Dengue, caused by the dengue virus (DENV) is the most important vector borne infection in the tropics and can present as dengue fever (DF) or dengue haemorrhagic fever (DHF).1 DENV exists as four different serotypes, all of which have been circulating in Sri Lanka for the past 30 years. 2 DENVs are transmitted by the mosquito species Aedes aegyptii and Aedes albopictus, both of which are endemic to the South Asian region of the world. In Sri Lanka, the primary vector in transmitting DENV is A. aegyptii while A. albopictus serves as the secondary vector.
