All you want to know about the Nipah virus... and what is the secret of its spread with bats?


Nipah virus is not a newly discovered virus and it was successfully contained in the past, but the emergence of the corona virus created fear of any zoonotic disease in people's minds, since samples of Nipah virus were discovered in two species of bats in India, there has been curiosity about this disease Since some foreign dailies have suggested that Nipah is more deadly than Corona, concerns have been raised about the extent of Nipah virus disease.


According to a report in the Times of India, the deadly Nipah virus was detected in two species of bats in the Indian state of Maharashtra for the first time by scientists from the Pune-based National Institute of Virology (NIV). In March 2020.


Q: Why are virologists on alert?


A: Dr. Pragta Yadav of the Indian National Institute of Virology said that none of the bat species in Maharashtra had previously shown any exposure to the Nipah virus, and it is also known that Nipah is considered dangerous, as there is no medicine or vaccines and the death rate among the infected is high. While the case fatality rate (CFR) among patients infected with MERS-CoV ranges between 1-2%, the case fatality rate for Nipah ranges from 65-100%.

Q: Has there been an outbreak of Nipah disease in the past?

A: The Nipah virus is on the watch list of the WHO's Top 10 Pathogens List Bangladesh, Malaysia, India and Singapore are the countries where the outbreak has occurred. It was first identified in Malaysia in 1998-1999 during an encephalitis-like outbreak among pigs and pig breeders. Case fatality rate at 40% At that time, in India, there were four outbreaks of Nipah with a CFR of 65-100%.


In 2001 in Siliguri district, West Bengal.


2007 in Nadia District, West Bengal.


2018 in Kozhikode district of Kerala, with 18 deaths.


2019 in Kozhikode again.


All about Nipah virus:

According to the US CDC website, Nipah virus (NiV) is a zoonotic virus, which means it can spread between animals and humans.


Q: What are the symptoms of Nipah virus?

Infection with NiV is associated with encephalitis (swelling of the brain) and can cause mild to severe illness and even death Symptoms usually appear within 4-14 days after exposure to the virus At first one or more of the following symptoms may be seen: fever, headache, cough Sore throat, difficulty breathing, vomiting.


This may be followed by severe symptoms such as:

Confusion or drowsiness, seizures, coma, swelling of the brain (encephalitis), death may occur in 40-75% of cases. Long-term side effects in survivors include persistent convulsions and personality changes, and in some cases latent or latent infections have also been reported months and even years after exposure.


Q: What are the preventive measures against this virus?



The CDC says areas where outbreaks are occurring should ask people to take the following steps:


Wash hands regularly with soap and water.


Avoid contact with bats or sick pigs.


Avoid areas where bats are known to perch.


Avoid eating fruits that may be contaminated with bats.


Avoid contact with blood or body fluids of anyone known to be infected.
