Even for this we need the help of the community to breed and release the Wolbachia infected mosquitoes to the environment.
Every year the epidemic is on the wane towards the end of July and that is a natural phenomenon. In the same manner every year in the May-July and November-January periods we either have smaller outbreaks or epidemics. Therefore, considering the past experience we can see that this epidemic will also go away in a few weeks. But the most important thing is to prepare for the next epidemic as all over the world the number of patients and epidemics is increasing.
