Here’s where Sacramento County COVID-19 cases grew the fastest in July

Reported COVID-19 cases roughly tripled in Sacramento County during the past four weeks, and several densely populated, economically disadvantaged areas were among the hardest hit, county data show.

There were about 9,300 reported COVID-19 cases in Sacramento County on Monday, up from about 3,100 four weeks prior. That’s the equivalent of almost 40 new cases per 10,000 residents.

Among ZIP codes with at least 10,000 residents, the highest rates of new cases were in 95632 (Galt), 95838 (Del Paso Heights), 95832 (Meadowview), 95823 (Parkway/Valley Hi) and 95815 (Old North Sacramento).

The lowest rates of new cases among ZIP codes with at least 10,000 residents were found in 95630 (Folsom), 95742 (Rancho Cordova/Anatolia), 95608 (Carmichael) and 95628 (Fair Oaks).

Eleven of the 15 ZIP codes in Sacramento County with the most new cases per capita also had poverty rates above 20%. None of the 15 ZIP codes with the fewest new cases per capita had poverty rates that high.

Some of the increase in COVID-19 cases is due to increased testing. But the percentage of tests returned positive rose from 5.6% in Sacramento County on June 25 to 8.6% on July 25, the latest county data show.
