MERS surges again, but pandemic jitters ease
Kai Kupferschmidt
The number of infections of the deadly Middle East respiratory syndrome virus surges again in Saudi Arabia, but scientists are less worried that the virus will cause a pandemic than they were 3 years ago. Still, many details about the virus discovered in 2012 and harbored by camels are unclear. New research suggests that many more people than previously thought may have been infected with no or little symptoms. The best way to protect people may be a camel vaccine, and experiments to test two candidate vaccines in camels have just been finished in the United States and Europe.
