Pakistan has ordered enhanced health screening at all entry points after India confirmed two Nipah virus cases in West Bengal, joining several Asian countries tightening airport controls.

Axar.az reports that Thailand, Vietnam, Singapore, Hong Kong, Malaysia and Indonesia have introduced temperature checks and monitoring, mainly for travelers from India.

Indian authorities insist there is no outbreak, saying all contacts tested negative and airport screening is unnecessary.

Nipah is rare but highly deadly, with no vaccine, though it does not spread easily between people.

What to know about the virus:

The World Health Organization has confirmed two Nipah virus cases in eastern India.

Nipah is a rare but extremely deadly zoonotic virus, killing more than half of those infected. It spreads mainly from fruit bats or pigs to humans, often through contaminated food, and can also pass between people through very close contact.

Symptoms begin with flu-like signs but can quickly progress to brain inflammation, coma, and death. There is no approved vaccine or specific treatment, and care is largely supportive.

Outbreaks occur almost every year in parts of South and Southeast Asia, especially Bangladesh and India, though overall case numbers remain very low worldwide.
