Health officials in the United States are investigating a growing outbreak of cyclosporiasis, a parasitic infection that has been linked to thousands of confirmed and suspected cases across 34 states.
The illness is caused by Cyclospora cayetanensis, a microscopic parasite commonly spread through contaminated food or water. Symptoms can include severe watery diarrhoea, stomach cramps, nausea, loss of appetite, fatigue and, in some cases, weight loss.
According to health authorities, tracing the source of the outbreak has proven difficult because symptoms often appear one to two weeks after exposure, making it hard for patients to remember what they may have eaten. Laboratory testing to detect the parasite in food products can also be time-consuming.
Investigators suspect that more than one contaminated food source may be involved. Michigan and New York are among the states reporting the highest numbers of cases.
The U.S. Centers for Disease Control and Prevention (CDC), working alongside state health agencies, is continuing efforts to identify the source of the infections and prevent additional cases. In the meantime, residents have been advised to practice good hygiene, wash fruits and vegetables thoroughly, and seek medical attention if symptoms persist.
