The Centers for Disease Control and Prevention reported a nationwide outbreak of cyclosporiasis with case numbers rising and no identified source.
The surge in infections poses a significant public health challenge because the contaminated food or water source remains unknown, leaving consumers at risk.
Health officials said there are now nearly 7,000 confirmed or suspected cases of cyclosporiasis nationwide [1]. This total includes 1,645 lab-confirmed cases reported as of Tuesday, July 14 [5]. This figure represents an increase of more than 800 cases from the previous update [6].
The outbreak has reached at least 34 states [2]. According to the CDC, more than 140 people have been hospitalized [3]. No deaths have been reported [4].
Cyclosporiasis is caused by the Cyclospora parasite. Because the source is not yet identified, the CDC issued an alert to physicians to increase testing to help track the spread. Officials said case numbers are expected to continue to rise through the end of August [7].
"There are now nearly 7,000 confirmed or suspected cases of cyclosporiasis nationwide," the CDC said [1].
Medical providers are being urged to maintain high suspicion for the parasite in patients presenting with gastrointestinal symptoms. The agency continues to investigate the origin of the contamination to prevent further infections.
“There are now nearly 7,000 confirmed or suspected cases of cyclosporiasis nationwide.”
The disparity between lab-confirmed cases and suspected cases suggests a significant under-reporting or testing gap, which is common in parasite-driven outbreaks. Until the CDC identifies the specific contaminated produce or water source, the public remains vulnerable to a seasonal surge that typically peaks in late summer.
