Reports of Nipah virus infections in India have prompted several countries to tighten health screening at international airports. Authorities fear possible cross-border transmission following confirmed cases in West Bengal.
Health officials in West Bengal confirmed five Nipah virus cases on January 11. The infections were detected at a private hospital in the state. Among the infected were members of the hospitalโs medical staff.
Two nurses reportedly contracted the virus after treating a patient who later died. The patient showed symptoms consistent with Nipah virus infection. However, a confirmed diagnosis was made after exposure occurred.
As a precaution, authorities placed more than 100 close contacts under home quarantine. Medical teams are monitoring them closely for any symptoms. Surveillance efforts have increased across the affected areas.
Airports Increase Screening Measures
Several countries responded by strengthening airport health protocols. Thailand began enhanced screening for passengers arriving from Kolkata. Health checks are now mandatory at major international airports.
Direct flights from Kolkata to Phuket continue operating under strict monitoring. Passengers undergo temperature checks and symptom assessments upon arrival. Authorities aim to detect cases early.
Nepal has also tightened preventive measures at Tribhuvan International Airport. Officials increased monitoring along land border crossings with India. Health desks remain active for incoming travelers.
Taiwan continues to maintain a travel alert for India. Authorities advised travelers to remain cautious and observe health guidelines. Screening measures remain unchanged but alert levels stay active.
Understanding the Nipah Virus Threat
The Nipah virus was first identified in 1998. The initial outbreak occurred in Malaysia. The virus takes its name from the village where it was discovered.
Experts explain that Nipah virus transmission to humans remains rare. However, infection often occurs through food contaminated by fruit bats. The virus can also spread through close contact.
In rural regions, unprocessed date palm sap poses a known risk. Consumption of contaminated sap has caused infections in past outbreaks. Winter seasons increase exposure risks.
The World Health Organisation classifies the Nipah virus as highly dangerous. No approved treatment or vaccine currently exists. Early detection remains the primary defense.
Symptoms and Public Health Response
Initial symptoms include fever, headache, muscle pain, and vomiting. Some patients also develop sore throat and fatigue. In severe cases, neurological complications may appear.
The virus can cause brain inflammation, known as encephalitis. Such cases can become fatal. Mortality rates in past outbreaks ranged between 40 and 75 percent.
Some infected individuals may remain asymptomatic. However, they can still pose risks. Health authorities urge immediate medical attention for suspected symptoms.
Indiaโs health department advised the public to follow preventive measures. Officials urged people to avoid contaminated food and maintain hygiene. Surveillance and response teams remain active.
