The additional health screenings will start at JFK on Friday night, but the CDC is also sending experts to airports in Los Angeles and San Francisco in hopes of preventing the spread of the mysterious coronavirus strain. There hasn't been a similar screening effort in the U.S. since the Ebola outbreak in 2014.

"This is a new disease and information is really rapidly evolving and we are continuing to learn about it day by day," said Dr. Nancy Messonnier of the Centers for Disease Control.

The focus will be on passengers on flights originating in Wuhan, China. So far, there have been 45 confirmed cases, and the disease has spread to Thailand and Japan, sparking a World Health Organization alert. Authorities believe it is rare for the virus to spread between humans.
