Risk assessment was carried out for vector borne diseases (VBDs) in displaced persons of Rohingya refugees camps, Bangladesh to control the danger posed by these diseases . This paper brings together the latest malaria surveillance data of the affected Cox Bazar district where one million refugees settled from Mynamar. Risk assessment for Rhingya refugee camps on the basis of abiotic and biotic factors revealed that Low risk for dengue due to no storage practice in Refugees camp and Population largely immune . There was moderate risk for malaria in refugee’s camps with potential for epidemic transmission in absence of interventions and active surveillance in the coming transmission. Rice field with water nearby camps is one of risk factor for transmission of Japanese Encephalitis. But pigs and birds population are not available in refugees camps and catchment area. Thus there was pig cycle or Bird cycle not possible for Japanese Encephalitis. The risk of transmission of malaria is a function of crowding in the refugees camps and might be more in post moon season. At present breeding places are few in these camps so Anti larval measures should carried out by Temphos application which will look after mother foci of primary vectors of malaria and dengue and no more proliferation possible during raining season to mitigate the risk. Entomological surveillance revealed that competent vectors for malaria and dengue are not present now, but vector activity will high during coming transmission months when environmental conditions may become permissive.
