About PDNN
I am a PhD candidate and completing my doctoral soon. I have been working on different aspects of dengue virus infections in Sri Lanka for the last 3 years. I also serve as a secretary for the Kandy Chapter for the Sri Lankan Society for Microbiology. I like to disseminate knowledge in the scientific and social media. I am a social enterprenuer working on education and research related startup.

About F
I am an academic and a virologist who undertake research in viral infections in children and adults. My research interest are respiratory and dengue virus infections in different geo-climatic zones on Sri Lanka. I also undertake research on HBV infections and immunity following vaccination. I train PG research students MSc, MPhil and PhD projects in Sri Lanka and some of my students have attachments in overseas universities. I publish locally and internationally and my aim is to disseminate knowledge and improve the local scholarship. I have been lagging behind in social media communications and I must move forward in that direction too.

Dengue is an acute viral or viral haemorrhagic fever caused by a flavivirus of four well-known serotypes (DENV-1, DENV-2, DENV-3 and DENV-4). Aedes aegypti and Aedes albopictus mosquitoes transmit DENV, which causes symptomatic dengue in some infected individuals and asymptomatic infection in others. Although Sri Lanka has been experiencing dengue outbreaks since 1960, the disease burden and severity has increased in the last two decades, contributing to significant morbidity and mortality in the island. Innovative strategic methods must be planned and implemented for effective dengue control, targeting dengue vectors via multiple methods. Some recent developments in vector control include the use of insecticide-treated long lasting mosquito nets, lethal ovitraps, spatial repellents, genetically modified mosquitoes and Wolbachia-infected Aedes. Some of these new methods might play an important role in the long-term prevention and control of dengue. The current review highlights the importance of pooling existing knowledge and resources to work on capacity building using all available human and financial resources to optimize the vector control programme. These efforts would facilitate and improve regional cooperation, foster networking and encourage sustainable co-ordination to retain effective control methods. Motivated staff working on vector control, prediction models such as geographic information systems (GIS) to detect future dengue outbreaks and coordination of control methods in risk areas within a country or implementing country-wide specific strategic control measures will be crucial to reduce the existing dengue burden
