PHOENIX — A Pinal County woman announced Friday as a new presumptive positive coronavirus patient was believed to be the first case that was "community spread," and now two others in her household have also been diagnosed.

County health officials confirmed a second presumptive positive case in the state Friday, identifying the patient as a female healthcare worker in her 40s from Pinal County. Heads of the heath departments for Maricopa and Pinal counties did not identify where the woman works. She is currently hospitalized in stable condition in Maricopa County.

Pinal County health officials said the woman is not a known contact of any confirmed coronavirus patients and has not traveled to any areas where coronavirus is spreading widely. This has prompted county agencies to treat the case as the first instance of "community spread" in our state.

“Community spread refers to the spread of an illness for which the source of infection is unknown. Just like during flu season, if you get symptoms, you need to stay home and take care of yourself,” said Dr. Shauna McIsaac, director of Pinal County Public Health Department.
