Abstract
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.
Highlights
Though DF and DHF have been around for at least the last thirty years in Sri Lanka, it was not until 2000 that dengue was identified as a major public health problem in the island

Summary
Though DF and DHF have been around for at least the last thirty years in Sri Lanka, it was not until 2000 that dengue was identified as a major public health problem in the island. A number of studies have been carried out worldwide to identify the dynamics of DENV within the vector to determine how they contribute to the changes in the dynamics of DF/DHF in the relevant region. Such studies have been lacking in Sri Lanka.
