Indian officials report they have managed to control a Nipah virus outbreak in West Bengal, where two confirmed cases have emerged. This has prompted multiple Asian nations to enhance health screenings and monitor travelers arriving from India.
On Tuesday, India’s Ministry of Health indicated that the two cases were detected since December and that all known contacts have been isolated and tested.
While the ministry hasn’t shared specific details about the patients, they confirmed that tracing of 196 contacts has been finalized, with all testing coming back negative.
“We are continuously monitoring the situation, and all necessary public health measures are in place,” the ministry stated.
The Nipah virus is zoonotic and was first identified in Malaysia during the 1990s. It spreads through fruit bats, pigs, and can also be transmitted from person to person.
Currently, there is no vaccine available for this virus, which can lead to severe symptoms like fever, convulsions, and vomiting.
The focus is on supportive care to manage complications and keep patients comfortable.
The WHO estimates the fatality rate of Nipah virus to be between 40% to 75%, which is significantly higher than that of the coronavirus.
So far, there haven’t been any reported cases outside of India; however, nations across Asia are increasing precautionary measures at airports.
Countries like Indonesia and Thailand have intensified screening protocols, including health declarations and temperature checks for incoming travelers. Additionally, Thailand’s Ministry of Disease Control has installed a thermal scanner at Bangkok’s Suvarnabhumi Airport for flights coming from West Bengal.
Myanmar’s Ministry of Health has suggested that citizens avoid non-essential travel to West Bengal and urged anyone who develops symptoms within two weeks of visiting to seek medical advice promptly.
They mentioned enhancing fever surveillance for passengers arriving from India and ensuring clinical testing capabilities and medical supplies are readily available.
Moreover, Vietnam’s Ministry of Health is advocating for strict food safety practices and has instructed local authorities to increase surveillance at borders, medical facilities, and communities, as per local reports.
China is also ramping up its epidemic prevention efforts in border areas, with reports indicating that health authorities are conducting risk assessments, offering training for medical staff, and bolstering surveillance and testing capabilities.
Past Nipah outbreaks in West Bengal occurred in 2001 and 2007, but most recent cases have been primarily reported in Kerala, where a significant outbreak in 2018 resulted in at least 17 fatalities.
