The Cyclospora parasite is in Massachusetts. Here's what to know

Key Points:

• The CDC is investigating multiple clusters of cyclospora cases across several states, with no confirmed link between all cases so far; the parasite spreads through contaminated food or water and is treatable with antibiotics.
• Cyclospora is a parasite, distinct from bacteria or viruses, causing symptoms like diarrhea, loss of appetite, fatigue, and stomach cramps, which can last up to a month or longer, especially in vulnerable populations.
• The recent increase in reported cases is partly due to improved testing methods that now detect cyclospora more effectively, although the FDA is investigating potential food sources such as onions, cucumbers, and cilantro.
• Similar outbreaks have occurred before, including one in the 1990s linked to contaminated raspberries, and while cyclospora is treatable, it often causes prolonged and debilitating symptoms.
• Health experts emphasize thorough hand-washing and washing all produce as key preventive measures, advising against discarding foods until the specific source of contamination is identified.
