Vector competence of certain Culex and Aedes mosquitoes for the Chittoor virus, the Indian variant of the Batai virus.

Chittoor virus (CHITV), a mosquito-borne bunyavirus (Orthobunyavirus: Bunyaviridae) isolated in India, has been found to be antigenically close to the Batai virus (BATV), which has a wide distribution across Asia, Europe, and Africa. The latter virus causes influenza-like illness in humans and mild illness in sheep and goats. BATV has been involved in genetic reassortment with other bunyaviruses, generating novel genome combinations and causing severe clinical manifestations including hemorrhagic fever.
