After consultation with HHS, the State Department decided to allow them on board, but isolated them from the other passengers. "These individuals were moved in the most expeditious and safe manner to a specialized containment area on the evacuation aircraft to isolate them in accordance with standard protocols," it said. "During the flights, these individuals will continue to be isolated from the other passengers." All passengers were being closely monitored throughout the flights. "Any who become symptomatic will be moved to the specialized containment area, where they will be treated," the statement said. The first flight is due to land shortly at a US Air Force base in California, where all passengers will undergo 14 days quarantine, while a second plane is heading to another base in San Antonio, Texas. More than 600 people are already in quarantine in the United States, evacuated earlier from the virus epicenter in the Chinese city of Wuhan, the Centers for Disease Control and Prevention said on Friday.
