‘The Nipah virus is making news again after tragic reports that a 12-year-old boy died from the virus on Sept. 5 in Kerala’s Kozhikode district. He had been admitted to a private hospital after running a high fever and showing symptoms of encephalitis…
The World Health Organization classifies (Nipah) as a “virus of concern” for future epidemics because “each year it spills over from its animal reservoir into humans,” says Dr. Stephen Luby, a professor of infectious disease at Stanford University. And when humans are infected, it can be transmitted from person to person.
But the virus is not as transmissible as some other viruses. “There are occasional Nipah superspreaders who infect a lot of people,” says Luby. “But the average transmission rate is less than one person per infection.
“However, each time a person is infected, the virus is in an environment that selects for human adaptation and transmissibility. The risk is that a new strain that is more efficiently transmitted person to person could generate a devastating outbreak. Indeed, since 70% of people who are infected with Nipah virus die, such a strain could represent the worst pandemic humanity has ever faced.”…’
