Two instances of Nipah virus, a rare disease transmitted by bats, have been identified at a medical facility in India, putting one patient in critical condition. This deadly virus, which can lead to brain swelling and death, is a significant health concern.
The virus spreads to humans through contact with the bodily fluids of infected bats, pigs, or individuals, and there is currently no available vaccine. The confirmed cases have prompted a nationwide alert, with local residents undergoing quarantine measures. The infected individuals are both nurses at Narayana Multispeciality Hospital in Barasat, located 16 miles from Kolkata, raising concerns about potential undetected spread of the disease.
Narayan Swaroop Nigam, Principal Secretary of the Health and Family Welfare Department in West Bengal, confirmed the cases, stating that one of the nurses is in critical condition. The nurses worked together from December 28 to 30 before falling ill with high fevers and respiratory issues, leading to their admission to the hospital’s intensive care unit on January 4, with one in a coma.
Authorities suspect that the nurses contracted the virus while treating a patient who exhibited severe respiratory symptoms and subsequently passed away before being tested. Contact tracing efforts are underway to identify individuals who had contact with the nurses and the deceased patient, with 180 people tested and 20 high-risk contacts placed in quarantine.
“All tested individuals are asymptomatic and have tested negative. They will undergo further testing before the completion of their 21-day quarantine period,” added Mr. Nigam. The Ministry of Health and Family Welfare in India has issued a countrywide alert, emphasizing the importance of preventive measures such as enhanced surveillance to contain any potential spread.
Recognizing the severe threat posed by the Nipah virus, the World Health Organization has classified it as a critical research priority. The virus has a fatality rate of up to 85% and presents with initial symptoms like fever, headaches, pain, vomiting, and sore throat, progressing to fatal brain inflammation. Transmission occurs through contact with infected animals, contaminated food, or direct person-to-person contact.
Oxford University is currently conducting phase one trials of its Nipah vaccine after promising initial results. Experts have warned about the increasing risk of Nipah virus outbreaks due to heightened human interaction with fruit bats, particularly as they move into densely populated areas. The virus was first discovered during an outbreak among pig farmers in Malaysia in 1999 and has since remained a persistent threat.
Originating in Bangladesh in 2001, the Nipah virus has reemerged almost annually, with evidence of the pathogen found in fruit bat populations across various countries, including Cambodia and Thailand.
