US experiences surge in cyclosporiasis cases
Since May 1, there have been 1,645 confirmed cases of cyclosporiasis in the United States, with over 5,100 additional cases currently under investigation, according to the US Centers for Disease Control and Prevention (CDC). This significant rise in incidents highlights ongoing public health concerns, reports BritPanorama.
The growing outbreak has been particularly noted in Michigan and Ohio, with links to further cases in West Virginia and Kentucky. Symptoms of cyclosporiasis can include watery diarrhea, cramping, and bloating, persisting for weeks.
Cases have now been detected in 34 states. Cyclospora activity typically peaks in spring and summer; however, the current number of confirmed cases is over six times higher than the total at the same time last year. Including all suspected cases, this year’s total is 27 times greater than last year’s figures for this period, as indicated by a recent health alert from the CDC.
Dr. Gwen Biggerstaff, deputy director of the CDC’s Division of Foodborne, Waterborne, and Environmental Diseases, emphasized the severity of the outbreak, stating, “This is much, much higher than what we’ve seen last year or the year before,” describing it as “a very big shift” from previous seasons. Approximately one in eleven reported cases has resulted in hospitalization. Currently, no fatalities have been documented, though the outbreak persists across at least 34 states.
An additional CDC investigation notice released on Tuesday reported that around 400 cases across Michigan, Ohio, West Virginia, and Kentucky “appear to be epidemiologically linked,” suggesting a potential common source for these infections.
In Michigan, over 3,300 cases of cyclospora have been reported during ongoing outbreak investigations. The state health department indicated that recent findings point towards lettuce or salad greens as likely sources, while keeping other possibilities open.
Historical context shows that the largest recorded cyclospora outbreak in the US involved approximately 1,500 cases connected to raspberries, as noted in a 2023 report from the US Department of Agriculture’s Food Safety Inspection Service.
As the CDC continues its investigations, authorities and health officials remain vigilant in tracking and managing the outbreak to mitigate further spread.
