The recent surge in cyclospora infections has spread across multiple states, including Michigan, where over 1,200 cases have been reported, and Ohio, where northwest counties have seen more than 500 cases.
The Centers for Disease Control and Prevention (CDC) has identified an uptick in infections in dozens of states since mid-June, with illnesses reported in Texas and numerous other states as health officials investigate the source of the outbreak.
The hallmark symptom of a cyclospora infection is watery, often "explosive" diarrhea that can last for weeks or even months if left untreated, according to the CDC.
Other symptoms of cyclosporiasis include severe abdominal cramping, bloating, nausea, fatigue, and significant weight loss, making prompt medical attention essential for effective treatment.
The official outbreak season for the parasite runs from May 1 through August 31, a period during which warmer temperatures historically coincide with a spike in infections, according to the CDC.
While the exact cause of the current outbreak remains unknown, past infections have been linked to consuming contaminated fruits or vegetables, or being exposed to contaminated irrigation water.
To minimize the risk of infection, health experts recommend washing fresh produce thoroughly before eating, but note that this may not eliminate the risk altogether.
Michigan officials advise purchasing salad mixes or whole heads of lettuce instead of pre-washed, bagged lettuce, and recommend removing two to three leaves from the outer layer of the lettuce head before washing and cooking vegetables when possible.
