The Nipah virus outbreak refers to the spread of a viral infection first identified in Malaysia in 1998. The virus is transmitted from animals, particularly fruit bats, to humans, often through contaminated food or direct contact with infected animals. Symptoms can range from mild flu-like signs to severe respiratory issues and encephalitis. Outbreaks have occurred in several countries, including India and Bangladesh, leading to significant public health concerns. There is currently no specific treatment or vaccine for the Nipah virus, making prevention and control measures crucial in affected regions to limit transmission and protect communities.
