"Ebola is an RNA virus, which means it mutates once or twice every time it copies itself. This could change the way the virus operates when inside the human body."
"Ebola does share some of the characteristics of airborne viruses like influenza and we should not disregard the possibility of it evolving into something that could be transmitted in this way," added Sanders, whose work on Ebola led to his participation in the U.S. Defense Threat Reduction Agency's Biological Weapons Proliferation Prevention Program.
"I want the facts to be clear. It's important that we not get the idea that this can't happen," he added. "When people say that it is impossible for this virus to mutate, this is simply not true."
To pose a major threat in the U.S., the Ebola virus would have to mutate so that it could survive outside the body for a significant length of time like influenza can, Sanders said.
"This is not how the Ebola virus is currently known to spread, but there is evidence that it has some of the necessary components for respiratory transmission," he said.
