Singapore is introducing temperature screening at its airports for passengers arriving from places affected by the Nipah virus, the Communicable Diseases Agency (CDA) said on January 28.
The agency also said it will step up checks on migrant workers coming from South Asia, though no Nipah cases have been found in Singapore so far. The virus, which has no vaccine or cure, was recently detected in two people in India’s West Bengal state, with one of them in critical condition. This is India’s seventh Nipah outbreak since 2001.
CDA said travellers entering Singapore will get health notices advising them to seek medical help if they feel unwell and to follow safety guidelines. The agency is also working with health officials in South Asia and helping to set up a global system for sharing genetic data from detected cases.
Local hospitals have been told to look out for anyone showing Nipah symptoms, especially patients who recently travelled to affected areas. CDA said more health measures could be introduced if the risk level goes up.
Health Minister Ong Ye Kung urged the public to stay alert in a Facebook post. He said that while the Nipah virus can spread between people in close contact, it is much less contagious than viruses such as SARS or COVID-19. “We must always be prepared, as deadly outbreaks can happen anywhere,” he added.
Other countries in the region are also taking precautions. Thailand has started screening travellers from high-risk areas and increasing health surveillance. Taiwan plans to label Nipah as a Category 5 disease, its highest alert level, while Malaysia continues to maintain border health checks and follow updates from the World Health Organization (WHO).
The Nipah virus mainly spreads from bats or infected animals like pigs and dogs. Human infection can happen through direct contact or contaminated food. The WHO says the virus can be deadly — with fatality rates between 40 and 75 percent — and causes symptoms ranging from mild illness to severe brain infection.
Experts say the virus spreads slowly, as human-to-human transmission is rare. Dr. Leong Hoe Nam explained that most cases come from contact with infected animals. “The problem is that there’s no specific treatment for Nipah,” he said. Care usually focuses on managing serious symptoms like seizures or coma.
The Nipah virus was first identified in 1998–1999 during an outbreak among pig farmers in Malaysia and Singapore, which caused nearly 300 infections and more than 100 deaths. Close to a million pigs were killed to stop the spread.
