(NewsNation) — A mysterious parasitic ailment has been steadily spreading across more than a dozen U.S. states, leaving health officials perplexed as they race to identify its origin. The illness is causing symptoms so severe that some patients experience what is described as “explosive” diarrhea.
The Centers for Disease Control and Prevention (CDC) was first alerted to significant outbreaks of cyclosporiasis back in early May. According to the CDC’s most recent update, which was published on July 1, there were 145 reported cases extending over 17 states.
However, as of this past Monday, the impact of the illness has widened, now affecting at least 18 states. Illinois, Michigan, New York, and Texas are bearing the brunt, reporting the highest numbers of cases thus far.
The situation is particularly concerning in Michigan, where health authorities have confirmed 572 instances of cyclosporiasis as of July 4. In New York, the count has surpassed 100 cases. Unfortunately, specific figures for Illinois and Texas remain undisclosed. It’s likely these numbers don’t capture the full extent of the outbreak, as many individuals may not seek medical care unless their symptoms are particularly severe.
Other states linked to the outbreak include Alaska, Colorado, Connecticut, Florida, Georgia, Louisiana, Massachusetts, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia and Wisconsin.
So far, no specific produce, product, or supplier has been identified by the CDC or the U.S. Food and Drug Administration as the source of the outbreak.
What is cyclosporiasis?
Cyclosporiasis is a type of food poisoning caused by a parasite, according to the CDC. People usually become infected from consuming food or water contaminated with feces. Symptoms usually occur within two to 14 days after ingestion.
While cyclosporiasis is not usually life-threatening, people can experience severe symptoms, including cramps, nausea, fatigue and vomiting. The most commonly reported symptom is “watery diarrhea with frequent, sometimes explosive, bowel movements,” according to the agency. Other common symptoms include loss of appetite, weight loss, increased gas, body aches, headache, low-grade fever and other flu-like symptoms.
If it’s not treated with antibiotics, it can last anywhere from a few days to over a month. Symptoms can also go away and return multiple times.
The health agency noted there’s a higher risk of infection when living in or traveling to tropical or subtropical regions, where the parasite is more common.
Previous causes of cyclosporiasis outbreaks
Outbreaks of cyclosporiasis are typically traced back to prepackaged food and fresh produce. Previous outbreaks have been linked to:
- Bagged salad mixes and kits
The last outbreak in 2019 was linked to basil that was imported from Mexico. At least 2,400 people were sickened in 37 states and the District of Columbia, according to data from the National Library of Medicine.
Protecting yourself from cyclosporiasis
If you plan to prepare or eat raw foods, the CDC recommends taking the following steps to reduce the risk of exposure:
- Wash your hands with soap and water before and after handling or preparing raw fruits and vegetables.
