Aug 25 (Reuters) – The Centers for Disease Control and Prevention on Tuesday reported 17,180 confirmed cases of cyclosporiasis in ​the United States, an increase of ‌1,464 cases from a week ago.

Here are some details:

• The CDC said it has received reports of 17,180 confirmed cases across 48 states plus ‌the ​District of Columbia, with ⁠922 hospitalizations and ⁠two deaths as of August 24. At least 11,844 additional cases may require further investigation and analysis, CDC said.

• The data ​include the cases reported in the ongoing multistate outbreak linked to recalled ⁠iceberg lettuce, CDC said, ⁠adding that it is investigating multiple ​clusters of cyclosporiasis.

• CDC and FDA are ​investigating at least six other clusters for ‌which sources have not yet been confirmed, CDC said.

• Michigan, the hardest-hit state, logged a slow 3% rise to 14,277 last ⁠week, hinting the outbreak may be easing.

• The cyclosporiasis outbreak is one of the largest foodborne ⁠illness events ‌in recent U.S. history. The ⁠illness is caused by the ​cyclospora ‌parasite, which can lead to ​diarrhea, nausea ⁠and other gastrointestinal symptoms.

• The outbreak has shaken U.S. consumers nationwide, causing many to forgo eating fresh produce or dining in restaurants.
