Arizona added one of the highest day-to-day case counts of COVID-19 since the pandemic began, pushing the state’s total cases over 18,400.

As of Friday morning, the Arizona Department of Health Services reports 18,465 cases and 885 deaths in the state, up 702 and 28 from Wednesday, respectively.

The Maricopa County Department of Public Health reports 8,998 cases and 401 deaths in Arizona’s most populous county.

For most people, the new coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. But for some — especially older adults and people with existing health problems — it can cause more severe illness, including pneumonia, and death.

Arizona does not report recoveries yet but is displaying the number of cases discharged from the hospital. That amount is at 4,551 — or 24.6% of total cases — as of Friday.

The Navajo Department of Health reported 102 new cases of coronavirus on the Navajo Nation and one more known death.

That pushes the numbers to 4,944 positive COVID-19 cases and 159 known deaths as of Wednesday night.

Tribal officials also said preliminary reports from eight health care facilities indicate about 1,620 people have recovered from COVID-19 with more reports still pending.

“We have to keep doing what we’re doing by wearing protective masks, complying with the weekend lockdowns, staying home and practicing social distancing,” Navajo Nation President Jonathan Nez said in a statement. “We are seeing some very good indications that the numbers are flattening.”

The tribe will have another weekend lockdown tonight until early Monday.

It will be the eighth weekend lockdown that also requires the closure of all businesses on the Navajo Nation that stretches into northeastern Arizona, northwestern New Mexico and southeastern Utah.
