Nipah virus (NiV) is a zoonotic virus which transmits from animals to humans and can also spread from person to person. It was first identified in 1999 during an outbreak in Malaysia and Singapore. The virus is named after the village of Sungai Nipah in Malaysia, where the initial outbreak occurred.

Key facts about the Nipah virus:
The Nipah virus is primarily transmitted to humans from animals, particularly fruit bats (flying foxes), which are considered the natural reservoir of the virus. Any human can get infected by directly contact with infected bats, their saliva, urine, or faeces, or consuming fruits partially eaten by infected bats. Transmission from one human to anothers can occur when connecting directly with the bodily fluids of infected individuals.
Nipah virus infection can cause various symptoms, including fever, headache, drowsiness, disorientation, and confusion. In some of the severe cases, it can lead to encephalitis (inflammation of the brain), seizures, and a high mortality rate, with death occurring within a few days to a few weeks after symptom onset.
Nipah virus outbreaks have occurred primarily in South and Southeast Asia, including Malaysia, Bangladesh, and India. These outbreaks are often associated with consuming contaminated food or close connection with infected animals or or drinks.
It is believed that there is no specific antiviral treatment for Nipah virus infection. Prevention measures focus on avoiding contact with infected animals and practising good hygiene, such as washing hands thoroughly and avoid consuming raw date palm sap, which can be contaminated with the virus.
Research on the Nipah virus continues to understand its transmission dynamics, develop diagnostics, and explore potential treatments and vaccines.
Because of the high mortality rate, Nipah virus is considered a significant public health concern. It is highly potential for human-to-human transmission, and the lack of specific antiviral treatments. Health authorities and researchers in affected regions closely monitor and respond to outbreaks to limit the spread of the virus.
