Favipiravir Shows Promise Against Chandipura Virus
Recent studies have brought into light the potential of Favipiravir as a treatment for the Chandipura virus (CHPV). Conducted by the National Institute of Virology in Pune, these preclinical trials indicate that Favipiravir can reduce viral load and improve survival rates in infected animals. The Chandipura virus is endemic to central India and primarily affects children, leading to severe symptoms such as high fever and seizures.
About the Chandipura Virus
The Chandipura virus belongs to the Rhabdoviridae family and is transmitted by sandflies. It was first identified in 1965 in Nagpur, Maharashtra. The virus causes encephalitis, leading to inflammation of the brain. Symptoms include fever, vomiting, altered consciousness, and convulsions.
Transmission and Vector
CHPV is primarily transmitted by female Phlebotomine sandflies, which are most active during the early monsoon season. Studies have indicated that certain mosquito species, particularly Aedes aegypti, could also transmit the virus under laboratory conditions. However, no direct isolation from mosquitoes has been confirmed.
Clinical Manifestations
The clinical presentation of CHPV infection typically includes a rapid onset of fever followed by neurological symptoms. Children under 15 years old are particularly vulnerable. The 2003 outbreak in Andhra Pradesh brought into light the virus’s high fatality rate among this demographic, with many deaths occurring within 48 hours of hospital admission.
Treatment Options
Currently, there is no specific antiviral treatment for CHPV. Symptomatic management is the primary approach, focusing on maintaining airway, breathing, and circulation. Fluid balance, temperature control, and seizure management are critical. Favipiravir is being evaluated as a potential therapeutic option, but clinical trials in humans are still pending.
Preventive Measures
Preventing CHPV infection involves vector control strategies. This includes identifying and eliminating sandfly breeding sites, using insecticides, and promoting sanitation. Personal protective measures such as wearing long clothing and using insect repellents are also recommended to reduce the risk of bites.
Future Research Directions
Ongoing research aims to develop a vaccine against CHPV. The National Institute of Virology is working on this, as current measures are insufficient to combat the high fatality rates, especially among children. The efficacy of Favipiravir will be further evaluated in animal studies before human trials commence.
