Health Experts Review Surge in Chandipura Virus and AES Cases in Central India

Prof. Atul Goel and health experts reviewed Chandipura virus and Acute Encephalitis Syndrome (AES) cases in Gujarat, Rajasthan, and Madhya Pradesh. Findings indicate infectious agents contribute to a minor part of AES cases. The team stresses the need for comprehensive studies and vector control measures.

Prof. Atul Goel, Directorate General of Health Services (DGHS), Union Health Ministry, along with experts from AIIMS, Kalawati Saran Children's Hospital, and the National Institute of Mental Health & Neurosciences (NIMHANS), reviewed the Chandipura virus and Acute Encephalitis Syndrome (AES) cases in Gujarat, Rajasthan, and Madhya Pradesh.

Following a detailed discussion and review, the experts concluded that infectious agents contribute to only a small proportion of AES cases nationwide. They emphasized the need for comprehensive epidemiological, environmental, and entomological studies of AES cases reported in Gujarat.

A multidisciplinary central team from NCDC, ICMR, and DAHD is being deployed to assist the State of Gujarat with these investigations. AES is a group of clinically similar neurologic conditions caused by various pathogens, including viruses like JE, Dengue, HSV, CHPV, and West Nile.

Chandipura Virus (CHPV), a member of the Rhabdoviridae family, causes sporadic cases and outbreaks, primarily during the monsoon season. Transmitted by vectors like sand flies and ticks, CHPV primarily affects children under 15 years. While no specific treatment exists, symptomatic management and timely referrals can improve outcomes.

Since early June 2024, Gujarat reported 78 AES cases, with 75 cases from 21 districts/corporations, 2 from Rajasthan, and 1 from Madhya Pradesh. Of these, 28 have been fatal. Among the 76 samples tested at NIV Pune, 9 were confirmed positive for CHPV, all from Gujarat.
