The Ebola virus becoming airborne is a possible but unlikely outcome in the current epidemic, Centers for Disease Control and Prevention (CDC) Director Tom Frieden said Tuesday.
The outbreak involves Ebola Zaire, a strain that is passed through bodily fluids, not the air. But some experts have expressed fear about viral mutations due to the unprecedented — and rising — number of Ebola cases.
Frieden sought to allay those fears during a call with reporters.
“The rate of change [with Ebola] is slower than most viruses, and most viruses don’t change how they spread,” he said. Frieden is unofficially spearheading the U.S. response to Ebola.
