Two cases of the highly contagious Nipah virus have been confirmed in a hospital in West Bengal, India. Close to 200 people were also exposed to the zoonotic virus. As a result, several Asian countries have instituted Covid 19–era airport screenings to monitor the spread of an infection for which there’s currently no vaccine or cure.
This deadly disease originates from direct contact with infected animals — mainly flying fox bats and pigs — or their contaminated tissues and secretions. Nipah can spread easily from person to person through contact with bodily fluids and cause minor to severe infections. It has a fatality rate of between 40% and 70%.
Those infected are “typically sick for 3 to 14 days with fever, headache, cough, sore throat and difficulty breathing,” said the Centers for Disease Control and Prevention. In more severe cases, people may experience “brain swelling (or encephalitis),” which can lead to coma in 24 to 48 hours.
The virus was first discovered in 1999. Since then, outbreaks have “occurred almost annually in Asia, particularly in Bangladesh and India,” between December and April, said The Washington Post. But this outbreak is West Bengal’s first since 2007.
India has “ensured timely containment” of the cases through “enhanced surveillance, laboratory testing and field investigations,” the Indian Ministry of Health said in a statement. And while no official cases have been identified outside of India, countries including China, Indonesia, Malaysia, Nepal and Thailand have taken preventative measures. Airports are performing “health declarations, temperature checks and visual monitoring for arriving passengers,” said The Associated Press. |
