A St. Louis-area woman who recently traveled to Italy is Missouri's first confirmed coronavirus case, officials said Saturday.

The woman is in her 20s and is at home with her parents, St. Louis County Executive Sam Page, a physician, said during a news conference with Gov. Mike Parson. She was returning home from Italy when she showed symptoms.

She was tested at Mercy Hospital St. Louis, and officials said the hospital made sure that she was kept away from other patients.

Page said the woman and her parents assured officials that they have not left the home other than to go the hospital since she started to show symptoms a few days ago. The parents are not showing symptoms, he said.

“They're at home now,” Page said. “The patient followed all the proper procedures.”

The Missouri announcement came the same day that neighboring Kansas confirmed its first case of the virus that causes COVID-19, a woman from the Kansas City area under 50 who traveled to the Northeast.

Their announcements also came as Florida reported two coronavirus deaths, the first outside the West Coast. The total U.S. death toll reached 19.

The number of U.S. coronavirus cases swelled to 400, with cases in about half of the states. Indiana, Minnesota, Nebraska and Pennsylvania also recently reported their first cases.
