Diarrhoea parasite spreads across US as more than 10,000 cases recorded

A highly contagious parasite responsible for causing diarrhea has been spreading across more than a dozen US states, resulting in over 10,000 confirmed cases. The Cyclospora parasite, transmitted through contaminated food or water, can cause symptoms such as nausea, vomiting, and sometimes lasts over a month without treatment. The US Centers for Disease Control and Prevention (CDC) has officially linked the outbreak to nine states, with predictions suggesting it will soon affect at least 15 states.

Michigan has reported two deaths, both linked to underlying health conditions exacerbated by dehydration and infection. The Food and Drug Administration (FDA) has traced the outbreak to iceberg lettuce from central Mexico, supplied by Taylor Farms de Mexico, which was served at Taco Bell locations in multiple states. The lettuce has since been recalled.

Analysts in Mexico suspect a recent weather event may have contaminated farmed areas, leading to the outbreak. The CDC and FDA are investigating the outbreak, expecting the number of confirmed cases to rise despite the product recall. Former FDA commissioner Scott Gottlieb suggested weather conditions may have raised the risk of contamination.

The true number of cases is likely much higher than reported, with some analysts believing it could be 10 to 20 times the current count. The CDC has received reports of 10,468 confirmed cases, with an additional 12,255 unconfirmed cases. Michigan has recorded 11,508 total cases, significantly higher than the CDC's total confirmed caseload.

Health officials are conducting extensive patient interviews to trace the source of contamination, emphasizing the need for improved food safety and surveillance systems.
