A Scottsdale fire crew and an ambulance crew have been put under isolation protocol after transporting the second confirmed case of the new coronavirus in Arizona within the last week, according to the city of Scottsdale.

The second case was confirmed by the Arizona Department of Health Services on Tuesday morning to be a Maricopa County man in his 20s.

Scottsdale Fire Department paramedics assisted Maricopa Ambulance in transporting the man to a hospital, according to Kelly Corsette, a spokesperson for Scottsdale.

After the man tested positive for the new coronavirus, the four-person fire crew and two-person ambulance crew were "excluded from work" and following the social distancing guidelines for 12 to 14 days as directed by Maricopa County Department of Public Health, Corsette said.

One Scottsdale fire employee has since been cleared for work and none of crew members involved have shown any symptoms of illness.

The emergency crews are trained and equipped to respond to infectious diseases and their procedures would have reduced the risk of exposure, Corsette said.

The Maricopa County Department of Public Health is responsible for interviewing the patient, evaluating their circumstances, determining who else may be at risk and then contacting and helping those people.

"If you have not been contacted, public health has determined that you are not at risk of contracting COVID-19 from this individual," Corsette said.

On Wednesday, officials at HonorHealth, which operates five hospitals in Phoenix and Scottsdale, said that they are working with county health officials "following the presumptive positive test for coronavirus."

Officials said the man who tested positive for the new coronavirus was a "presumptive positive" case, meaning a test for coronavirus sent to a public health laboratory came back positive, and that the CDC will conduct further testing to confirm the diagnosis.

"HonorHealth, like all other health systems, has strict infection prevention protocols in place to handle suspected or confirmed cases of the illness," said a statement that HonorHealth spokesman Seth Kaplan released Wednesday evening.

"Because our staff and physicians follow standard practices and procedures to limit exposure to contagions, there is little cause for concern among anyone else who has been, or is currently being cared for, in the hospital."
