A rare foodborne parasitic infection has become a growing public health concern in the United States after health officials confirmed two deaths linked to cyclosporiasis in Michigan. The fatalities come as the country reports more than 18,000 suspected cases of the disease during the current outbreak.
According to health authorities, this marks the first time deaths have been reported in connection with the ongoing outbreak in Michigan.
Two Deaths Confirmed in Michigan
The Michigan Department of Health and Human Services (MDHHS) confirmed that two people died after developing complications associated with cyclosporiasis.
Officials said both individuals had pre-existing medical conditions, and the infection, along with dehydration, worsened their health, ultimately contributing to their deaths. The department has not released any additional details about the patients.
Michigan Reports Thousands of Cases
Although cyclosporiasis is generally considered an uncommon illness and is rarely fatal, Michigan has witnessed a significant increase in cases this year.
According to MDHHS:
-
11,234 cases have been reported in Michigan.
-
193 patients have required hospitalization.
Health officials say the current outbreak is much larger than what is typically seen during the seasonal peak.
More Than 18,000 Cases Reported Across the US
The U.S. Centers for Disease Control and Prevention (CDC) has also acknowledged the outbreak and confirmed the two deaths.
Nationwide, more than 18,000 suspected cases have been reported during the current season. Of these:
-
6,707 cases have been laboratory confirmed.
-
Around 11,500 additional cases remain under investigation to determine where the infections originated.
How Does Cyclosporiasis Spread?
Cyclosporiasis is caused by a microscopic parasite that usually spreads through contaminated food or water.
Unlike many infectious diseases, it does not spread directly from one person to another.
Common symptoms include:
-
Watery diarrhea
-
Stomach cramps and abdominal pain
-
Nausea
-
Gas and bloating
-
Fatigue
-
Loss of appetite
-
Weight loss
The illness is more likely to cause serious complications in older adults and people with weakened immune systems or underlying medical conditions.
Health Officials Link Some Cases to Contaminated Lettuce
The U.S. Food and Drug Administration (FDA), CDC, and state health agencies are investigating multiple clusters of infections.
Officials have linked one outbreak to iceberg lettuce supplied by Taylor Farms, which has since been recalled. Consumers are advised to avoid recalled products and stay updated on food safety advisories issued by health authorities.
How to Reduce the Risk
Health experts recommend a few simple precautions to lower the risk of infection:
-
Wash fruits and vegetables thoroughly before eating.
-
Drink clean and safe water.
-
Follow food recall notices issued by health authorities.
-
Seek medical attention if severe diarrhea or dehydration develops.
With the number of cases continuing to rise, health authorities are closely monitoring the outbreak and urging the public to follow food safety guidelines to reduce the risk of infection.
