The National Syndromic Surveillance Program (NSSP) indicates an increase in ED visits for heat-related illnesses (HRI) (total of 30) since 5/10/22 throughout Michigan, primarily in southwest and southeast Michigan. Most HRI visits were male (73%), 18-44 years of age (57%), and a majority occurred in southwestern Michigan counties including Allegan, Berrien, Kalamazoo, Van Buren.
These are the first higher heat days this spring and people’s bodies might not yet have acclimated to warmer temperatures. Additionally, having limited or no access to air conditioning during high-temperature days with low- to mid- humidity can lead to increases in HRI. While national messaging for HRI awareness is usually targeted for children and senior adults, younger adults aged 18-34 have had higher ED rates for HRI in Michigan, as is the case this week.
Temperatures in the mid to high 80s are forecasted through Saturday for much of Michigan’s lower peninsula. Temperatures should lower to the mid-70s by Sunday.
