Chandipura virus is a rare but potentially life-threatening virus that mainly affects children and can cause sudden fever and acute encephalitis. Recent outbreaks in India have renewed public health concern due to its high fatality rate among severe cases.
Chandipura Virus was first isolated in 1965 during investigations of patients with acute febrile illness in Chandipura village, Maharashtra, India, by scientists from the National Institute of Virology (NIV), Pune. The virus was named after the village where it was first identified.
CHPV belongs to the family Rhabdoviridae and the genus Vesiculovirus. It is an enveloped, bullet-shaped virus with a single-stranded, negative-sense RNA genome and is genetically related to vesiculoviruses, although it is distinct from the rabies virus.
Since its discovery, Chandipura virus has been recognized as an important cause of outbreaks of acute encephalitis syndrome (AES), particularly among children in parts of India. Continued surveillance and research have improved our understanding of its transmission, diagnosis, and public health impact.
