SAN DIEGO (AP) — Hundreds more people evacuated from the virus zone in China began arriving Friday at military bases across the U.S. to begin a two-week quarantine.

Federal officials did not immediately say how many people were aboard flights that landed in San Diego and San Antonio. Another plane from the Wuhan region of China, the center of the outbreak of the new coronavirus, was also due to arrive later Friday in Omaha, Nebraska.

Officials with the Centers for Disease Control and Prevention said Thursday that it was unlikely that arriving patients would show symptoms.

Earlier evacuation flights to California have brought people to March Air Reserve Base in Southern California and Travis Air Force Base between San Francisco and Sacramento.

All evacuees are being quarantined for 14 days and monitored for any signs of illness.

The new virus is in the coronavirus family that includes Middle East respiratory syndrome, or MERS, and severe acute respiratory syndrome, or SARS. It causes fever, cough, shortness of breath and, in severe cases, pneumonia. It has sickened more than 31,000 people and killed more than 600, virtually all in China.
