Even before the disaster in Flint the number of cases of legionnaires' disease had been rising in Michigan for the last few years.
That's why the state issued some guidelines to help protect your family this summer. Pool and hot tub owners should make sure they're using enough chlorine.
It can be tough to maintain the right level when the water is warm.
The risk of coming in contact with legionella from your home water system is low, but it's a good idea to clean your shower heads regularly just in case.
Scrape any sediment off and then soak it in a gallon of water with a tablespoon of bleach.
You should also clean water heaters and whole-home humidifiers by following the manufacturer's instructions.
Anyone with pneumonia symptoms like shortness of breath, muscle aches and a high fever should see a doctor right away.
