Regional Alert Sparks Strict Travel Measures
Pakistan has mandated strict health screening for all travelers at every entry point into the country, following the confirmation of two Nipah virus cases in India’s West Bengal state. The Ministry of National Health Services stated that no individual will be allowed entry without clearance from Border Health Services–Pakistan.
Enhanced Surveillance at All Points of Entry
The ministry’s advisory, issued in response to a regional alert from the WHO, calls for 100% screening of all passengers, transit travelers, crew, and support staff at international airports, seaports, and land crossings. The measures include:
- Mandatory verification of country of origin and 21-day travel history for all nationalities.
- Thermal screening and clinical assessment for symptoms like fever, headache, and respiratory issues.
- Special attention for travelers from or transiting through Nipah-affected areas.
Suspected cases will be isolated and managed under strict infection control protocols, with affected areas disinfected immediately.
High-Risk Pathogen with No Cure
The Nipah virus is classified by the World Health Organization as a priority pathogen due to its high fatality rate of 40% to 70% and the absence of an approved vaccine or cure. The virus spreads primarily from infected animals, like fruit bats, to humans, and can also transmit between people.
Regional Nations on High Alert
Authorities in Singapore, Hong Kong, Thailand, and Malaysia have also implemented urgent screening measures, including airport temperature checks, to prevent the virus from spreading beyond India. These steps highlight regional concern over the epidemic-prone virus.
Understanding the Nipah Threat
First identified in Malaysia in 1999, Nipah virus outbreaks have occurred almost annually, primarily in Bangladesh and India. While human-to-human transmission is possible, it is not easily sustained, typically leading to small, contained outbreaks. Scientists note the virus has a long incubation period, which can make airport screening challenging.
Several candidate vaccines are under development, including one in Phase II trials in Bangladesh, but none are yet approved for public use. The new border controls in Pakistan will remain in force until further notice, with daily reports sent to the National Command and Operation Centre.
