Arizona reports 3,858 more COVID-19 cases, the highest single day tally so far

Arizona health officials reported 3,858 more confirmed coronavirus cases on Sunday, the most reported in a single day in the state so far. 

It was also the seventh time in the last 10 days that daily cases surpassed the 3,000 mark.

The Arizona Department of Health Services also reported nine additional deaths. That pushes Arizona's documented COVID-19 totals to nearly 74,000 cases and 1,588 known deaths.

Some Arizona hospitals have begun activating surge plans to increase their capacity to treat COVID-19 patients as confirmed cases rise and more people seek treatment. 

Arizona became a coronavirus hot spot following Gov. Doug Ducey's lifting of stay-home orders last month.

Vice President Mike Pence called off plans to hold rallies in Arizona and Florida amid the new case spikes.
