Indian authorities have declared a recent outbreak of the deadly Nipah virus contained, as several Asian countries step up health screening for travellers arriving from India. Indonesia and Thailand have increased screening at major airports, including health declarations, temperature checks and visual monitoring of passengers arriving from India. Malaysia also confirmed the introduction of health screening at international ports of entry. Nipah virus is a zoonotic disease transmitted through fruit bats, pigs and human-to-human contact. First identified in Malaysia in the late 1990s, Nipah has since caused outbreaks in Bangladesh, the Philippines and India.
