Multiple federal agencies, in addition to the Centers for Disease Control and Prevention, are contributing resources to respond the coronavirus outbreak.
For instance, the Department of Homeland Security's Countering Weapons of Mass Destruction office is facilitating airport screenings, according to a DHS official.
Additionally, Customs and Border Protection has measures in place to identify travelers with overt signs of illness, who may be potentially infected with a communicable disease. And the CDC provided signage to the Transportation Security Administration for placement at airports warning travelers of risks associated with travel to certain areas in China, according to a TSA official.
The US Coast Guard and Federal Emergency Management Agency and US Citizenship and Immigration Services are also involved, according to DHS.
Acting Homeland Security Secretary Chad Wolf said Wednesday the department will continue to adapt as the virus changes and adapts.
According to a Federal Aviation Administration official, who referred CNN to the CDC and State Department, said the agency's responsibility is to ensure that planes get safely from one point to another. The agency is not involved with passengers coming in and out of the US.
But airline personnel are keeping a close watch.
The Allied Pilots Association — the union that represents Delta and United pilots — said it is updating pilots regularly with current information and has provided them with specific precautions they can use to mitigate any risk, according to Communications Director Gregg Overman.
"This is obviously a rapidly developing situation, so we may have more to report in the coming days," he added.
