Aedes albopictus
Chikungunya is one of the neglected tropical diseases of Bangladesh. It is a viral disease which is transmitted to humans by infected mosquitoes – including "Aedes aegypti" and "Aedes albopictus", which is present in Bangladesh. It is an RNA virus that belongs to the alphavirus genus of the family Togaviridae. It was first described during an outbreak in southern Tanzania in 1952. Since then, CHIKV has been reported to cause several large-scale outbreaks in Africa, India, Southeast Asia, Western Pacific and Americas. In the South-East Asia region, Chikungunya virus is maintained in the human population by a human-mosquito-human transmission cycle that differs from the sylvatic transmission cycle on the African continent.
