Climatic factors affecting density of Anopheles vector mosquitoes in Ampara District, Sri Lanka

Abstract

Background: Apart of many vector-borne diseases malaria played a major role during past decades in Sri Lanka. Controlling strategies had effectively addressed this issue so that there were no malaria patients recently. However it has been observed that abundance of vector mosquitoes in districts like Ampara is high, which signifies a potential of spreading of malaria in the area in future. Identification of the relationship between the climatic factors and vector density could be a cost effective way in controlling the mosquito instead of costly strategies currently followed. This study attempts to identify the relationship exists between climatic factors and the vector density in Ampara District.
