Six people on a cargo vessel in the San Francisco Bay were taken to local hospitals Monday after requesting medical help for coronavirus-related symptoms, according to the fire department.
In all, 19 of the 21 people on the ship reported having COVID-19 symptoms, the fire department said.
The six people who were transported to the hospital said they tested positive for COVID-19 on Saturday.
"None of the six that we currently have are exhibiting severe signs of COVID-19," San Francisco Fire Department Lt. Jonathan Baxter said. "They're all able to walk. They're all able to breathe comfortably. This is a very mild onset at this time."
The vessel originated from the Philippines, according to the fire department.
