SIXTY YEARS AGO: THE ASSASSINATION OF PRESIDENT KENNEDY
SIX SECONDS IN DALLAS – I
By Jayantha Somasundaram
It was 12:30pm 22nd November 1963 at Dealey Plaza in Dallas Texas. President Kennedy’s Motorcade was on Elm Street, moving at 18 kmph. The Presidential Limousine was number two in the Motorcade, following the lead police car. In the limousine next to the driver sat Roy Kellerman, ranking Secret Service Agent (the presidential protective detail) behind them in the jump seats were Texas Governor John and Nellie Connally, and behind them were President John and Jackie Kennedy. Then came six seconds of gunfire; Kennedy and Connally were hit, the President fatally. Forty five minutes later at Parkland Memorial Hospital President Kennedy was pronounced dead.
A week later Kenndy’s successor President Lyndon Johnson appointed a six-member commission chaired by Chief Justice Earle Warren, and including future President Gerald Ford and former Central Intelligence Agency (CIA) Director Allen Dulles, to investigate the assassination. In September 1964 they presented their findings in what has come to be called the Warren Commission Report.
The Warren Commission concluded that 24-year old Lee Harvey Oswald assassinated Kennedy without the aid or instigation of a third party. That using a Mannlicher-Carcano Carbine he fired from the sixth floor window of the Texas School Book Depository building in Dealey Plaza where he worked. He then took a bus and a taxi, arriving at his home at 1:00pm, leaving shortly thereafter armed with a pistol. When confronted by police officer Tippit at 1:15 Oswald shot and killed him. After he was arrested that afternoon in a cinema he was held in a Dallas jail until the 24th when nightclub owner Jack L. Ruby, also acting alone, shot and killed him.
All the doctors who treated Kennedy at Parkland Memorial were explicit: The cause of death was a massive head injury from a gunshot wound at the left temple. Besides the head injuries there were other wounds, a back wound nearly six inches below the collar alongside Kennedy’s spine and a throat wound in front.
If the wound at his left temple and throat were entry wounds, they could not have originated from the Book Depository because at the time of the shooting that building was positioned almost directly behind the Motorcade. Moreover nearly two-thirds of the witnesses questioned as to the origin of the gun shots, identified a grassy knoll located in front of the Motorcade as their source.
Magic Bullet
The Commission claimed that Oswald’s rifle could fire a bullet every 2.3 seconds. On the basis of cine films taken by spectators in Dealey Plaza it was established that the firing had lasted six seconds. Hence a maximum of three bullets could have been fired by Oswald’s weapon in the given time. One bullet missed the Motorcade and embedded itself in the pavement. If another was responsible for the head wounds then the third bullet had to have inflicted all the other wounds. So it would have had to enter Kennedy’s back torso and in the words of the Warren Report: ‘pierced the President’s throat and also caused Governor Connally’s wounds.’
The Warren Commission therefore created the ‘magic bullet’ which was fired from the Book Depository into Kennedy’s back, then turned through 120º and travelled up the body, turned through another 120º at his neck where it exited and then went on to inflict the wounds in Connally’s back, wrist and leg.
At 12:44 by which time all other police patrol cars were ordered to converge on Dealey Plaza, Police Officer J.D.Tippit was detailed to Central Oak Cliff – the location of his death – ‘so that you will be at large for any emergency that comes in.’ Witnesses said that Tippit’s killer placed his elbows on the car window and appeared to be chatting with the officer. Had Tippit accosted his killer suspicious that he was the President’s assassin, the least he would have done was draw his gun and step out of the Police Car.
The only witness who claims that he saw Oswald fire at the President was Howard Brennan. He provided a description of Oswald to Secret Service Agent Sorrel after one pm. Tippit was shot at 1:15. At 12:45 however the Dallas Police had broadcast a description of Oswald. Moreover when Oswald was arrested that afternoon he was charged with Tippit’s killing; only twenty four hours later would Oswald be told that he would be charged with the assassination of the President. So why was Tippit’s killer wanted by the Dallas Police half an hour before Tippit was shot?
How reliable in any case was Brennan as a witness. Though he provided an accurate description of Oswald minutes after the assassination, just hours later that day he failed to pick Oswald out of a police line up! Brennan also told police that through the sixth floor window of the Book Depository he could see Oswald walking about. But the upper portion of that window was shut. So the Oswald that Brennan saw must have been walking about on his knees!
Jack Ruby
Once Oswald was identified as the President’s assassin it would be assumed that he was securely guarded and protected. Then how did Ruby get close enough to him in the Dallas Police garage to be able to kill him? Ruby who ran a couple of nightclubs in Dallas was said to be on speaking terms with about “700 of the 1,200 men on the police force.” There were standing orders that policemen and their guests be served anything on the house. In addition he also “made women available to officers.”
When Ruby appeared before the Warren Commission he was warned by both the Police and the Secret Service not to disclose certain matters. So he requested a transfer to Washington so that they “might get a fair shake out of him… Gentlemen,” he said “my life is in danger here.” He also said “someone in the Police Department is guilty of giving the information as to when Oswald was coming down (to the garage where he was killed).”
On November 14th a meeting took place in Ruby’s night club. The participants were Ruby, Tippit and Bernard Weisman, one of the leaders of the political right in Dallas. A crude but signed defamatory advertisement attacking the President was taken out by Weisman in the 22nd Dallas Morning News.
Ruby was identified hours before the assassination on the grassy knoll sporting a gun case and he was at Parkland Memorial after the assassination. Ruby was associated with elements of the US Armed Forces who were running guns to anti-Castro forces in Cuba. In a letter to the then Director of the CIA Richard Helms, Warren Commission Lawyers remarked that Ruby “was involved with members of the underworld…A Government informant in Chicago has reported that such Cubans (involved in gun-running to Cuba) were behind the Kennedy assassin.”
Fate of Witnesses
Interestingly witnesses like Mrs Tice who had identified Ruby at Parkland were harassed and threatened. Other witnesses suffered worse. One witness was shot through the head. Another hanged herself to death in the Dallas jail. After another witness was interviewed by independent investigators her son was arrested and injured when he fell out of a window in an alleged attempt to escape from the Dallas Police.
Two reporters visited Ruby’s apartment just after he had killed Oswald. One, a writer for the Dallas Times Herald was found dead in his Dallas apartment, the victim of a karate attack; the Dallas Police were unable to find his killer. The other a former Dallas resident and a prize-winning reporter for a California newspaper was shot to death in a California police station; the police were able to locate his killer – he was a local police officer. An eyewitness to the Tippit murder Mrs Acquilla Clemons stated that she was implicitly threatened with harm by a Dallas police officer if she disclosed what she had seen.
Abraham Bolden the first Black to serve on the White House Secret Service detail announced that he wanted to testify before the Warren Commission, because he was aware of the failure of the Service to take adequate precautions. Bolden was indicted by the Federal Government and charged with trying to sell government files.
Marina Oswald, Lee’s Russian widow had from the outset insisted on her husband’s innocence. But after she was threatened with deportation by Agents of the FBI her testimony changed. Jean Hill who had seen Ruby in Dealey Plaza soon after the assassination said that “the FBI was here for days. They practically lived here. They just didn’t like what I told them I had seen and heard when the President was assassinated. For years I have told the truth, but I have two children to support. I am a public school teacher. My Principal said that it would be best not to talk about the assassination, and I just can’t go through it all again. I can’t believe the Warren Report. I know it’s all a lie, because I was there when it happened!”
“To believe the Warren Commission” writes Robert Anson in They’ve Killed the President, “you have to believe that bullets pause in midair and make ninety degree right hand turns; that a poor marksman can do what experts cannot; that Newtonian laws of motion were not operating on November 22, that a man can be in two places at once; that atoms are able to change their structure; that everything in life is mere chance.”
The Hell Hole
What was the political climate in Dallas that November day in 1963? “God made big people like Kennedy. And God made little people like me, “drawled one Dallas resident. “But Colt made the .45 to even things out. “
Dallas residents sported ‘KO the Kennedys’ car stickers. There were lewd jokes about the hotline to the Vatican that ended in a Rome Sewer. On the eve of the assassination Protestant intolerance reached its zenith. A Baptist Convention was told “one of the greatest blunders in history was the election of a Roman Catholic President.” And that in future one should not vote Democrat or Republican but Protestant.
A Dallas newspaper accused Kennedy of being a follower of ‘the communist line, which is atheistic and godless.’ That Kennedy would ‘take a man’s income tax and without his permission spend it abroad as foreign aid in countries that deny a supreme creator!’
When the President landed in Dallas he faced placards which read ‘Kennedy Khrushchev and (Martin Luther) King’ and ‘Kennedy the Communist Party wants you re-elected.’
As the Presidential party embarked at Forth Worth Airport one of the local drivers asked Kennedy’s Special Assistant Larry O’Brian: Flying to Dallas? And when the latter nodded the man said “That’s the hell hole of the world!”

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.
