Tulare County health officials reported Tuesday that 47 people have tested positive for COVID-19 at Redwood Springs Healthcare Center, a Visalia nursing home, where one person has died.

One individual is being treated at a hospital, and the rest are in isolation at the healthcare center.

A week ago, the Tulare County Department of Health said that six patients and two healthcare workers had tested positive for the virus at Redwood Springs.

Coronavirus Spikes at Other California Nursing Homes

Similar spikes in positive tests are being seen at nursing homes throughout California.

Coronavirus infections reported at a nursing home in the Bay Area increased to nearly 50 from 27 last week and one infected person has died, officials said.

At Orinda Care Center, 27 residents and 22 staff members have tested positive for the virus. Four residents have been hospitalized while the rest remained at the facility, according to officials at Contra Costa Health Services.

One person in hospice care at the facility who had tested positive for COVID-19 died over the weekend, a health department spokesman said.

Health officials began investigating the outbreak last week after two staff members sought medical care for coronavirus symptoms. By Friday, test results showed 24 residents and three employees were infected, the East Bay Times reported Tuesday.

More Tests Needed at Nursing Homes

Outbreaks at nursing homes and elder residences have alarmed experts.

Mehrdad Ayati, a doctor of geriatric medicine who teaches medicine at Stanford University, said he and his colleagues have been very worried about the vulnerable populations in nursing homes.

“We need to be massively testing the skilled nursing facilities. … These are going to be the people overwhelming the acute care centers,” Ayati told the East Bay Times. “Community hospitals will be overwhelmed. Then we’ll have a high number of mortalities.”

Elsewhere, at Canyon Springs Acute Care in San Jose, the number of infections among patients and staff jumped from 11 to 20 since Friday, with 16 people awaiting test results, the newspaper reported.

In Yucaipa in San Bernardino County, eight nursing home residents were hospitalized in a coronavirus outbreak that infected nearly 60 people and killed two of them, officials said last week. Six staff members also tested positive for the virus.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough, that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia and death.
