A recent rise in suspected Chandipura virus (CHPV) cases in Gujarat, particularly among children, has caused public health concern. This article provides a clinical overview of CHPV, outlining its causes, symptoms, and preventive measures.

Etiology and Pathogenesis

CHPV is a mosquito-borne, single-stranded RNA virus belonging to the Rhabdoviridae family. First identified in an outbreak of acute encephalitis in Maharashtra, India, in 1965, it causes inflammation of the brain (encephalitis). The primary mode of transmission is suspected to be through the bite of infected sandflies, with potential roles for mosquitoes and ticks under investigation.

Clinical Presentation

Chandipura virus (CHPV) infection can present with a range of symptoms, including:

• Fever
• Flu-like symptoms (malaise, myalgia)
• Gastrointestinal complaints (vomiting, diarrhea)
• Headache

These symptoms may progress rapidly, potentially leading to severe neurological complications. Early diagnosis and prompt medical intervention are crucial for optimal patient outcomes.

Epidemiology and Risk Factors

CHPV outbreaks exhibit a seasonal pattern, with a higher incidence during the monsoon season in rural areas. Children aged 9 months to 14 years appear to be most susceptible.

Public Health Measures

Currently, there is no specific treatment for CHPV. Management focuses on supportive care and controlling symptoms. Public health measures play a vital role in preventing outbreaks. These include:

• Vector control programs targeting sandflies, including spraying insecticides and using bed nets.
• Raising public awareness about the importance of personal protective measures, such as wearing long-sleeved clothing and using insect repellents during peak sandfly activity periods (dusk and dawn).

Conclusion

The ongoing situation in Gujarat necessitates close monitoring by public health authorities. While the confirmed cause of the recent fatalities awaits further investigation, healthcare professionals should maintain a high index of suspicion for CHPV in patients presenting with compatible symptoms. Implementing preventive measures and promoting public education are crucial steps in mitigating the impact of this potentially serious viral illness.
