Startling state figures released Saturday show 34 nursing homes in seven Bay Area counties have confirmed cases of coronavirus.

Gateway Care and Rehabilitation Center in Hayward has 102 such cases, with 33 staff members and 69 patients infected, significantly higher than the 68 total coronavirus cases reported by Alameda County on Thursday, which included 13 deaths, according to a partial list the state health department made newly public.

The list also includes Valley House Rehabilitation Center in Santa Clara, with 63 confirmed cases, and is comprised of 86 percent of nursing facilities that reported their data within the last day. Of the 1,224 skilled nursing facilities in California, 261 have reported one or more COVID-19 cases by either a resident or staff member as of Friday.

“Even these shocking numbers are likely an undercount because the state still relies on reporting by facilities, which has been spotty at best,” said Mike Dark, a staff attorney at California Advocates for Nursing Home Reform. “The staggering death counts we will see over the next few weeks are going to reveal that these numbers are the tip of the iceberg.”

The available state data does not include deaths or exact figures for the number of infected patients and staff at most nursing facilities. It also is limited to nursing homes and does not include assisted living and other types of care facilities.

According to state health officials, the list is based on “point in time data from all the locations who reported in the last 24 hours.”

“This is not a comprehensive list from the January until now,” state officials said in an email, noting also that it does not include those where patients have been transferred to hospitals. “We are working with (skilled nursing facilities) on a reporting system that will ensure we can publicly report 100 percent of the facilities in the coming days.”

The list also does not break down specific numbers for nursing homes that have less than 11 positive cases among either healthcare workers or residents.

Los Angeles County’s nursing facilities make up the majority of the cases, with at least 148 facilities that have infections, including a facility called Brier Oak on Sunset, which has 142 confirmed cases, according to the state.

The state lists 11 Santa Clara County nursing homes with infections — the most in the Bay Area. Most of the names had not been made public by the county.

Contra Costa County health officials have identified 14 facilities with positive cases, for which the state list does not account. At the Orinda Care Center, health officials have confirmed 53 positive cases among staff and residents and four deaths. At Carlton Senior Living, five patients have died among the 35 who tested positive for COVID-19, and 23 staff members have contracted the virus.

The county would not identify the other 12 facilities, but said they have positive tests for two residents and 10 staff among those nursing homes.
