The latest trends

The Contra Costa Health Services announces new cases and deaths each day, though bottlenecks in testing and reporting lags can introduce delays.

Experts say the true number of people infected is unknown and likely much higher than official tallies.

Cumulative cases by day

Over the past week, the county has averaged 176 new cases and 0.7 new deaths per day. The number of confirmed infections is currently doubling every 81.9 days.

The lines above are seven-day averages. They offer a more stable view of the trend than daily totals. That's why experts wait for lines like these to flatten before they say conditions are improving.

State and local officials are closely watching the latest figures as they weigh when and how to reopen. Over the last seven days, officials have reported 1,232 new cases, which amounts to 109 per 100,000 residents.

Hospitals and patients

Lockdown measures aim to slow the virus in hope of preventing hospitals from being overrun.

To keep tabs on capacity, officials watch out for rapid increases in the number of confirmed COVID-19 patients.

Intensive care and other hospitalized patients
California Department of Public Health

There are now 70 patients admitted to county hospitals with a confirmed case of COVID-19, according to the latest figures from the state. Of those, 24 are in an intensive-care unit.

Officials also closely monitor the number of beds open in intensive-care units. In late July, the state changed its tracking method to exclude beds that are only for infants from the count.

There are currently 37 staffed and available beds in Contra Costa County according to the latest government data.

Nursing homes

Nursing homes have become a tragic focal point of the coronavirus outbreak. California's Department of Public Health has listed 45 skilled nursing and assisted-living facilities in Contra Costa County that have reported COVID-19 cases.

The state last updated the list on November 20. Officials withhold the precise number where there are 10 or fewer cases. The numbers reflect cumulative counts.

Reopenings and restrictions

Gov. Gavin Newsom’s reopening system classifies counties into four tiers based on metrics developed by state officials. Which tier a county falls in determines what can be reopened.

Contra Costa County is currently in Tier 1, which keeps schools and most nonessential businesses closed.

Tier 1

Widespread

Most nonessential indoor business operations are closed

Tier 2

Substantial

Some nonessential indoor business operations are closed

Tier 3

Moderate

Some business operations can open with modifications

Tier 4

Minimal

Most business operations can open with modifications

The state is now using three statistics to judge counties. With some exceptions, metrics must surpass the benchmark for the next tier in order to loosen restrictions. The latest numbers, along with tier reassignments, are released each Tuesday.

The first is called the adjusted case rate. It takes new cases in a recent seven-day period — excluding cases at prisons and jails — and adjusts for population. In some areas, that number is modified to account for the volume of testing. Contra Costa County's most recent adjusted case rate was 10.

The second metric is the positive test rate, which is the percentage of tests for the virus that come back positive. Contra Costa County's most recent positive test rate was 3.7%.

The third metric measures whether positive tests in the most disadvantaged neighborhoods have significantly exceeded a county's overall rate — a disparity that's been widespread during the pandemic. The statistic is known as the Healthy Places Index. Citing the strain of the recent surge in cases, the state has paused its use.

Based on its current tier in the state framework, here’s what is allowed to open in Contra Costa County.
