A National Joint Outbreak Response Team (NJORT) has been deployed to assist the Gujarat State Government in undertaking public health measures and for conducting a detailed epidemiological investigation into the outbreak. A joint advisory from NCDC and NCVBDC is being issued to guide the neighboring States reporting AES cases.
CHPV is a member of Rhabdoviridae family and known to cause sporadic cases and outbreaks in western, central and southern parts of the country especially during the monsoon season. It is transmitted by vectors such as mosquitoes, sand flies and ticks. Vector control, hygiene and awareness are the only measures available against the disease. The disease affects mostly children under 15 years of age and can present with a febrile illness that may progress to convulsions, coma and in some cases, may result in death. Although there is no specific treatment available for CHPV and management is symptomatic, timely referral of suspected AES cases to designated facilities can improve outcomes.
