**Diarrhea-Inducing Parasite Spreading Across the US**
US health officials are currently facing a challenging outbreak of cyclosporiasis, a foodborne illness caused by the parasite cyclospora cayetanensis. As of now, at least 145 individuals across 17 states have tested positive for this parasite, which is known to cause severe diarrhea and dehydration. The Centers for Disease Control and Prevention (CDC) has indicated that the actual number of cases may be significantly higher due to underdiagnosis.
Since the outbreak began in early May, 20 people have been hospitalized, although there have been no reported fatalities linked to the illness. New York has been identified as a significant hotspot, with estimates of infections ranging from 31 to 80 cases. Other states affected by the outbreak include Alaska, Colorado, Connecticut, Florida, Georgia, Illinois, Louisiana, Massachusetts, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, and Wisconsin.
Symptoms of cyclosporiasis typically manifest about a week after exposure and can include explosive, watery diarrhea, bloating, gas, stomach cramps, nausea, and vomiting. Some patients may also experience fatigue and fever, while others may remain asymptomatic. If untreated, the infection can persist for over a month, often resulting in recurring episodes of diarrhea.
The CDC notes that cyclosporiasis is generally contracted through the consumption of food or water contaminated with feces. While the illness can be effectively treated with antibiotics, it is not routinely detected by standard laboratory tests, which contributes to the number of undiagnosed cases.
The cyclospora parasite is endemic to tropical and subtropical regions, including countries like Guatemala, Peru, and Nepal. Notably, there is no evidence suggesting that it can be transmitted from person to person. Given that many of the individuals diagnosed in this outbreak have not traveled outside the United States recently, health officials suspect that the source of the infection may be domestically distributed produce.
Public health authorities at local, state, and federal levels, including the CDC and the Food and Drug Administration (FDA), are actively investigating several clusters of cases across multiple states. Efforts are ongoing to identify potential sources of the outbreak.
Historically, previous outbreaks of cyclosporiasis in the United States have been linked to various foods, including cilantro, raspberries, sweet peas, lettuce, and basil imported from Mexico. In light of the current outbreak, the CDC has recommended that consumers wash leafy greens thoroughly with cold running water to reduce the risk of exposure to the parasite.
As investigations continue, health officials urge the public to remain vigilant about food safety practices and report any symptoms consistent with cyclosporiasis to healthcare providers. The situation remains fluid, and updates from health authorities are expected as they work to pinpoint the source of this widespread outbreak.
