TEMPE, AZ — As football fans packed the stadium Thursday night to watch the Sun Devils play their first game of the season, Mother Nature made a halftime appearance by bringing a haboob.

With all of that dust comes concerns of air quality — and Valley Fever.

The health condition is caused by spores in the dirt and dust, and can impact both humans and animals.

According to the CDC, most people who breathe in the spores don’t get sick. But there are some that do, and both pets and humans can develop breathing issues.

There can be more serious consequences if cases are left untreated.

Dr. Carroll says new residents to the Phoenix metro area are more likely to get Valley Fever in their first five years of living here, as they adapt to life in the desert.
