This preprint review examines Chandipura virus (CHPV), a sandfly-transmitted arbovirus in India, focusing on its origin, evolution, transmission dynamics, epidemiology, and current understanding of pathology and clinical manifestations. It describes CHPV as closely related to vesicular stomatitis virus but notable for human infection, with severe rapid-onset disease including high fever, abnormal sensory perception, and seizures, and it highlights the 2003–2004 central India encephalitis outbreak with high case fatality among children. A stated limitation is that the work is a preprint and not peer reviewed, with potentially preliminary data, and it provides a broad synthesis rather than original experiments. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Chandipura virus (CHPV), an arbovirus belonging to genus Vesiculovirus in the family Rhabdoviridae has gained global attention as an encephalitis causing virus after the 2003-2004 outbreaks in central India. Transmitted by sandflies, particularly the female phlebotomine sandfly, CHPV is closely related to the Vesicular Stomatitis Virus but is distinguished by its ability to infect humans. The virus was first discovered in 1966 by researchers at the Virus Research Centre in Pune, India, during an investigation of febrile illnesses suspected to be caused by dengue or chikungunya viruses. However, CHPV’s public health importance was underscored only after a major outbreak of encephalitis with high case fatality rates among children in 2003. Clinically, CHPV infection manifests as a rapid-onset, severe illness characterized by high fever, abnormal sensory perception, and seizures, with an incubation period of just 24 to 48 hours. The virus’s ability to cause such severe symptoms and the speed of disease progression pose significant challenges for diagnosis and treatment. This review explores the origin, evolution, and transmission dynamics of CHPV, highlighting the role of sandflies as vectors and the impact of the virus on public health. The review also discusses the epidemiology of CHPV, including notable outbreaks, and the current understanding of its pathology and clinical manifestations. Given the ongoing threat posed by CHPV, there is a pressing need for enhanced surveillance, improved diagnostic methods, and the development of effective vaccines and treatment strategies to mitigate the impact of this emerging viral threat.
