The United States has reported the first two deaths from the intestinal disease cyclosporiasis. Both fatalities occurred in Michigan, which has recorded over 11,000 cases of the infection. Overall, more than 18,500 cases have been diagnosed or laboratory-confirmed across the United States. U.S. authorities link this diarrheal illness, caused by the parasite Cyklospora cayetanensis, to iceberg lettuce served at the Taco Bell fast-food chain. In Michigan, 193 people were hospitalized, although the disease usually has a milder course. Symptoms, such as watery diarrhea, cramps, and bloating, appear up to two weeks after contact with the pathogen and can last for several weeks. Severe dehydration can lead to hospitalization, and the infection is treated with antibiotics administered for 7 to 10 days. Experts are also searching for other sources of infection due to its widespread nature.
