The United States is experiencing a widespread outbreak of cyclosporiasis, a parasitic infection causing watery diarrhea, with cases reported in over thirty states. Since May 1st, approximately 7,000 infections have been reported to the CDC, though officials believe the actual number is significantly higher due to underreporting. Michigan has been particularly affected, with over 3,000 cases reported since May, leading authorities to suspect contaminated lettuce as a potential source. However, health organizations caution against drawing definitive conclusions, suggesting multiple sources are likely given the outbreak’s scale. The investigation is hampered by the delayed onset of symptoms – typically one to two weeks after exposure – and recent cuts to public health staffing. The CDC advises thorough handwashing and careful washing of raw fruits and vegetables to prevent infection.
