US cases of an intestinal infection from the cyclospora parasite that causes diarrhoea, nausea and other gastrointestinal symptoms have surged in recent days, with 34 states reporting infections, according to the U.S. Centres for Disease Control and Prevention (CDC).
Michigan, which reported its outbreak in May, recorded 3,309 cases on Tuesday.
Cyclosporiasis is an intestinal infection that can be contracted by consuming food, typically raw fruits and vegetables, or water contaminated with faeces, that transmit the cyclospora parasite, according to the CDC.
Symptoms can range from mild to severe, with children, older adults and people with weakened immune systems facing a higher risk of serious illness.
