Read the airport's statement:
The Centers for Disease Control and Prevention (CDC) is now conducting enhanced passenger screening at Detroit Metropolitan Wayne County Airport, in response to concerns regarding the Coronavirus. The Airport Authority is working with the CDC, U.S. Customs and Border Protection (CBP), our airline partners and tenants to help prevent the spread of the virus.
In the McNamara Terminal, Detroit Metropolitan Airport offers direct flights to and from Beijing and Shanghai, China. Out of an abundance of caution, the janitorial service has increased the frequency of its cleaning schedule in the terminal’s Federal Inspection Station, also known as the International Arrivals area.
The Airport Authority will remain in communication with the CDC and provide updates when possible.
