How to prevent it, how long it lasts, can pets get it

Key Points:

• Michigan is experiencing a rapidly growing cyclosporiasis outbreak, with over 1,500 reported cases since June 22 and daily increases of 20% to 30%, though actual cases are likely higher due to underreporting and asymptomatic infections.
• Cyclosporiasis is caused by the cyclospora parasite, typically transmitted through contaminated food or water, and symptoms include watery diarrhea, abdominal cramps, nausea, and fatigue; severe cases may require hospitalization.
• Health officials have not yet identified the outbreak’s source, but past U.S. outbreaks have been linked to imported fresh produce such as bagged salads, herbs, and berries; cooking produce to at least 158°F is the most effective way to kill the parasite.
• Preventive measures include thoroughly washing fresh produce under running water, avoiding prewashed bagged salads, and practicing good hand hygiene, though washing alone may not completely eliminate the parasite.
• Treatment involves antibiotics, specifically trimethoprim sulfamethoxazole (Bactrim or Septra), and testing via stool samples is necessary for diagnosis, with results taking from one to five days depending on the test used.
