(LANSING, Mich.) — Reported cases of cyclosporiasis, an intestinal illness caused by a parasite, are nearing 1,000 in Michigan, local health officials said Wednesday.
Since June 22, at least 992 cases have been confirmed, a spokesperson from the Michigan Department of Health and Human Services (MDHHS) told ABC News. At least 36 people have been hospitalized.
Typically, the state sees about 50 cases per year, meaning cases are nearly 20 times higher than on average.
Dr. Natasha Bagdasarian, an infectious disease physician, epidemiologist and the chief medical executive for the state of Michigan, told ABC News earlier this week that the department’s working hypothesis is the outbreak is linked to contaminated produce.
The parasite usually spreads through food or water contaminated with feces, according to the Centers for Disease Control and Prevention (CDC).
Foodborne outbreaks of cyclosporiasis have been linked to various types of imported fresh produce, such as raspberries, basil, snow peas, mesclun lettuce and cilantro, according to the CDC.
The MDHHS spokesperson said on Wednesday that no specific produce, grower, supplier or type of produce has been identified as the source.
The CDC said there have been 145 cases detected in 17 states since May 1, excluding Michigan. No deaths have been reported.
The CDC said patients’ ages cases ranged from 5 through 86 and 61% were female.
Some patients do not experience any symptoms but, for those who do, the most common symptom is “explosive watery diarrhea,” doctors previously told ABC News. Other symptoms can include cramping, bloating, low-grade fever, nausea and vomiting, the doctors said.
The CDC says it takes about one week from the time of infection to become symptomatic, but that time can range from two days to two weeks.
Because cyclosporiasis symptoms can resemble other illnesses, it may be hard for a patient to determine the cause.
“Anyone experiencing gastrointestinal illness, such as sudden and ongoing diarrhea, should contact their health care provider and their local health department,” the MDHHS spokesperson told ABC News in an email.

(NEW YORK) — Fewer than 49% of Americans can afford healthcare, the lowest rate since tracking began in 2021, according to Gallup data released Thursday.
In a single year, roughly 2.8 million people no longer identified as being “Cost Secure” meaning they could no longer afford access to quality care or pay for visits and prescriptions, according to the data. Worry about future healthcare costs, including visits and prescriptions, amongst Americans is also at an all-time high of over 40%, according to Gallup.
Gallup developed what it calls the “Healthcare Affordability Index,” which is sponsored by West Health, in 2021 drawing on self‑reported experiences from nationally representative surveys. The latest data comes from a study conducted between October and December of 2025, according to Gallup and West Health.
Healthcare has become a financial burden across income levels, according to the new data. According to the index, one in three upper-middle income households ($120,00 to $180,000) are not cost secure, nor are one in five households earning above $180,000.
Young adults, aged 18-29, have experienced the sharpest decline in ability to afford healthcare with those identifying as “cost secure” dropping 7 percentage points in a year.
Women continue to trail behind men when it comes to affording healthcare.
Between 2021 and 2024 the difference between men and women being able to afford care was 9% but in 2025 the gap widened to 15%, making it the largest gender gap in healthcare affordability on record.
Healthcare and inflation continue to rise with healthcare spending reaching $5.3 trillion in 2024. This, in part, is due to hospital prices increasing to 3.4% in 2024, the fastest rate increase since 2007, and insurance premiums going up by 20% after the expiration of subsidies under the Affordable Care Act.
With many Americans experiencing significant healthcare-related financial challenges, studies show that this can lead to significant consequences, including delaying or deferring care, leading to worse health overall.

(NEW YORK) — A rare rodent-borne disease may be behind an outbreak aboard a cruise ship.
The World Health Organization (WHO) says there has been one laboratory confirmed case and five suspected cases. Of those six people, three have died.
The deaths occurred between April 11 and May 2 and the variant of hantavirus identified in at least one patient who is currently in intensive care, according to the WHO.
The WHO said on Monday that investigations into the deaths and illnesses are ongoing, including further laboratory testing.
The outbreak was reported on the MV Hondius, run by Oceanwide Expeditions, which was traveling between Argentina and the Canary Islands via Cape Verde.
Currently, the ship is off the coast of Cape Verde with 149 people on board representing 23 different nationalities, Oceanwide Expeditions said in a press release on Monday.
Here’s what you need to know about the outbreak, what hantavirus is and how it spreads.
Timeline of the outbreak
South African health officials said in a statement on Monday that the first two deaths occurred in a married couple from the Netherlands. The 70-year-old male passenger became ill first with a fever, headache, abdominal pain and diarrhea. He passed away upon arriving in St. Helena, a British territory in the South Atlantic Ocean, according to the statement.
The deceased passenger’s wife, 69, collapsed at Johannesburg O.R. Tambo International Airport while trying to connect to fly home to the Netherlands, according the country’s department of health. She was taken to a medical facility in nearby Kempton Park, where she also passed away, the statement said.
Another patient, a British national, fell ill while the ship was traveling from St. Helena to Ascension, also a British territory, according to the statement.
“Despite medical treatment provided to him at Ascension, his condition did not improve and necessitated his medical evacuation to a South African private health facility in Sandton for further medical management,” the statement said.
The patient is currently in critical condition in isolation but receiving medical attention, according to health officials, who said his laboratory test results came back positive for hantavirus.
Oceanwide Expeditions said in Monday’s press release that the first death occurred on April 11 and that the company learned of the second death on April 27. The British national also fell in on April 27.
A third passenger of German nationality died on May 2 from causes not yet known, according to Oceanwide Expeditions.
Meanwhile, two crew members – one of British nationality and one of Dutch nationality – are on board the MV Hondius with acute respiratory symptoms. One has a mild illness and one has severe symptoms, with both requiring urgent medical care, Oceanwide Expeditions said, adding that no other people with symptoms have been identified.
The company said that hantavirus has not been confirmed in the two patients still on board the ship, nor has it been confirmed as the cause of the three passenger deaths.
“Strict precautionary measures are in process on board, including isolation measures, hygiene protocols and medical monitoring. All passengers have been informed and are being supported,” the company said. “We understand the considerable interest and concern and will share new information as soon as it has been verified.”
WHO Director-General Dr. Tedros Ghebreysus said in a post on X on Sunday that the organization is working closely with both member states and ship operators in response to the suspected hantavirus cases.
“WHO is facilitating medical evacuation of two symptomatic passengers, conducting a full risk assessment, and supporting affected people onboard,” Ghebreysus wrote.
The viruses cause two syndromes: hantavirus pulmonary syndrome (HPS) and hemorrhagic fever with renal syndrome (HFRS). HPS is mostly found in the Western Hemisphere, including the U.S., and HFRS is mostly found in Europe and Asia.
Surveillance for hantavirus in the U.S. began in 1993 during an outbreak in the Four Corners region, where Arizona, Colorado, New Mexico and Utah meet, the CDC said. Between 1993 and the end of 2023, 890 cases of hantavirus disease have been reported in the U.S., according to the CDC.
Hantavirus became more widely known after being identified as the cause of death of the wife of actor Gene Hackman after the couple was found dead at their New Mexico home in February 2025.
How does hantavirus spread?
Hantaviruses are usually spread through rodents, including rats and mice, mostly from exposure to urine, droppings or saliva. Although the viruses can spread through a rodent bite or scratch, such infection is rare, the CDC says.
Hantaviruses may also spread from person to person but that also is rare and only suspected for one subtype from South America, according to the WHO.
What are the hantavirus symptoms?
HPS symptoms typically appear from one to eight weeks after contact with the virus, with early signs including fever, fatigue and muscle aches, according to the CDC. Half of HPS patients will experience headaches, chills, dizziness, nausea, vomiting, diarrhea and abdominal pain.
The CDC says that between four and 10 days after the initial phase of illness, the late symptoms will appear, including coughing, shortness of breath and tightness in the chest as the lungs fill with fluid.
About 38% of people who develop HPS respiratory symptoms may die from the disease, according to the CDC.
Symptoms of HFRS usually develop one to two weeks after exposure and typically include intense headaches, fever, chills, back pain, abdominal pain, nausea and vomiting, the CDC says.
Later symptoms may include low blood pressure, lack of blood flow, internal bleeding and acute kidney failure. Depending on the virus causing the infection, fatality among infected humans can range from less than 1% to as high as 15%, the CDC says.
What hantavirus treatments are available?
No specific treatment is available for hantavirus infection, with the CDC recommending patients receive supportive care such as rest, hydration and treatment of symptoms.
Because HPS can cause breathing difficulties, patients may need breathing support, such as intubation, the CDC says.
Because HFRS can disrupt kidney function, infected patients may need dialysis to remove toxins from the blood, according to the CDC.

(MICHIGAN) — A “large and growing” outbreak of a parasitic infection is spreading in Michigan, health officials warned this week.
As of Thursday, more than 300 cases of cyclosporiasis, an intestinal infection, have been confirmed, the Michigan Department of Health and Human Services (MDHHS) told ABC News. Typically, the state only sees about 50 cases per year, according to MDHHS.
The parasite usually spreads through food or water contaminated with feces, according to the Centers for Disease Control and Prevention (CDC).
“We are working closely with our state and local partners to identify the source of this outbreak that is making so many people ill as quickly as possible,” Lynn Sutfin, public information officer for MDHHS, told ABC News.
The outbreak comes as the CDC reports 145 cases have been infected in 17 states, excluding Michigan, as of June 15, with at least 20 people hospitalized.
The CDC, the Food and Drug Administration, state and local authorities are investigating several clusters of cyclosporiasis cases in multiple states.
Doctors told ABC News that cases usually start in May, so the Michigan outbreak occurred during the time or year when public health specialists typically would see a rise in cases. However, the number of cases in Michigan is particularly high, doctors said.
Dr. Peter Chin-Hong, an infectious diseases specialist and associate dean for regional campuses at the University of California, San Francisco, told ABC News that in years past, the U.S. used to see many cases cyclosporiasis acquired outside of the U.S, or from imported vegetables and fruits.
“But now we’re starting to have more domestic cases as well,” Chin-Hong said.
Foodborne outbreaks of cyclosporiasis have been linked to various types of imported fresh produce, such as raspberries, basil, snow peas, mesclun lettuce and cilantro, according to the CDC. The agency further said it takes about one week from the time of infection to become symptomatic, but that time can range from two days to two weeks.
Some patients do not experience any symptoms but, for those who do, the most common symptom is “explosive watery diarrhea,” Dr. Zoe Weiss, director of clinical microbiology at Tufts Medical Center, told ABC News.
Other symptoms can include cramping, bloating, low-grade fever, nausea and vomiting, Weiss said.
“Though in most cases this illness causes discomfort from cramping, bloating and watery diarrhea, we are concerned about individuals who may be immunocompromised due to cancer treatment or an organ transplant as the effects may be more severe,” Sutfin from MDHHS said.
Weiss said the infection is very unlikely to spread from person-to-person “because the parasite is passed in the stool, and then it requires days to weeks of formulation in the environment before it can become infectious.”
Chin-Hong said that oftentimes people dismiss watery diarrhea, but it is important to get a diagnosis to get treatment as soon as possible.
Cyclosporiasis is treated with the oral antibiotic trimethoprim-sulfamethoxazole (TMP-SMX), commonly sold as Bactrim, Septra and Cotrim, taken for 10 days, according to the CDC.
Doctors told ABC News that people can prevent infection by thoroughly washing produce, cutting away bruised or damaged parts of fruits and vegetables, and refrigerating pre-prepared or pre-cut produce.
“If you’re in an area that’s been affected and you have sudden ongoing watery diarrhea, you should definitely seek a physician and get treatment,” Weiss said.
