Nipah virus is a zoonotic virus which is transmitted from animals to humans. Contaminated food and direct contact with an infected individual can lead to human-to-human spread. It can also cause illness in pigs. It was first identified during an outbreak in Malaysia in 1998-1999, the virus can spread to humans through direct contact with infected bats, pigs, or contaminated fruits, as well as through human-to-human transmission. Initial symptoms include fever, headache, and muscle pain, progressing to severe respiratory and neurological issues such as encephalitis. With a high mortality rate and no specific antiviral treatment or vaccine, prevention focuses on avoiding exposure to potential sources of infection and implementing public health measures. Read on as we list the signs, causes, treatment and prevention tips for the Nipah virus.
Symptoms of Nipah virus
Symptoms of Nipah virus can be classified into three categories:

According to the World Health Organisation, some people can also experience severe respiratory issues and atypical pneumonia. In severe cases, encephalitis and seizures can occur, progressing to coma.
Incubation period
The onset of symptoms can start from 4 to 14 days after getting infected. In some cases, the incubation period can also be as long as 45 days.
