Federal health officials are currently investigating a second outbreak of cyclosporiasis, a parasitic intestinal illness, as the United States grapples with a record number of cases nationwide. This marks the second distinct outbreak of the illness to be identified this year.
The ongoing situation has already resulted in a record high for reported cyclosporiasis cases in the U.S., with over 11,000 individuals falling ill across 41 states. The specific source of this record-breaking number of infections has not yet been fully identified.
The first identified outbreak earlier this year was linked to iceberg lettuce imported from Mexico. Health authorities have stated that they are now working to trace the origin of the most recent wave of infections.
This second outbreak has been associated with at least 72 reported cases. Federal agencies are actively conducting investigations to determine the source and prevent further spread of the parasite. Further details regarding the specific foods or products implicated in the second outbreak have not yet been released.
Cyclosporiasis is an intestinal illness caused by the parasite Cyclospora cayetanensis. Symptoms typically include diarrhea, loss of appetite, weight loss, stomach cramps, bloating, gas, nausea, and fatigue. Some individuals may also experience vomiting. The parasite is transmitted to people through contaminated food or water.
