Other vector borne arbo-viral diseases
Yellow fever is an acute viral haemorrhagic disease endemic in tropical and subtropical areas in South America and Africa, but not in Asia. The yellow fever vaccine offers full protection against infection. Among other mosquito vectors, Aedes aegypti is one the primary urban transmission vector.
There are around 600 million people at risk living in endemic areas and estimated 200 000 cases (causing 30 000 deaths) per year.
Japanese encephalitis (JE) is a viral disease in Asia which causes inflammation of the membranes around the brain. It is transmitted by mosquitoes and infects humans, domestic pigs, and wild birds. Most JE cases experience a mild fever or headaches. However, severe cases can be dangerous and lethal.
