Maricopa County topped 300 new virus cases for the second time this week Friday. County health department preliminary numbers showed 388 new COVID-19 cases and 10 new deaths Friday.

After a five day stretch last week where daily cases averaged 426 and a 12-day average of 308 cases a day, new cases numbers steeply declined, averaging just 65 new cases a day across three days Sunday through Tuesday. Cases spiked to 335 Wednesday, receded to 133 Thursday before jumping to the highest total of the week, 388, on Friday. The 10 deaths reported Friday were far lower than the week’s peak of 22 on Wednesday.

County cases and deaths have been returning to the levels they were at before the summer surge. COVD-19 cases peaked in the county in late June and early July, according to data from the Maricopa County Department of Public Health, reaching 3,825 cases in a day on June 29. In the most recent day of complete data, Sunday, Sept. 6, the county’s seven-day daily average was 250 cases, the lowest it’s been since May 28, just before the county’s surge.

The county’s surge in coronavirus-related deaths has lagged a couple weeks after the surge in cases, as is typical with COVID-19 reporting. The county’s worst single-day death total was 66 on July 15. Daily death totals are significantly smaller than the county’s peak and on a fairly steep decline but have not declined to the level they were at before the county’s surge. In the most recent day of complete data, Tuesday, Aug. 25, the seven-day daily average was 13 deaths a day, the smallest its been since June 15, just after the start of the county’s surge in deaths. In early June and prior, before the surge, county death totals were consistently below 10 a day.
