Highlights
- A major dust storm blanketed the Phoenix Valley on Tuesday, with multiple outlets calling it one of the strongest on record.
- Dr. Frank LoVecchio, an ER physician and ASU professor, says people with lung disease, heart disease, the very young, the very old, and the immunosuppressed are most at risk.
- The American Lung Association warns dust can carry mold spores, pollutants, and fungal spores linked to Valley Fever.
- Doctors recommend sensitive groups stay indoors; those who must go out should wear an N-95 mask.
A thick dust haze blanketed the Phoenix Valley on Tuesday after what Arizona's Family, KTAR, and FOX 10 Phoenix are calling one of the strongest dust storms on record to move through the area, triggering a high pollution advisory and prompting doctors to warn vulnerable residents to stay inside.
Emergency room physician and ASU professor Dr. Frank LoVecchio said the dust is not a significant concern for most healthy people but cautioned that others need to take it seriously. "For the average person, it's not going to be a big deal, but it is a big deal for many people," LoVecchio said. He identified people with lung disease, heart disease, the very young, the very old, and those who are immunosuppressed as most at risk, noting the dust can trigger asthma, strain the heart, and drive emergency room visits.
JoAnna Strother with the American Lung Association said the hazard extends beyond what is visible. "Dust particles often carry trapped allergens such as mold spores and pollutants that can trigger allergic reactions," Strother said, adding that the dust can also carry fungal spores capable of causing Valley Fever.
For those in sensitive groups, LoVecchio recommends staying indoors as much as possible; anyone who must go outside should wear an N-95 mask. The pollution advisory remains in effect as haze lingers over the Valley.
