Prof Malavige predicts dengue will get worse with climate change unless…

The impact of dengue will probably get worse due to climate change, Professor Neelika Malavige of the Department of Immunology and Molecular Medicine, University of Sri Jayewardenepura and Head of Dengue Global Programme and Scientific Affairs, Drugs for Neglected Diseases Initiative (DNDi) has said recently at a conference organized by DNDi in Thailand.

The conference was held in parallel to the 20th International Congress for Tropical Medicine and Malaria (ICTMM). DNDi is a non-profit drug research and development (R&D) organization that is developing new treatments for neglected diseases like dengue.

Professor Malavige said that as the world got warmer, dengue would spread to Europe and North America. She added that dengue fever had become increasingly common in recent decades worldwide with around 390 million infections occurring each year. Climate change had been identified by WHO and other national, and international health authorities as one of the primary causes of the global spread of dengue fever and other Aedes aegypti-transmitted viral infections, she said.

“The weather has an impact on vector-borne illnesses. Rainfall and ambient temperature are referred to as macro factors that influence dengue since they directly impact Aedes aegypti population density,” Prof. Malavige said.

The population density of Aedes aegypti declines when the average temperature is lower.

“The larval development time, larval and adult survival, and duration of the gonotrophic cycle of the dengue vector are directly affected by climatic factors such as ambient temperatures, rainfall, and relative humidity. Vectors are increasing due to increasing temperature. As temperature increases the mosquitoes mature faster, giving them more time to spread the disease,” she said.

On the other hand, increasing population, lifestyle changes and uncontrolled urbanization are also reasons for the rapid global spatial spread of dengue, she said.

“Risk factors like obesity, and diabetes are also increasing among the people. Those with these diseases are more likely to suffer from more serious forms of dengue.”

Doctors and medical administrators in countries with dengue were efficient in managing the disease and this explains why the mortality is lower. However, when there was an overload of cases, the system monitoring and evaluating dengue patients for severity suffers because keeping an eye on each patients becomes an impossibility, Professor Malavige said. “There is a shift in the age of those who get infected. Earlier it was a disease that children got. Now you can find patients from all age groups,” she said.

Commenting on attempts to develop a vaccine for dengue, most recently by Takeda Pharmaceutical Company, Professor Malavige said that the data available looked promising. The vaccine could be soon registered in Latin America and Asia. The current data shows that it reduces hospitalization by about 80%. This is similar to the effectiveness of COVID vaccine, although long term safety data for a dengue vaccine is needed for all serotypes. However, it is unfortunate that there is not yet a designated treatment for dengue.

“Dengue is a disease of the low income countries. Infection of the developing world. Each year hundreds of millions of people are affected by dengue but there is still no treatment for it. Would we have a vaccine so fast if COVID too was a disease of the low income countries? The amount of research done on COVID for the last two years is immense. Not even 10% of the research volume has been directed for dengue. There are not enough funds for dengue research. Global North has done some research but the researchers are far away from the disease. The perspective will be different if they too had to live with dengue,” she said.

Dr. Isabela Ribeiro, Viral Diseases Cluster Director, DNDi said that countries of the Global South must cooperate with each other to find a cure for dengue. There are a number of pharmaceutical powerhouses in the Global South and they can work together to find a cure, she said.

“The World Health Organization’s (WHO) report on neglected tropical diseases, ‘A road map for neglected tropical diseases 2021–2030’ does not mention a treatment for dengue. Their focus is on vaccines and vector control,” she said.

Meanwhile, Jean-Michel Piedagnel, South-East Asia Director, DNDi said that while taking steps to prevent dengue, from vector control to using mosquito repellant was important, it should not be allowed to mask the fact that there was no treatment.

“There is no treatment because there is not enough funding. We must not forget that. Each year hundreds of millions are affected by dengue. They deserve treatment,” he said.

Easter Sunday carnage: WR asks AG to question Dappula on ‘grand conspiracy’ claim

Published

on

Former Justice Minister Dr. Wijeyadasa Rajapakshe, PC, yesterday urged the Department (CID) to question former Attorney General Dappula de Livera, PC, regarding his claim that the 2019 Easter Sunday carnage was a grand conspiracy.

Dr. Rajapakshe, a former President of the Bar Association of Sri Lanka, pointed out that the former Director of the Directorate of Military Intelligence (DMI) and the ex-head of State Intelligence Service (SIS) had been arrested under the Prevention of Terrorism Act (PTA) on the basis of unsubstantiated allegations levelled by a fugitive from the Sri Lankan law that Gen. Sallay masterminded the Easter Sunday carnage.

The CID arrested Sallay on February 25, 2026, at Peliyagoda.

Attorney General Parinda Ranasinghe, (Jnr), PC, could not under any circumstances further delay seeking an opportunity for the CID to question de Livera. The ex-Minister said so yesterday (15) when The Island sought his explanation regarding the claim he made in Kandy on Sunday that de Livera alleged a grand conspiracy after the then President Gotabaya Rajapaksa declined to grant him a one-year extension.

Ex-parliamentarian Rajapakshe quoted President Rajapaksa as having told him that de Livera was told of his inability to grant the outgoing AG’s request. However, the then government offered him the opportunity to serve as Sri Lanka’s High Commissioner in Canada. He declined that offer.

Responding to The Island queries, Rajapakshe said that though de Livera succeeded in thwarting the Terrorist Investigation Department (TID) from questioning him over his claim made on the eve of his retirement, in May, 2021. According to him, when a major controversy erupted over De Livera’s claim, the TID had been sent to record his statement.

Having evaded the police and successfully moved the Court of Appeal against the TID, the former AG sent a lawyer to the TID on his behalf. That lawyer declared that a seven-paged legal objection to the matter in question has been submitted to the TID.

“Archbishop of Colombo Malcolm Cardinal Ranjith and all those who had been demanding justice for Easter Sunday victims should urge AG Parinda Ranasinghe (Junior), PC to record de Livera’s statement. The ex-Minister said that the Leader of the House, Minister Bimal Ratnayake, disclosed that SSP Shanie Abeysekera and Senior DIG Ravi Seneviratne had been appointed Director, CID and Secretary to the Public Security Ministry, respectively, on the Cardinal’s advice. Therefore, the Cardinal should stress the urgent need to record the former AG’s statement.

Dappula de Livera received his appointment on 10 May, 2019, just weeks after the Easter Sunday carnage, and retired on 25 May, 2025.

On the eve of his retirement, alleging that there had been a grand conspiracy, de Livera said that the information by the SIS with times, targets, places, method of attacks and other information proved the conspiracy. He said that the identities of those involved in the grand conspiracy must come by the way of evidence.

Wijeyadasa Rajapakshe said that investigations into the Easter Sunday carnage couldn’t be brought to a successful conclusion until de Livera revealed what he knew about the grand conspiracy, mastermind or whatever various interested parties chose to call the attacks.

The government sent a CID team to Paris to record a statement of Azad Moulana, a fugitive seeking asylum in Switzerland and who implicated Sallay in the Easter Sunday attacks. “This matter is so serious de Livera must consider volunteering to assist the investigation,” ex-lawmaker Rajapakshe said, challenging all those genuinely concerned about the inordinate delay in bringing the high profile investigation into a conclusion to push for immediate questioning of de Livera.

Having spearheaded the Easter Sunday investigation at the onset of the probe, de Livera could shed light on the alleged conspiracy if he really meant his declaration on the eve of his retirement, Dr. Rajapakshe said.

Beijing Capital Airlines to resume direct flights between Beijing and Colombo in September this year, restoring an important air link and strengthening tourism, business, and people-to-people connectivity. This service will complement the existing 23 weekly flights between Mainland China and Colombo.

This was announced at Sri Lanka tourism briefing and networking reception held recently in Beijing. Sri Lanka embassy in Beijing with the support of the Sri Lanka Tourism Promotion Bureau (SLTPB) held the event that brought together over 120 representatives from China’s travel trade, media organizations, tourism-related investment sector, airlines, content creation industry, and Meetings, Incentives, Conferences and Exhibitions (MICE) sector.

Among the participants were representatives of leading Chinese travel companies and media organisations, including China Tourism Group Travel Services Corporation Limited, China International Travel Service (CITS), China Youth Travel Service (CYTS), Spring Tour, Mafengwo, Xinhua News Agency, People’s Daily, Global Times, Guangming Online, and China Times, together with representatives of SriLankan Airlines and Beijing Capital Airlines.

The event, led by Deputy Chief of Mission (DCM), Poornima Gunasekera marked the resumption of the Embassy’s direct engagement with China’s travel trade and media community after a considerable period and provided a platform to outline new initiatives aimed at strengthening tourism cooperation between Sri Lanka and China ahead of the 70th Anniversary of the establishment of diplomatic relations between the two countries in 2027.

In her keynote address, the DCM highlighted the longstanding historical ties between Sri Lanka and China, dating back more than 2,000 years through the ancient Maritime Silk Route, and stressed tourism as a key channel for deepening people-to-people exchanges. She noted Sri Lanka’s strong tourism recovery, with over two million international arrivals in 2025, and reaffirmed the country’s image as a safe, peaceful, and welcoming destination. She also highlighted the Government’s expanded visa-free entry programme covering 40 countries, including China, designed to make travel easier and more convenient.

She emphasised Sri Lanka’s unique tourism offering, which combines exceptional diversity within a compact geographical area. Within just 65,610 square kilometres—about four times the size of Beijing—visitors can experience beaches, UNESCO World Heritage Sites, wildlife safaris, tea country, wellness tourism, adventure activities, cultural heritage, gemstones, and authentic Sri Lankan hospitality. She also underlined improved connectivity, noting that a direct flight from Beijing to Colombo takes around seven hours, making Sri Lanka a convenient option for Chinese travellers within broader Asian travel itineraries.

A delegation of the United Nations Subcommittee on Prevention of Torture (SPT) is in Colombo. The SPT’s second visit, from 15 to 24 June 2026, takes place amidst the ongoing debate over the NPP government’s decision to bring in a new anti-terrorism law in place of the Prevention of Terrorism Act (PTA) enacted in 1979.

Some political parties, and civil society groups, have criticised the NPP move as the ruling party, during the presidential and parliamentary polls campaigns, promised to abolish the PTA.

The SPT conducted its first visit to Sri Lanka in April 2019, following Sri Lanka’s accession to the Optional Protocol to the Convention against Torture (OPCAT) in December 2017. Upon accession, the Human Rights Commission of Sri Lanka (HRCSL) was designated as the National Preventive Mechanism (NPM), under OPCAT, by the Government of Sri Lanka.

The Foreign Ministry said that the four-member SPT delegation was scheduled to hold meetings at ministerial level, and engage with senior officials of relevant ministries, departments and institutions. The delegation would also meet representatives of the Human Rights Commission of Sri Lanka and members of civil society, the ministry said.

“The Government of Sri Lanka will engage with the Subcommittee in an open, constructive, and transparent manner, consistent with its policy of continued engagement with the United Nations, and in fulfilment of its Treaty Body obligations undertaken voluntarily and enshrined in relevant international instruments, in accordance with the Constitution.

The delegation will comprise Ms. Aisha Shujune Muhammad (Maldives) (Head of delegation); Jakub Julian Czepek (Poland); Ms. Anica Tomsic (Croatia); and Nika Kvaratskhelia (Georgia). They will be accompanied by officials of the SPT Secretariat in Geneva, Switzerland.”
