Currently, there are no specific drugs or vaccines for the Nipah virus, which at its worst sees people ending up in a coma within 24 to 48 hours, and up to 20% may develop residual neurological issues such as seizures and personality changes.
Onset symptoms include a fever, headaches, muscle pain, vomiting, and a sore throat. In more severe cases, patients may experience severe respiratory problems
The Nipah virus is commonly spread from animals, contaminated food, and human-to-human transmission.
Officials say it's important to take the necessary measures to prevent contamination by practising proper hygiene, avoiding contact with someone infected, and wearing proper clothing when handling ill animals, and that most people make a full recovery from the virus.
