Spread most often by mosquitos in tropical and sub-temperate climates of Asia, Japanese Encephalitis Virus typically affects children under age 15, but is the leading cause of viral encephalitis in children and adults in Asia.

Japanese Encephalitis Virus (JEV)

The most widely spread arbovirus in the world, West Nile Virus is primarily spread to humans through mosquitos. West Nile virus infections may produce febrile illness or severe fever; however, most individuals who are infected with the virus are asymptomatic. Outbreaks of West Nile are so dangerous because, currently, there are not any available vaccines or antiviral treatments.

Dengue viruses are vector-borne diseases commonly found in tropical and subtropical climates that cause fever, nausea, rashes and body aches. In high risk areas, Dengue is the leading cause of death therefore it is essential that there is appropriate investment in surveillance methods that can prevent outbreaks of Dengue. 

Dengue

A viral disease most often spread to humans from domesticated animals in sub-Saharan Africa. Rift Valley Fever is more likely to cause severe illness in the animals than in the humans the virus is spread to.

Rift Valley Fever

Discovered in east Africa, Chikungunya virus is spread by mosquitoes across Asia and South America as well, causing a flu like illness.

Chikungunya virus (CHIKV)

Yellow Fever Virus is primarily spread through mosquitoes in densely populated areas of Africa.

Yellow Fever Virus (YFV)

First isolated in the Zika forest in Uganda, this virus is spread primarily by mosquitos in tropical and subtropical climates.

Vector Borne Diseases

Mosquitoes are one of the most important vectors of arboviruses. Common viruses transmitted by mosquitoes: dengue, zika, yellow fever, chikungunya, and many others.
