A deadly virus called Nipah carried by bats has already caused human outbreaks across South and South East Asia and has “serious epidemic potential”, global health and infectious disease specialists said on Monday. The virus, identified in 1999 in Malaysia and Singapore, has sparked outbreaks with mortality rates of between 40% and 90% and spread thousands of kilometres to Bangladesh and India – yet there are no drugs or vaccines against it, they said. “Twenty years have passed since its discovery, but the world is still not adequately equipped to tackle the global health threat posed by Nipah virus,” said Richard Hatchett, chief executive of the CEPI Coalition for Epidemic Preparedness Innovations, which is co-leading a Nipah conference this week in Singapore. CEPI, a partnership between disease experts, and public, private, philanthropic, and civil organisations, was set up in 2017 to try to speed up the development of vaccines against newly emerging and unknown infectious diseases. Among its first disease targets is Nipah, a virus carried primarily by certain types of fruit bats and pigs, which can also be transmitted directly from person to person as well as through contaminated food. Within two years of being first discovered, Nipah had spread to Bangladesh, where it has caused several outbreaks since 2001. A 2018 Nipah outbreak in Kerala killed 17 people. “Outbreaks of Nipah virus have so far been confined to South and Southeast Asia, but the virus has serious epidemic potential, because Pteropus fruit bats that carry the virus are found throughout the tropics and sub-tropics, which are home to more than two billion people,” Hatchett said.
