CDC Investigates Rise in Cyclosporiasis Cases Across the U.S.

The Centers for Disease Control and Prevention (CDC) is investigating a surge in cyclosporiasis cases. This intestinal illness causes diarrhea, nausea, and fatigue. As of now, federal health authorities report these cases in 34 states.

Current Situation

As of Tuesday, the CDC has received reports of 1,645 confirmed cases. Cyclosporiasis is caused by the Cyclospora parasite. The true infection numbers are likely higher, as many people recover without medical treatment.

Michigan reports the highest cases at 3,309. Nationwide, 141 hospitalizations have occurred with no deaths. The CDC is probing multiple clusters, with a multistate outbreak affecting Michigan, Ohio, West Virginia, and Kentucky.

The illness spreads via contaminated food or water. Past outbreaks linked to fresh produce, including tainted lettuce and salads, have caused widespread infections.

Regional Impact

Cases have spread from California to Florida since May. The Midwest and Northeast, notably Michigan and New York, face significant impacts. Ohio reported 177 cases as of July 2, mostly in June.

Dr. Bruce Vanderhoff from Ohio advises treating cyclosporiasis seriously due to risks like dehydration that necessitate emergency medical care. Affected individuals range in age from 5 to 88.

Source of Outbreak

The specific source remains unidentified. The CDC continues interviews with affected individuals to determine potential exposure sources. Foods linked to previous outbreaks include raspberries, basil, cilantro, snow peas, and lettuce.

Doctors are urged to test for cyclosporiasis. Stool samples need specific lab tests for accurate diagnosis.

Prevention Measures

Cooking produce at 158 degrees Fahrenheit or higher effectively prevents infection. Public health officials recommend thorough rinsing of fresh produce before eating or cooking.

Standards for food safety should be maintained. Wash hands before and after handling produce. Health officials stress the importance of cleaning fresh produce, as food sources for recent cases are unknown.

If Symptoms Appear

If symptoms arise, like prolonged watery diarrhea along with fatigue, seek medical care. Dr. Kawsar Talaat advises consulting a doctor if symptoms persist or return. Accurate diagnosis requires targeted stool testing.

The effective treatment includes the antibiotic trimethoprim/sulfamethoxazole (Bactrim or Septra) over 7 to 10 days. The infection often resolves on its own in healthy adults, but vulnerable populations should be tested and treated promptly.
