Read, Watch or Listen

U.S. health authorities are investigating a rapidly expanding outbreak of cyclosporiasis, a parasitic infection that causes severe watery diarrhea, across at least 18 states. As of early July, Michigan reported nearly 700 cases, a sharp increase from 170 less than a week earlier and far above its usual annual average of about 50. The Centers for Disease Control and Prevention recorded more than 400 cases nationally by last Friday and described the clusters as concerning. The Food and Drug Administration is working with the CDC to identify the contaminated food source, which is suspected to involve raw produce or water but remains unknown.

Why This Matters to You

Cyclosporiasis is a nasty bug causing severe diarrhea. It's spreading fast across 18 states, including a big jump in Michigan. The source is suspected to be raw produce or water. Until officials find the culprit, consider washing produce thoroughly and drinking filtered water.

The Bottom Line

This outbreak is a serious health concern. With over 400 national cases and 20 hospitalizations, it's not business as usual. Officials are working hard to trace the source. Worth forwarding if you know someone who eats salads or drinks tap water.
