PHOENIX — Arizona health officials reported 3,858 more positive coronavirus cases on Sunday, the most reported in a single day in the state so far.
The Arizona Department of Health Services also reported 9 additional deaths.
The numbers pushed Arizona’s documented COVID-19 totals to 73,908 cases and 1,588 known deaths.
The 3,858 cases topped Saturday’s tally of 3,591 and was the seventh time in the last 10 days that daily cases surpassed the 3,000 mark.
Pinal County reported 196 new cases Sunday bringing the total to 3,350. Two more deaths were reported in the county for a total of 63.
The San Tan Valley/Queen Creek area continued its trend over the week of having the highest number of daily cases in the county with 45 for a total of 710. Casa Grande's three ZIP codes continue to be the top hot spot in the county with 42 new cases for a total of 744.
Some Arizona hospitals have begun activating surge plans to increase their capacity to treat coronavirus patients as confirmed cases rise and more people seek treatment.
Large hospitals activating plans to add capacity to treat COVID-19 patients included Banner Desert Medical Center in Mesa and Valleywise Health Medical Center in Phoenix.
The number of infections is thought to be far higher because many people have not been tested, and studies suggest people can be infected with the virus without feeling sick.
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.
