The U.S. Centers for Disease Control and Prevention (CDC) is investigating as a parasite that causes watery diarrhea appears to be spreading just as summer hits its stride.
The CDC earlier this week said it’s looking into an uptick in cyclosporiasis, with the state of Michigan reporting a surge in cases. As of July 1, the CDC reported 145 cases of cyclosporiasis being acquired across 17 states from May 1 through June 16, with 20 people being hospitalized as a result. Those impacted range from age five to 86.
The Michigan Department of Health and Human Services also stated on July 1 that it is “actively investigating a large and growing outbreak of cyclosporiasis.”
“As of Tuesday, June 30, more than 170 cases have been reported in Monroe, Lenawee, Washtenaw, Wayne, Livingston, Shiawassee and Jackson counties in the past nine days,” the news release states. “Typically, Michigan only identifies around 50 cyclosporiasis cases per year.”
What is cyclosporiasis?
According to the Public Health Agency of Canada (PHAC), cyclosporiasis is an illness of the intestines caused by a parasite called cyclospora. The most common way that cyclospora is spread is by “eating food or drinking water that contains the cyclospora parasite.”
“The cyclospora parasite gets in sources of water when feces from infected people enter the water supply,” PHAC states. “Food can then become contaminated when this water is used on crops” and “in food processing and packaging.”
In addition, foods can become contaminated from infected farm workers or food handlers.
This can happen when proper sanitation techniques, such as hand washing, wearing gloves or any other barriers or avoidance of cross-contamination, are not implemented.

Cyclospora can also be found in sewage and untreated water.
The CDC identifies the cyclosporiasis season to be from May 1 through to Aug. 31.
What are the symptoms of cyclosporiasis?
According to PHAC, symptoms of cyclosporiasis may include:
- Watery diarrhea
- Abdominal bloating and gas
- Fatigue (tiredness)
- Stomach cramps
- Loss of appetite
- Weight loss
- Mild fever
- Nausea
When contaminated food or water is consumed, it may take seven to 14 days for symptoms to appear.
If left untreated, symptoms can persist for a few days up to a few months. Most people have symptoms for six to seven weeks but in other cases, symptoms can come and go.
Where is cyclospora most common?
Cyclospora can be found worldwide, according to PHAC, but is most commonly found in tropical and subtropical areas such as:
- Peru
- Cuba
- India
- Nepal
- Mexico
- Guatemala
- Southeast Asia
- Dominican Republic
How can Canadians avoid getting sick?
The Public Health Agency of Canada confirmed to Global News that the agency is not currently investigating any outbreaks in Canada.
Between 2004 and 2019, an average of 238 cases of cyclosporiasis were reported through the Notifiable Disease Surveillance System.
However, a September 2025 research article investigated a total of 5,337 Canadian cases between 2000 and 2022, where adults aged 30 to 59 were “disproportionately affected.”
Although the PHAC states cyclospora “is not common on food and is not in drinking water in Canada,” the agency also says that “food can be a source of cyclosporiasis for Canadians when imported from countries where cyclospora is common” and “can be hard to prevent.”
For those who are travelling, PHAC recommends that Canadians do the following to reduce risk:
- Avoiding food that has been washed in local drinking water
- Drinking water from a safe source
- Eating cooked food and fruit that you can peel yourself
Basil, cilantro, raspberries, blackberries, Mesclun lettuce, snow and snap peas, and pre-packaged salad mixes are some of the imported foods that have been linked to the parasite.
Canadians at the greatest risk of developing cyclosporiasis are travellers to high-risk countries who either eat fresh produce or drink untreated water, while young children, older adults and those with a weakened immune system are at higher risk for longer, more severe illnesses.
After 11 years of explosive diarrhea from the mouths of the Liberal Party, Canadians should be able to weather through this quite easily.
“A parasite causing diarrhea is spreading in U.S.”
That parasite is similar to the political situation there. Trump and his buddies, like Matthew Moroun, have been sucking American citizens’ finances dry ( with tariffs and high prices for food and fuel) while pretending to represent them.
The word “maga” means “easily fooled idiot” in Nigerian Pidgin.
“A people that elect corrupt politicians, imposters, thieves and traitors are not victims… but accomplices,”
Close the Gordie Howe bridge!
Oh wait…
Nice. You can name the Countries where it can be found. You can name the symptoms it causes. But you can’t name the 17 US States where it is spreading according to this story. Try harder Global.
There must be a different parasite that causes President Trump to spew verbal diarrhea…
trumpitus.
It can affect the brain too like Les below.
Diarrhea out of both ends at once.
Is it called Trump?
Sounds like a politician parasite. They are giving everyone the shats. Truly, N. America is no longer the safe bastion it was.
Cancer on the rise, sickness that debilitate and kill. Gee, wouldn’t be because RFK Jr has axed research into these areas in favor of his hillbilly medicine. A crack/heroine addict has the mantle of disease control and health. Yikes. No wonder folks are dying and cancer is rampant.
CALLED THE “TRUMP BUG”
trump??
Strange, I get these exact symptoms whenever I hear an NDP/liberal speak.
