Two instances of Nipah virus, a rare bat-borne illness that served as the inspiration for the movie Contagion, have been identified at a hospital in India, with one patient currently in critical condition. This deadly infection is known to cause brain swelling and has no known vaccine.
The virus is typically transmitted to humans through contact with bodily fluids of infected bats, pigs, or individuals, leading to a nationwide alert in response to the confirmed cases. Both cases involved nurses at Narayana Multispeciality Hospital in Barasat, West Bengal, raising concerns about potential undetected spread of the disease.
Mr. Narayan Swaroop Nigam, Principal Secretary of the Health and Family Welfare Department in West Bengal, confirmed the cases, stating that two nurses from the hospital had contracted the Nipah virus, with one of them in critical condition. The nurses fell ill after working together and were admitted to the hospital’s intensive care unit, with one of them currently in a coma.
Authorities suspect that the nurses were infected while treating a patient who later died from severe respiratory symptoms before being tested for Nipah virus. Contact tracing efforts are underway, with 180 individuals tested and 20 high-risk contacts placed in quarantine as a precaution.
“All individuals tested so far are asymptomatic and have tested negative. We will conduct additional tests before their quarantine period ends,” mentioned Mr. Nigam. The Ministry of Health and Family Welfare in India has issued a nationwide alert, emphasizing the importance of surveillance and preventive measures to curb further transmission.
Recognizing the severity of the situation, the World Health Organization has designated Nipah as a critical research priority due to its potential to trigger a global health emergency. With a fatality rate of up to 85%, symptoms of Nipah virus infection include fever, headaches, pain, vomiting, sore throat, and ultimately progress to deadly brain inflammation.
Oxford University is currently in the initial phase of testing its Nipah vaccine following promising early results. Experts have cautioned about the increased risk of Nipah virus outbreaks due to greater human interaction with fruit bats moving into densely populated areas. Originally discovered during a 1999 outbreak among pig farmers in Malaysia, the Nipah virus remains a persistent threat worldwide.
The virus first surfaced in Bangladesh in 2001 and has reappeared almost annually since then. Fruit bat populations in various countries, from Cambodia to Thailand, have been found to carry this dangerous pathogen, highlighting the ongoing global concern regarding Nipah virus outbreaks.
