A recent outbreak of the rare and highly lethal Nipah virus is prompting a public health response in West Bengal, India. The virus, first identified in Malaysia in 1997, has a disturbingly high mortality rate and can spread through close contact with infected individuals or contaminated food.Health officials are currently working to contain the cluster of cases detected near Kolkata, a densely populated metropolitan area, and are prioritizing contact tracing to limit further transmission.
A deadly outbreak of Nipah virus, believed to have originated in bats, is causing concern in West Bengal, India, a region near one of the country’s largest cities. The emergence of this virus highlights the ongoing threat of zoonotic diseases – those that jump from animals to humans – and the importance of robust public health surveillance.
Health officials in India are working to contain the virus after identifying five cases of the illness, according to reports from the Press Trust of India. The cases were detected in the vicinity of Kolkata, the third-largest city in India.
Immediate contact tracing and quarantine measures have been initiated in response to the outbreak. The Nipah virus is known to spread from animals – particularly bats and pigs – to humans, and can also be transmitted between people.
Three new infections were confirmed this week, including a doctor, a nurse, and another healthcare worker. Previously, two nurses – one male and one female – tested positive for the virus. Both worked at a private hospital in Barasat, and one of the nurses is currently in critical condition.
The critically ill nurse is reportedly in a coma and their condition deteriorated after treating a patient with severe respiratory problems. That patient died before testing could be completed. A total of 180 people have been tested, and 20 are currently under quarantine.
Fruit bats, common in both urban and rural areas across India, are known to be natural hosts for the virus.
NİPAH VİRÜSÜNÜN BELİRTİLERİ NEDİR?
Authorities have stated that initial symptoms may not be apparent in infected individuals, but acute respiratory issues can develop rapidly after the virus spreads. Symptoms include high fever, headache, muscle pain, vomiting, and sore throat.
Currently, there are no specific treatments or vaccines available for Nipah virus infection. In severe cases, the virus can cause inflammation of the brain and lead to coma within 24 to 48 hours. The mortality rate associated with the virus ranges from 40% to 75%.
