Recently, news about the Nipah virus(NiV)has sparked widespread concern on social media.

Due to the high fatality rate of this virus and its multiple outbreaks,many netizens are worried that it will become the next global pandemic threat like COVID-19.

To help everyone understand this virus scientifically and rationally, I will provide an in-depth interpretation for you from the nature of the Nipah virus, its transmission routes, preventive measures, and its potential impact on our country.

What is the Nipah virus?

The Nipah virus is a highly lethal zoonotic virus, first identified in 1998 in a pig farmer near the Nipah River(Sungai Nipah)in Malaysia, which led to 265 infections, 105 deaths, and the culling of over 1.1 million pigs.

Research has found thatthe Nipah virus is mainly divided into two genetic lineages, named after their places of initial discovery:

Malaysian strain (NiV-M): Mainly outbreaks in Southeast Asia, with clinical manifestations mainly encephalitis, and human-to-human transmission is relatively rare.

Bangladesh strain (NiV-B):Mainly prevalent in Bangladesh and India.Compared to NiV-M, this strain shows greater genetic heterogeneity, is more likely to cause severe respiratory diseases, and has a significant increase in human-to-human transmission.
