Changi Airport Intensifies Health Measures After India Reports Nipah Cases
Global Health Authorities Enhance Screening Measures Amid Nipah Virus Outbreak in India
A recent outbreak of the deadly Nipah virus in India has prompted several countries to implement stricter health screening measures at their airports. The virus, which is primarily transmitted through fruit bats and other animals such as pigs, can lead to severe symptoms like fever and brain inflammation. It carries a fatality rate ranging from 40% to 75%, making it one of the most dangerous viral infections.
Although the virus can spread between humans, transmission typically requires prolonged close contact with an infected individual. More commonly, humans contract the virus through direct contact with infected bats or by consuming fruit contaminated by them. This mode of transmission underscores the importance of monitoring both animal populations and human activities in high-risk areas.
The cases in India were confirmed in late December, sparking concerns among neighboring countries. Despite the severity of the virus, virologists have emphasized that the risk to the general population remains low. Several vaccines are currently in development but are still undergoing testing. Experts stress the need for continued vigilance while maintaining public confidence.
International Response to Nipah Outbreak
In response to the outbreak, Thailand, Singapore, Hong Kong, and Malaysia have all taken proactive steps to prevent the spread of the virus. These measures include enhanced airport screenings, temperature checks, and health declarations for travelers arriving from affected regions.
Singapore's Communicable Diseases Agency announced that it will implement temperature screening at Changi Airport for flights coming from areas impacted by the Nipah outbreaks in India. The agency also stated that it is working with South Asian counterparts to better understand the situation and is developing a global platform for reporting genome sequencing data of detected cases.
Hong Kong has also increased its health screening procedures at Hong Kong International Airport. Passengers arriving from India must undergo temperature checks at the gates, while the airport authority facilitates these measures in coordination with the health department.
Thailand has introduced designated parking bays for aircraft arriving from regions affected by the Nipah virus. Additionally, passengers are required to complete health declarations before clearing immigration. Malaysia has followed suit, increasing health screening at international ports of entry, especially for arrivals from high-risk countries.
China’s disease control authority has confirmed that no Nipah infections have been detected within the country. However, they have acknowledged the potential risk of imported cases, as reported by state broadcaster CCTV. Similarly, Nepal, which shares a busy border with India, has placed itself on "high alert" and has intensified screening for travelers.
Containment Efforts in India
In the eastern Indian state of West Bengal, two individuals were infected with the Nipah virus in late December. Both are health workers currently under treatment at a local hospital. According to a district health officer, authorities have traced 196 contacts linked to the two cases, with none showing symptoms and all testing negative for the virus.
The Indian health ministry issued a statement clarifying that speculative and incorrect figures about Nipah virus disease cases are being circulated. They emphasized that enhanced surveillance, laboratory testing, and field investigations have ensured timely containment of the cases.
Historical Context of Nipah Virus
Nipah is not a new threat to India. It was first identified over 25 years ago during an outbreak among pig farmers in Malaysia and Singapore. Scientists believe the virus has existed in flying foxes, or fruit bats, for thousands of years. The World Health Organization (WHO) classifies Nipah as a priority pathogen due to its high fatality rate, lack of licensed vaccines or treatments, and the fear that it could mutate and become more transmissible.
India regularly reports sporadic Nipah infections, particularly in the southern state of Kerala, which is considered one of the world’s highest-risk regions for the virus. Since its emergence in 2018, the virus has been linked to dozens of deaths in Kerala. Bangladesh also experiences regular cases of the virus.
As of December 2025, there have been 750 confirmed Nipah infections globally, resulting in 415 deaths. The Coalition for Epidemic Preparedness Innovations is funding a vaccine trial aimed at preventing future outbreaks. The recent cases in West Bengal mark the state's first occurrence in nearly two decades, following five fatal infections in 2007.
