Health officials are investigating a sharp increase in cyclosporiasis cases across the United States after reports confirmed that the foodborne illness has spread to 31 states, resulting in dozens of hospitalizations. The Centers for Disease Control and Prevention (CDC) says multiple investigations are underway to determine whether the reported cases are linked to a common source.
Cases Reported in 31 States
According to the CDC, 843 confirmed domestically acquired cases of cyclosporiasis had been reported as of July 9, with 86 hospitalizations and no deaths. Officials also noted that additional cases are still being reviewed, meaning the total number may continue to rise. The outbreak has affected residents in 31 states, making it one of the largest seasonal increases in recent years.
Several states, including Michigan, have reported significantly higher case numbers than normal. Health departments are working closely with federal agencies to identify any common food sources that may be responsible for the increase.
What Is Cyclosporiasis?
Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. People typically become infected by consuming food or water contaminated with the parasite. Fresh produce, including leafy greens, herbs, and berries, has been linked to previous outbreaks, although investigators have not identified a single source in the current cases.
Symptoms usually appear about one week after exposure and commonly include watery diarrhea, stomach cramps, nausea, bloating, fatigue, loss of appetite, and weight loss. Without treatment, symptoms can last for several weeks or even longer.
Investigation Continues
The CDC, state health departments, and the Food and Drug Administration are investigating several clusters of illnesses occurring across multiple states. Officials say there is currently no evidence that all reported cases are connected to a single nationwide outbreak, and investigations remain ongoing.
How to Reduce Your Risk
Health experts recommend washing fresh fruits and vegetables thoroughly, practicing good hand hygiene, and seeking medical care if symptoms develop after consuming potentially contaminated food. People experiencing prolonged diarrhea or signs of dehydration should contact a healthcare provider, as prescription antibiotics may be needed to treat the infection.
Public health officials continue monitoring the situation while working to identify the source of the rising number of cyclosporiasis infections across the country.
