Street medicine teams search for homeless people to deliver lifesaving IV hydration in extreme heat

As temperatures reach triple digits in metro Phoenix, heat illness is especially deadly for people who live outside under the broiling desert sun. Homeless people accounted for nearly half of the 645 people who died last year from heat-related causes in Arizona's Maricopa County. A Phoenix health care nonprofit has begun a new program this year providing intravenous saline drips to dehydrated homeless people. Circle the City's street medicine team goes where they are — by a major freeway overpass, alongside dry riverbeds, at a city park and near the city's canals.
