A multistate outbreak of cyclosporiasis has been reported, with cases in 15 states. The outbreak is linked to lettuce sold at restaurants and some food stores. The Centers for Disease Control and Prevention has conducted laboratory tests, which suggest that the illnesses in several states were caused by the same strain of the cyclospora parasite.

This parasite can cause weeks of explosive diarrhea if left untreated. Further details about the outbreak are available from health officials and the source. The outbreak has affected multiple states, with six states recently added to the list of those affected.
