New numbers from the Arizona Department of Health Services show new COVID-19 cases in two counties.

Navajo County is reporting its first case, and two more cases have been confirmed in Maricopa County. A previous presumptive positive case reported on March 11 was later ruled negative. That balances out to 20 cases at the moment as of Tuesday, March 17.

Eight of the positive tests have been at private laboratories, which are not required to report the number of total tests and pending results, officials have said.

Maricopa County has nine cases, the most in Arizona.

The county Department of Health said the new cases are a man in his 50s who is recovering at home and a woman in her 60s who is hospitalized. A previously reported man in his 90s was later determined to be negative and is no longer considered a COVID-19 case.

Signs and symptoms of COVID-19, similar to the common cold or the flu, include a runny nose, cough, sore throat, fever, and the general feeling of being unwell.

Those who are sick are encouraged to stay home. Anyone who has tested positive should stay home, as well as their entire household and contact your medical provider.

Federal and state officials have differed on large gatherings, with the former saying avoid groups over 10 while the latter is saying avoid groups over 50.

People are advised against visiting nursing homes, retirement or long-term care facilities unless to provide critical help.
