Sacramento County has established a COVID-19 dashboard, providing more detailed breakdowns and infographics showing the area’s confirmed coronavirus cases and fatalities.

As of 11 a.m. Tuesday, the county had reported 816 lab-confirmed cases of the virus and 28 fatalities. The increase of 77 new cases over the previous day appears to be the largest one-day jump recorded so far.

The new dashboard includes counts for infection and death totals; a chart showing the increase in cases by day; a map of coronavirus cases by ZIP code; and breakdowns of case totals by age group, sex, race/ethnicity and geographic location, all on one webpage.

As of early Monday, race or ethnicity was known for 528 of the 816 reported cases (about 65 percent), and more than half of the patients, 295 of them, were white. About 11 percent of known cases were reported as Asian, 9.8 percent were black, 9.3 percent were Hispanic and the remaining 14 percent were “other/multiple races.”

According to U.S. Census Bureau estimates for July 2019, Sacramento County’s population is about 44 percent white alone, 23 percent Hispanic or Latino, 17 percent Asian alone, 11 percent black alone and 6.4 percent two or more races. The county has a population of more than 1.5 million people.

Of total cases, close to one-third are elderly. A total of 31 percent of confirmed infections have come in patients 65 or older, nearly 25 percent in patients between 50 and 64, and 44 percent in adults age 18 to 49. A tiny proportion, just 1 percent, have been juveniles, the county says.

Male patients make up 46 percent of confirmed cases in Sacramento County, compared with 54 percent for females.

A bar chart of confirmed cases shows a steady rise in cases since early March that only recently showed signs of flattening in the past few days: Sacramento County had 719 confirmed cases last Thursday, 733 on Friday, 738 Saturday and 739 as of Sunday.

But that chart, which the county says will be updated every Monday and Thursday, does not yet reflect Tuesday’s jump of 77 cases, which would be the biggest one-day increase in cases by volume on that chart, representing a 10.4 percent increase from the 739 cases reported Monday.

The county’s 28 deaths are broken down only by geographic location, but not by ZIP code. Fourteen have died so far inside Sacramento city limits, three in Elk Grove, two in Citrus Heights, one in Rancho Cordova and eight in unincorporated areas.
