Hawaii's Department of Health has confirmed a fourth case of cyclosporiasis, a parasitic intestinal illness caused by the Cyclospora cayetanensis parasite. The confirmation was reported by Kauai Now, which covers news across the Hawaiian islands.
Cyclosporiasis is not a common illness, and four confirmed cases draws attention from public health officials who track clusters of infection. The illness is typically contracted by consuming food or water contaminated with the parasite. Fresh produce, particularly imported fruits and vegetables, has been linked to outbreaks in the past. The parasite is not spread directly from person to person.
Symptoms of cyclosporiasis include watery diarrhea, loss of appetite, weight loss, cramping, bloating, nausea, and fatigue. The illness can last for weeks and in some cases longer if not treated. It is typically treated with a specific antibiotic combination. People with weakened immune systems may experience more severe illness.
The Hawaii Department of Health did not immediately specify whether the four cases were connected to a common source or whether investigators had identified a specific food item. Traceback investigations in cyclosporiasis cases can be complex and time-consuming, as the parasite has a longer incubation period than many other foodborne pathogens, making it harder for patients to recall exactly what they ate and when.
Health officials generally advise people to wash fresh fruits and vegetables thoroughly, though standard washing does not fully eliminate Cyclospora. Cooking produce to appropriate temperatures does kill the parasite. For people who develop symptoms consistent with cyclosporiasis, particularly prolonged or severe gastrointestinal illness, health officials recommend seeking medical attention and informing a doctor of any recent travel or food exposures.
The Department of Health has not yet announced whether any additional cases are under investigation.
