Nipah virus sparks travel alert in Asia – 10 things to know about deadly virus
Travelers to parts of Asia are being warned of a potential health risk following reports of Nipah virus infections in humans. The UK Health Security Agency (UKHSA) has issued an alert, emphasizing the importance of awareness for those planning trips to affected regions in South and South-East Asia.
Understanding the Threat
Nipah virus is an animal virus that can infect people. While fruit bats are the natural hosts, the virus can also spread to other animals. Human infections typically occur through direct contact with infected animals or by consuming fruits or fruit products contaminated by infected bats.
Severity of Infection
The Nipah virus carries a significant risk, with an estimated mortality rate of 40 to 75% among those infected. The virus can cause a range of symptoms, beginning with flu-like illness or fever. More severe cases can develop into pneumonia and, critically, encephalitis – inflammation of the brain – and meningitis.
Even those who survive infection may experience lasting neurological complications, including seizures and personality changes. In rare instances, the virus can reactivate months or even years after the initial illness.
How the Virus Spreads
Person-to-person transmission is possible through close contact with an infected individual or their bodily fluids. The UKHSA notes that this has been documented in Bangladesh and India, often occurring within families or among caregivers.
Travel Recommendations
The UKHSA advises travelers to avoid contact with bats and sick animals. Consumption of raw or partially fermented date palm sap should be avoided, and all fruits should be thoroughly washed and peeled. Eating fruit found on the ground or partially consumed by animals is also discouraged.
When handling sick animals or during slaughter, travelers are urged to wear protective clothing and gloves. Maintaining good hand hygiene and avoiding close contact with anyone suspected of having the virus are also crucial preventative steps.
