It can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers
. The Nipah virus was first recognized in 1999 during an outbreak among pig farmers in Malaysia. It has caused outbreaks in Bangladesh and nearly annual outbreaks have occurred in that country since. The disease has also been identified periodically in eastern India. The case fatality rate is estimated at 40% to 75% and can vary by outbreak depending on local capabilities for epidemiological surveillance and clinical management
