The employee was isolated at home, and health officials are providing guidance to anyone who may have been exposed. 

Those counties are all covered by the governor's executive order requiring bars, gyms and other large gathering places to shut down, and restaurants to scale back service.

Just three Arizona counties -- La Paz in far western Arizona, and Greenlee and Gila in eastern Arizona -- have reported no cases of coronavirus. Officials in Arizona's rural counties have said they are suffering from a dire shortage of test kits.

Ducey also activated the National Guard to help grocery stores and food banks.

Here is a link to some coronavirus myth-busters, according to WHO. 


COVID-19 is believed to be primarily spread through coughs or sneezes. 

It may be possible for the virus to spread by touching a surface or object with the virus and then a person touching their mouth, nose or eyes, but this is not thought to be the main method of spread, the CDC says. 

You should consult your doctor if you traveled to an area currently affected by COVID-19 and feel sick with fever, cough or difficulty breathing. 

There is no vaccine for the coronavirus, so the best way to prevent COVID-19 and other respiratory diseases is to:

  • Avoid close contact with people who are sick.
  • Avoid touching your eyes, nose, and mouth.
  • Stay home when you are sick.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean and disinfect frequently-touched objects and surfaces using a regular household cleaning spray or wipe.
  • Wash your hands often with soap and water for at least 20 seconds. If soap and water are not readily available, use an alcohol-based hand sanitizer.
