A surge in cases of explosive diarrhea caused by the parasite *Cyclospora cayetanensis* is currently affecting 34 states across the United States and may soon cross the border into Mexico, according to infectologist Alejandro Mac\u00edas. He revealed on Wednesday that he has already treated cases of this parasite within Mexican territory. <\/p>\n
Since May, the Centers for Disease Control and Prevention (CDC) have confirmed 1,645 cases\u2014four times higher than the same period in 2025\u2014with investigations ongoing to identify the contamination source. The outbreak notably escalated after June 22, with Michigan reporting nearly 1,000 cases in just a few weeks, a record for the state that usually sees around 50 annually. <\/p>\n
*Cyclospora* does not spread directly from person to person. Instead, it requires about a week to mature in the environment before becoming infectious. The parasite primarily contaminates irrigation water used for leafy greens such as lettuce, cilantro, and parsley\u2014vegetables that Mac\u00edas highlights as the highest risk in Mexico. <\/p>\n
The timing is concerning: Mexico\u2019s current rainy season brings temperature and humidity conditions that favor the parasite\u2019s spread. \u201cThe circumstances are set, especially with the temperature and humidity during the rainy season. It\u2019s perfectly possible that it will arrive,\u201d Mac\u00edas told Uno TV. <\/p>\n
While Mexico has seen isolated cases of cyclosporiasis, Mac\u00edas clarifies these are anecdotal and not yet linked to the US outbreak. His colleagues have independently confirmed similar cases, but official data from the General Directorate of Epidemiology is still pending. <\/p>\n
For migrants and residents in Mexico, especially those relying on fresh produce, this emerging health risk underscores the importance of vigilance and proper food hygiene. As the situation develops, public health authorities will need to strengthen surveillance and communication to prevent a wider spread.<\/p>\n","protected":false},"excerpt":{"rendered":"
