South Carolina Reports Rise in Cyclosporiasis Cases

South Carolina health authorities have identified 30 confirmed cases of cyclosporiasis as officials monitor a recent uptick in the illness.

Current Health Status

State health officials confirmed that 30 individuals in South Carolina have tested positive for cyclosporiasis. This parasitic infection, caused by the protozoan parasite Cyclospora cayetanensis, has prompted increased surveillance among local medical providers and public health departments.

While the exact source of the current outbreak remains under investigation, health experts typically associate the spread of this parasite with contaminated fresh produce, such as berries, leafy greens, or herbs. Symptoms of the infection often include gastrointestinal distress, though the specific onset and severity can vary among patients.

Understanding Cyclosporiasis

Cyclosporiasis is primarily transmitted through the ingestion of contaminated food or water. The parasite is often resistant to standard chlorine treatments, making it a challenge for food processing and water treatment facilities to eliminate entirely.

Common symptoms reported by those infected include:

  • Severe watery diarrhea
  • Nausea and vomiting
  • Abdominal cramping
  • Loss of appetite and weight loss
  • Fatigue

Because symptoms can mimic other gastrointestinal illnesses, health officials emphasize the importance of clinical testing to confirm a diagnosis. Most healthy individuals recover without specific treatment, but those with weakened immune systems may require antiparasitic medication to manage the infection.

Public Health Response

The South Carolina Department of Health and Environmental Control (DHEC) and other local agencies are working to track the movement of affected individuals to identify potential common exposure points. Identifying a specific food item or geographic location is a priority to prevent further transmission.

Health officials advise the public to practice thorough hand hygiene and to wash fresh produce meticulously. If residents experience persistent gastrointestinal symptoms, they are encouraged to contact a healthcare professional immediately for evaluation and testing.
