Michigan's cyclosporiasis outbreak is growing at an alarming rate, with over 1,500 cases reported since June 22. The illness, caused by the cyclospora cayetanensis parasite, is spreading rapidly, with a 20-30% increase in cases daily. The incubation period can range from two days to two weeks, and the source of the outbreak remains unknown. The parasite is so tiny that it can only be seen with a microscope and is typically contracted through contaminated food or water. While it is not endemic to Michigan, the state has seen an increase in cases due to imported produce from subtropical areas. The symptoms of cyclosporiasis include watery and sometimes explosive diarrhea, abdominal cramps, and nausea. The outbreak has led to hospitalizations and the Michigan Department of Health and Human Services has issued recommendations to reduce the risk of infection, such as cooking leafy greens and avoiding prewashed bagged lettuce. However, washing fruits and vegetables may not completely eliminate the parasite. The outbreak has also been linked to bagged salad mixes and kits, and the FDA warns that cyclospora is highly persistent in the environment. The best way to prevent infection is to cook food to a temperature of at least 158 degrees and thoroughly wash all produce. The article also discusses the treatment options for cyclosporiasis, including antibiotics, and the importance of testing to confirm the diagnosis. The author emphasizes the need for further investigation to identify the source of the outbreak and the potential impact of climate change on the spread of the parasite.
