Respiratory virus season is on its way, and health officials say it’s time to schedule seasonal vaccines for flu and COVID-19.

Climate change is prolonging the heat season in Phoenix and around the globe, according to new research from the NASA Goddard Institute for Space Studies.

Arizona State University’s hockey team may not have been following university policies when a student athlete collapsed during an outdoor practice in August, an initial report on the incident shows.

This summer was the hottest on record across the contiguous U.S. and a new report says that's attributable to carbon pollution. The impacts of climate change were especially evident in Arizona.

More than 400,000 people enrolled in the state Medicaid program could be subject to new work requirements starting in January. AHCCCS is launching a website to help Arizonans navigate the changes.

It has been a dry and dusty summer and those conditions raise the chances that people might inhale the tiny fungal spores that spread Valley fever.

In the future, Phoenix will not only see more intense high temperatures, but longer heat seasons, climate projections show.
