This is a regularly updated story with the latest information about the coronavirus and its impact in Arizona and beyond for Nov. 21, 2020.

PHOENIX – Arizona health authorities on Saturday reported 3,638 new coronavirus cases with 30 additional deaths.

That put the state’s documented totals at 295,334 COVID-19 infections and 6,457 fatalities, according to the Arizona Department of Health Services.

Key pandemic metrics have been rising in Arizona at a rate not seen since the first wave hit in June and July. Cases have been surging since the beginning of October.

The number of Arizona’s confirmed or suspected COVID-19 hospital inpatients increased overnight to 1,916 on Friday, doubling the Nov. 1 figure of 918 and the most since Aug. 5.

The number of COVID-19 inpatients peaked July 13 at 3,517 and fell afterward as low as 468 on Sept. 27.

The number of COVID-19 patients in ICU beds decreased by two overnight to 435 on Friday, 87% above the Nov. 1 mark of 231 and the second most since Aug. 14.

The number of COVID-19 patients in ICU beds peaked July 13 at 970 and fell afterward as low as 114 on Sept. 22.

Arizona’s weekly percent positivity for COVID-19 diagnostic testing, an indicator of how much the virus is spreading in the community, has reached its highest level in four months.

The positivity rate was 9.8% for the 69,290 tests so far this week, the highest since it was 12% for the week starting July 19.

The weekly rate, which was 11% last week, peaked at 20% at the end of June and was down to 4% as recently as early October.

Official positivity 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 rolling seven-day average for the state health department’s newly reported cases was 3,159.86 for Friday after doubling in just two weeks, according to tracking by The Associated Press. It was the highest figure since July 20.

The seven-day case average peaked July 6 at 3,844 and fell afterward as low as 373.14 on Sept. 12.

The seven-day average of newly reported deaths has been bucking the recent trends and was at 24.29 on Friday, increasing day-to-day for just the fourth time in 11 days.

The seven-day death average peaked July 30 at 94 and fell afterward as low as 5.57 on Oct. 14.

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 hospitalization data posted each morning is reported the previous evening by the hospitals.

COVID-19, the disease caused by the novel coronavirus, 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.

Information about testing locations can be found on the Arizona Department of Health Services website.

Below are Saturday’s latest developments about the coronavirus pandemic from around the state, country and world:

  • The Navajo Nation reported 168 new coronavirus cases and three additional deaths, bringing the documented totals to 14,612 infections and 626 fatalities.
  • The Rock ‘n’ Roll Arizona Marathon announced the 2021 marathon and half-marathon would not take place due to the coronavirus pandemic.
