Nearly 1,000 cyclospora cases reported in Michigan in largest-ever parasite outbreak

NEW YORK: A diarrhea-causing parasite outbreak has sickened nearly 1,000 people in Michigan, making it the largest cyclospora outbreak ever recorded in the state, and among the biggest reported in US in recent years.While no deaths have been reported, Michigan first alerted the public to the outbreak last week after more than 170 cases were detected in the southeastern part of the state since June 22.In neighboring Ohio, Lucas County has reported 306 cases, while northwest Ohio has recorded more than 500 infections, AP cites.Source of infection still unknownHealth officials are yet to identify the source of the infections. "There is clearly a linked outbreak happening right now," Michigan chief medical executive Dr Natasha Bagdasarian told The Associated Press.Experts say the actual number of infections is likely much higher because routine food poisoning tests often fail to detect the parasite.Investigators also face challenges because cyclospora cannot be grown in laboratories, making it difficult to confirm contaminated food sources.What is cyclospora?Cyclospora is a microscopic parasite that infects the intestines and causes cyclosporiasis. Outbreaks are most common during the warmer spring and summer months.The parasite spreads through food or water contaminated with human feces. Past outbreaks have been linked to contaminated fresh produce, including leafy greens, herbs and fruits exposed to polluted irrigation water.How can people stay safe?According to the US Centers for Disease Control and Prevention (CDC), the infection is usually treated with antibiotics and is rarely life-threatening. Anyone experiencing diarrhea lasting several days should seek medical advice and discuss the possibility of cyclospora infection with their healthcare provider.Health officials recommend washing fresh fruits and vegetables thoroughly before eating them, although washing may not completely remove the parasite.Catch the latest world news and top headlines.
