The largest Cyclospora outbreak in years has sickened over 18,000 people across 45 states since May, with more than 400 hospitalized, according to multiple reports. The source of the outbreak remains a mystery, but public health officials have traced a major cluster of illness to contaminated produce imported from Mexico.

The infection is caused by the parasite Cyclospora cayetanensis and spreads via the fecal-oral route when someone eats food or drinks water that has been contaminated with human feces. Experts are now investigating whether person-to-person transmission could occur through fomite transmission, where an infected individual fails to wash their hands after using the bathroom and touches a surface like a bus or subway handrail.

According to The Conversation, the severity of cyclosporiasis depends largely on how well the immune system controls it. In healthy people, helper T cells release interferon-gamma, which instructs infected tissues to stop parasites from multiplying. However, young children, older adults, and people with weakened immune systems are at higher risk of severe infection.

The Centers for Disease Control and Prevention (CDC) acknowledges that while direct person-to-person transmission is unlikely, it is not impossible. The agency states that it takes at least one to two weeks in the environment for Cyclospora to become infectious after passing in a bowel movement. Experts emphasize that this is not a time to panic but rather an outbreak that requires careful monitoring and public health measures.
