If you've been dealing with stomach issues that just won't go away, an infectious disease expert says it may be more than a routine stomach bug.
Dr. MarkAlain Déry says the United States is experiencing its largest known outbreak of Cyclospora, a foodborne parasite that can cause prolonged gastrointestinal illness. Louisiana is among more than 30 affected states, and Déry says he's already treated patients in the New Orleans area.
"We usually see only a few dozen cases a year," Déry said. "Now we're seeing thousands."
Health investigators have linked the outbreak to contaminated produce, including shredded cabbage, iceberg lettuce and, in some cases, berries. Because the parasite can hide in the crevices of certain fruits and vegetables, Déry recommends using extra caution until the outbreak subsides, particularly for older adults and people with weakened immune systems.
Unlike many viral stomach illnesses that resolve within a couple of days, Cyclospora infections can linger.
"This isn't something you just let run its course," Déry said. "Symptoms can come and go for weeks if it's not treated."
The parasite commonly causes severe diarrhea, bloating, abdominal discomfort and dehydration. Déry says the illness follows a cycle, with patients often feeling better for a day or two before symptoms return.
The good news is that Cyclospora is treatable with the prescription antibiotics, though patients with sulfa allergies should let their healthcare provider know because an alternative treatment may be needed.
Until health officials determine where the outbreak stands, Déry says he's personally avoiding bagged shredded cabbage and similar produce.
His advice: If you've developed persistent stomach symptoms after eating fresh produce, don't assume it's just a passing stomach virus. Contact your healthcare provider, especially if symptoms continue or worsen.
