The Government of Sri Lanka announced plans for a pilot program to combat the dengue outbreak. A bacteria, Wolbachia, is to be injected into the bodies of the Aedes aegypti mosquitoes, the main carriers of the dengue virus, on 17 February in the Dematagoda and Nugegoda areas. While the bacteria is inside the body of a vector, it competes with the dengue virus for food and energy. This makes it hard for the virus to reproduce inside the mosquito and subsequently the transmission of the virus is inhibited by the bacteria. (Govt. of Sri Lanka, 23 Jan 2020)
