Arizona reports 637 new coronavirus cases, 105 more deaths

This is a regularly updated story with the latest information, news and updates about the coronavirus and its impact in Arizona and beyond for Wednesday, Aug. 19.

PHOENIX – Arizona health authorities reported 637 new coronavirus cases and 105 additional deaths on Wednesday morning.

That put the state’s documented totals at 195,557 COVID-19 infections and 4,634 fatalities, according to the Arizona Department of Health Services.

Multiple key metrics about the severity of Arizona’s pandemic, including coronavirus-related hospitalizations, are at or near the lowest they’ve been in a month or more.

The rolling seven-day average for newly reported cases declined Tuesday to 883.29, the lowest seen since June 5, according to tracking by The Associated Press.

The seven-day average of newly reported deaths dipped to 47.14, the lowest mark since July 10.

The seven-day average for new cases peaked July 6 at 3,844, and the stat for deaths reached a high of 94 on July 30.

The spread of coronavirus in Arizona has been slowing in the month-plus since the implementation of face mask requirements by local governments in many areas — including all of Maricopa County — and statewide executive orders to close businesses such as bars and gyms and to restrict restaurant occupancy.

Those moves were made after the state became a global hot spot for the coronavirus, which has no impact on some people and is seriously debilitating or fatal for others. Infected people without symptoms – which include but are not limited to cough, fever and difficulty breathing — are capable of spreading the virus.

Arizona’s weekly positive rate for COVID-19 diagnostic tests, which shows how much the virus is spreading, is on pace to decline for the seventh consecutive week.

For the 5,308 samples taken since Sunday that have been processed and recorded, the positive rate is 5%. If that rate holds up, it would be the lowest since the week starting May 10.

Weekly rates are based on when the samples are taken, not when they are reported, so the percentage for recent weeks can fluctuate as labs get caught up on testing and the results are documented by the state.

The Arizona health department’s daily reports present case, death and testing data after the state receives statistics and confirms them, which can lag by several days or more. They don’t represent the actual activity over the past 24 hours.

The hospital data posted each morning, however, is reported the previous evening by the hospitals and shows coronavirus-related hospitalizations at their lowest points since early June.

The number of Arizona’s confirmed or suspected COVID-19 inpatients fell to 1,160 on Tuesday, the fewest since June 3.

The number of COVID-19 patients in ICU beds dipped to 414, the second-fewest since June 9.

COVID-19 inpatients peaked at 3,517 on July 13, and COVID-19 patients in ICU beds topped out at 970 the same day.

Overall, inpatient beds were 81% full on Tuesday for the second consecutive day. The inpatient occupancy rate peaked at 88% on July 9-10.

The ICU occupancy rate was 80% for the fourth consecutive day. It topped out at 91% on July 7.

Hospital bed data on the health department website does not include surge beds that have not been activated but can potentially increase capacity.
