Pima County had 4,682 of the state's 43,443 confirmed cases.
That's more than double the 20,123 confirmed cases the state had on June 1.
A total of 1,271 people have died after contracting the virus, including 235 in Pima County.
Maricopa County has more than half the state's cases, with the number of confirmed COVID-19 cases hitting 23,880.
Because symptoms can take as long as two weeks to appear after exposure to the virus (while some people can remain entirely asymptomatic), health officials continue to urge the public to avoid unnecessary trips and gatherings of more than 10 people, especially if you have underlying health conditions, and have advised people to cover their faces with masks in public.
Although Gov. Doug Ducey told Arizonans that the state was "clearly on the other side of this pandemic" when he lifted his stay-at-home order on in mid-May, Arizona hospitals continue to see a steady rise in the number of people hospitalized with COVID symptoms, as well as more people visiting emergency rooms. This morning's Arizona Department of Health Services report shows that as of yesterday, a record 1,667 Arizonans were hospitalized, a jump of 658 people from the 1,009 hospitalized on June 1. A record number of 1,109 arrived at emergency rooms with COVID-like symptoms on June 17. Previous to June, the number of people seeking help in emergency rooms never topped 667, but the daily number hasn't dipped below 800 since June 5. The number of patients in ICU beds hit another record of 540 yesterday.
"There is an indication that we are not out of the woods yet," Ducey said.
Ducey, who wore a mask before beginning the press conference for the first time, said he would allow cities and counties to set their own policies in regard to mandating the wearing of masks. While he had previously blocked local jurisdictions from setting standards more strict than the state's emergency regulations, Ducey said different areas of the state were facing different circumstances, so he was relaxing his emergency regulations that limited the actions of local communities. He said it would be up to local communities to set up rules and penalties.
Tucson Mayor Regina Romero said she had asked City Attorney Michael Rankin to prepare a legal proclamation to require masks as soon as today.
Tucson City Councilman Steve Kozachik, who last week called on Ducey to allow local communities to set their own standards, called Ducey's announcement a "half-step."
"The fact that we can do masks is fine," Kozachik said. "We ought to be able to do more."
Kozachik yesterday called for the city to return to the emergency proclamation issued by Romero in March that limited restaurants to curbside service and closed bars, gyms, theaters and other gathering places. Kozachik said he believed the city's charter gave the council that authority, although he said he expected it would be challenged by Republican state lawmakers.
Meanwhile, the Pima County Board of Supervisors will meet Friday to vote on whether to mandate masks when people go out in public to slow the rising spread of COVID-19.
After Gov. Doug Ducey announced this afternoon that he would give local jurisdictions the power to mandate masks, Board Chairman Ramon Valadez called for the 3 p.m. meeting.
The ordinance, which is still being drafted, would apply countywide, including within all jurisdictions, Valadez said.
Pima County Supervisor Sharon Bronson said she was in favor of mandating masks.
Ducey, who had not emphasized the wearing of face masks before last week, recommended that people should “act responsibly” and wear the masks when out in public.
“Every Arizonan should wear a face mask,” Ducey said. “It’s the smart thing to do.”
Ducey also said his administration would be providing more guidance to businesses to prevent large gatherings.
In other pandemic news, Pinal County Sheriff Mark Lamb, who had earlier said he wouldn't enforce the state's emergency COVID-19 regulations, announced yesterday that he tested positive for COVID-19.
Lamb said on Facebook that he likely caught the virus at a campaign event and would be self-quarantining for 14 days even though he was asymptomatic.
He learned he was positive after taking a test ahead of a visit with President Donald Trump.
