(BINGHAMTON, NY) As you may have seen in news headlines or social media memes, there’s explosive diarrhea going around. Understanding how the immune system responds to the parasite that causes the unfortunate disease called cyclosporiasis can help explain why the infection is mild in some people but can cause severe or long-lasting illness in others.
The 2026 outbreak of cyclosporiasis in the U.S. has sickened over 4,100 people as of July. Public health officials have traced a major cluster of illness to contaminated produce imported from Mexico.
