This illustration, created at the U.S. Centers for Disease Control and Prevention, reveals ultrastructural morphology exhibited by coronaviruses. Note the spikes that adorn the outer surface of the virus, which impart the look of a corona surrounding the virion, when viewed electron microscopically. A novel coronavirus, named Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), was identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China in 2019. The illness caused by this virus has been named coronavirus disease 2019 (COVID-19).

PHOENIX (AP) — Arizona on Saturday reported 3,628 additional COVID-19 cases and 30 more deaths amid increasing hospitalizations as health officials urged residents to take precautions during Thanksgiving gatherings to prevent infections.

The Department of Health Services recommended holding Thanksgiving celebrations outside along with masks, social distancing and staying home if sick.

“Don’t let down your guard, even around close friends and relatives who aren’t members of your household,” the department said on Twitter.

Arizona has been experiencing a rise in cases, hospitalizations and deaths since late September and early October. Officials have cited business and school reopenings and public weariness with COVID-19 precautions.

With the additional cases and deaths reported Saturday, the state's totals rose to 295,334 cases and 6,457 deaths, according to the state's coronavirus dashboard.

Hospitalizations reached 1,916 as of Friday, with 435 of those patients in intensive care beds, for a total of 24,181 over the outbreak.

The number of reported 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. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia and death.

In other developments:
