Gujarat is currently facing a resurgence of the Chandipura virus, following the previous outbreak which was the worst in the country for over two decades. This renewed prevalence has become alarming, especially as it has resulted in the deaths of three children within a matter of days. The most recent victim was a six-year-old from Rajasthan, who passed away at Himmatnagar Civil Hospital in Sabarkantha after being diagnosed with the virus.

Earlier this week, two toddlers aged three and four died in Panchmahal district, indicating that the virus is spreading geographically beyond its initial hotspot. These events have prompted health authorities to initiate a comprehensive containment strategy in the affected regions.

Medical teams have been deployed to conduct door-to-door surveillance, insecticide spraying, and health screenings. Officials are urging parents to seek immediate medical attention if children show symptoms such as sudden high fever, vomiting, or convulsions, as the condition can deteriorate rapidly.

Characteristics of the Virus

The Chandipura virus, although less commonly discussed than dengue or chikungunya, is regarded by public health experts as one of the more perilous vector-borne viral infections in India due to its high fatality rate and swift onset. Identified in 1965 in Maharashtra, the virus belongs to the Rhabdoviridae family, which also includes the rabies virus.

Traditionally, outbreaks have been localized to western, central, and southern India, particularly affecting states such as Gujarat, Maharashtra, Rajasthan, Madhya Pradesh, and Andhra Pradesh. Transmission primarily occurs through bites from infected sandflies, although evidence suggests that ticks and mosquitoes may also contribute.

Unlike respiratory viruses, the Chandipura virus does not transmit person-to-person through casual contact. The largest outbreak in recent history occurred in 2024, with widespread cases of Acute Encephalitis Syndrome (AES), leading to a significant number of confirmed Chandipura cases, making it the most extensive outbreak in over 20 years.

Absence of Effective Treatments

A major hurdle in addressing the Chandipura virus is the lack of a specific antiviral treatment or vaccine. Patients primarily receive supportive care aimed at managing symptoms like fever and seizures while sustaining vital functions. Early hospitalisation can markedly enhance survival outcomes, although the virus typically progresses quickly.

Experts affirm that while the disease remains aggressive, children who recover usually do so without enduring long-term neurological impairments. The absence of a vaccine underscores the importance of preventive measures.

Dr. Sumit Jain, an internal medicine specialist, recommends community efforts to minimise exposure to vector insects. This includes maintaining cleanliness, preventing stagnant water accumulation, and using protective clothing for children. Public awareness and prompt reporting of suspected cases are deemed crucial in mitigating outbreaks.

As conditions in monsoon seasons facilitate the breeding of sandflies, public health experts stress the necessity for vigilance. Any child exhibiting sudden fever coupled with neurological symptoms requires immediate medical attention to improve recovery chances.
