(NEW YORK) — Cases of cyclosporiasis, an intestinal infection caused by a parasite, are currently being reported in nearly three dozen states, according to an ABC News tally.
As of Friday, at least 2,844 cases have been reported in 32 states, data from the Centers for Disease Control and Prevention (CDC) and state health departments show.
The CDC said the true number of people sick with cyclosporiasis is likely higher than the reported figure because some people recover without medical care and are not tested for the parasite.
Most cases are currently being reported in Michigan with 1,562 as of Friday, according to the Michigan Department of Health and Human Services (MDHHS). At least 44 people have been hospitalized in the state.
This is 31 times higher than the approximately 50 cases that Michigan sees every year, according to the health department.
Michigan health officials previously told ABC News that the working hypothesis is the outbreak is linked to food contamination but, so far, no produce, grower or supplier has been identified.
The parasite usually spreads through food or water contaminated with feces, according to the 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, the CDC says.
New York is reporting the second highest number of cases at 394, followed by Ohio at 364, according to data from both state health departments. Meanwhile, Illinois and Florida are each reporting more than 100 cases, according to their respective health departments.
The most common symptom of cyclosporiasis is watery diarrhea “with frequent and sometimes explosive bowel movements,” according to the CDC. Other symptoms nay include nausea, vomiting, abdominal pain or bloating.
The time between becoming infected and showing symptoms is typically about one week but can range from two days to two weeks, the CDC says. The lag can make it difficult to trace back what may have infected someone, doctors previously told ABC News.
Cyclosporiasis is treated with the oral antibiotic trimethoprim-sulfamethoxazole (TMP-SMX), commonly sold as Bactrim, Septra and Cotrim, and taken for 10 days, according to the CDC.
The agency says 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.
Additionally, the CDC recommends washing hands thoroughly with soap and water before handling or preparing raw fruits and vegetables.

(NEW YORK) — Multiple states are reporting an increase in cyclosporiasis cases, an intestinal infection caused by a parasite.
Health officials in Michigan have reported more than 1,200 cases and, in neighboring Ohio, cases have topped 170.
Here’s what you need to know about the infection, including how it spreads, how it’s diagnosed and how to treat it.
What is Cyclosporiasis?
Cyclosporiasis is an intestinal infection caused by the microscopic parasite Cyclospora cayetanensis, also known as Cyclospora, according to the Centers for Disease Control and Prevention (CDC).
The infection affects the small intestine and can cause watery diarrhea with sometimes “explosive” bowel movements, according to the federal health agency.
Other symptoms can include cramping, bloating, low-grade fever, nausea and vomiting.
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.
How it spreads
The parasite usually spreads through food or water contaminated with feces, according to the 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.
How the infection is diagnosed
A healthcare provider will diagnose cyclosporiasis by testing stool samples, according to the CDC.
Patients may have to submit several stool samples on different days to detect the parasite because laboratory tests may have a hard time detecting Cyclospora.
The CDC says a patient’s healthcare provider will need to specifically request testing for the parasite.
How cyclosporiasis is treated
Cyclosporiasis is treated with the oral antibiotic trimethoprim-sulfamethoxazole (TMP-SMX), commonly sold as Bactrim, Septra and Cotrim, and taken for 10 days, according to the CDC.
The CDC says most people with healthy immune systems will eventually recover without treatment, but if left untreated, patients may be sick for a few days to a month or longer.
How to prevent infection
It’s unclear exactly how Cyclospora contaminates food and water, according to the CDC.
The agency says 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.
Additionally, the CDC recommends washing hands thoroughly with soap and water before handling or preparing raw fruits and vegetables.

(NEW YORK) — A Legionnaires’ disease cluster in New York City is growing, with 36 cases now confirmed, according to health officials.
As of Wednesday, there have been at least 22 hospitalizations and no deaths, according to the New York City Department of Health (NYC Health).
The cluster has affected the Upper East Side neighborhoods of Carnegie Hill and Yorkville, the department said.
In an earlier notice to the two neighborhoods, NYC Health said it believes the likely source of the bacteria is a cooling tower in the area, which sprays a mist that contains the bacteria. All area cooling towers were being tested for the bacteria, NYC Health said then.
There is no issue with any building’s plumbing system and residents in the affected areas can continue to drink tap water, bathe, shower, cook and use their air conditioners, NYC Health further said in the notice.
On Tuesday, New York Mayor Zohran Mamdani said his administration was implementing measures to publicly identify the specific buildings suspected as being sources of Legionella bacteria and require owners to clean cooling towers quickly.
Legionnaires’ disease is a severe form of pneumonia caused by inhaling the Legionella bacteria in small droplets of water mixed in the air or by contaminated water otherwise entering the lungs.
The bacteria are found naturally in fresh water but in amounts that generally don’t lead to disease. The bacteria typically grow best in warm water and in warm to hot temperatures, according to the Centers for Disease Control and Prevention (CDC).
The disease does not generally spread from person to person but infections can occur if the bacteria get into a building’s water supply, including in shower heads, sink faucets, hot water tanks, heaters, cooling towers and other plumbing systems.
Legionnaires’ disease has increased in prevalence over the last decade, reaching a peak in the U.S. of 2.71 cases per 100,000 in 2018, the CDC said. Cases declined during the first year of the COVID-19 pandemic and then rebounded in 2021.
Although most people recover from Legionnaires’ disease with antibiotics, certain patients – including those who are immunocompromised or who suffer from chronic lung diseases – can develop complications that can be fatal.
About one out of every 10 people who develop Legionnaires’ disease will die due to complications, according to the CDC. Among those who develop Legionnaires’ disease at a healthcare facility, about one of every four people will die, the CDC says.

(LANSING, Mich.) — Reported cases of cyclosporiasis, an intestinal illness caused by a parasite, have topped 1,200 in Michigan, local health officials said Thursday.
Since June 22, at least 1,251 cases have been confirmed, according to the Michigan Department of Health and Human Services (MDHHS) . At least 36 people have been hospitalized.
Typically, the state sees about 50 cases per year.
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.
Michigan is not the only state reporting cases. 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.

(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.

(DETROIT) — Cases of a parasitic infection are continuing to rise in at least two states, local health officials said.
As of July 6, nearly 700 cases of cyclosporiasis, an intestinal infection, were confirmed, an official from the Michigan Department of Health and Human Services (MDHHS) told ABC News on Monday. This is an increase from the roughly 300 cases reported on Thursday.
The 678 cases have predominantly been confirmed the southeast region of Michigan including Wayne County, where Detroit is located.
Typically, the state has 50 cases per year, meaning cases are currently about 13.5 times higher than on average.
Dr. Natasha Bagdasarian, an infectious disease physician, epidemiologist and the chief medical executive for the state of Michigan, described the 678 figure as a “moving target,” meaning that cases are likely to continue rising.
“There is a significant lag time between exposure to contaminated produce or contaminated materials and development of symptoms,” she told ABC News. “So it can take a week, sometimes even two weeks between exposure and development of symptoms.”
She added that there may be some infected individuals who are only now reading news reports and getting tested, so there may be even more delayed diagnoses.
Additionally, in Ohio, there were 177 cases of cyclosporiasis as of July 2, Ken Gordon, press secretary for the Ohio Department of Health’s communications office, confirmed to ABC News.
Cases have been confirmed across 43 counties in Ohio so far this year, according to Gordon. Most of those cases — 171 — were reported since June 20.
Meanwhile, the Centers for Disease Control and Prevention (CDC) reports 145 cases have been detected in 17 states since May 1, excluding Michigan, as of June 16, with at least 20 people hospitalized. No deaths have been reported.
The CDC said cases ranged between age 5 and 86, with a median age of 42, and 61% were female.
So far, no cases have been linked between states and health officials are still investigating if there is a common source of the outbreak in Michigan.
The parasite usually spreads through food or water contaminated with feces, according to the 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 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.
Bagdasarian said MDHHS’s working hypothesis is that the outbreak is linked to contaminated produce, but it’s unclear which produce, how long it has been on the shelf or where it’s been distributed.
“We are making sure that we’re issuing guidance to the public as well as to restaurants and commercial kitchens so that folks know the safest way to eat produce right now,” she said. “If folks are making the switch and consuming all of these products as safely as possible, that could mean that we are still seeing cases where people were exposed.”
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.
Since cyclosporiasis symptoms can resemble other illnesses, it may be hard for a patient to determine what they are infected with.
While a traditional stomach bug will have symptoms that typically disappear within 24 to 48 hours, cyclosporiasis symptoms may last for days or even weeks, Bagdasarian noted.
“If you believe that you could have cyclosporiasis, it’s really important to see your healthcare provider and to mention cyclosporiasis, just in case they haven’t heard about this outbreak happening right now, and ask for stool testing, because not all stool testing routinely will include cyclosporiasis,” she said.
The CDC said the infection is very unlikely to spread from person to person because it takes at least one to two weeks outside the body for the parasite to become infectious after someone passes a bowel movement.
Local and federal authorities are working to find the cause of cases in various states and to see if there are any connections. So far none have been identified.
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.
The CDC recommends 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.
“Grabbing a scrub brush can also be helpful,” Dr. Darien Sutton, an emergency medicine physician and ABC News medical correspondent, said on “Good Morning America Weekend” on Sunday. “And an important note here, this type of parasite doesn’t easily go away with alcohol-based hand sanitizer. So, good old handwashing is really key here.”

(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.

(GENEVA) — The World Health Organization (WHO) said on Thursday that the hantavirus outbreak linked to a cruise ship is over.
It came after the final contact of a person exposed to the virus on the cruise ship completed their quarantine period, according to WHO Director-General Dr. Tedros Adhanom Ghebreyesus. The recommended quarantine and monitoring period for hantavirus exposure is 42 days.
The individual tested negative and returned home. No further cases have been reported since May 25, Tedros said during a media briefing.
As of Thursday, there have been a total of 13 cases of hantavirus — 12 confirmed and one probable — and three deaths, of which at least two have been confirmed, according to the WHO. All cases have been passengers or crew members on the ship.
Tedros said more than 650 contacts were identified and followed up by health authorities in 33 countries and territories.
“Although the outbreak is over, WHO will continue working with governments and partners to advance our understanding of this outbreak and of hantavirus more generally,” Tedros said. “We are also coordinating a study involving 21 countries to understand how the disease develops, which will support the development of diagnostics, therapeutics and vaccines for future outbreaks.”
Last week, quarantine ended for the 18 Americans who were cruise ship passengers on the MV Hondius and exposed to hantavirus.
The WHO said it received notification on May 2 of a cluster of “severe acute respiratory illness” aboard the MV Hondius, including two deaths and one critically ill passenger
The working hypothesis behind the cluster is that the first case was infected with hantavirus while on land, before boarding the cruise ship, according to the WHO.
At least 11 confirmed cases tested positive for Andes virus, a rare strain of hantavirus, and the only one that is known to transmit between people, according to the Centers for Disease Control and Prevention.

(NEW YORK) — A record number of West Nile virus cases have been recorded for this time of year, the Centers for Disease Control and Prevention (CDC) warned on Wednesday ahead of the upcoming holiday weekend.
At least 48 cases of West Nile have been reported so far this year compared to an average of 10 typically by the end of June. This is the highest number of infections reported at this point in year since 2004, according to the federal health agency.
Additionally, at least 23 states are reporting West Nile activity, which is the highest number recorded over the last 10 years, CDC data shows.
The illness is the leading cause of mosquito-borne disease in the contagious U.S., with several thousand cases and over 100 deaths reported on average each year.
With millions gathering outside for Fourth of July, the CDC is urging Americans to take precautions and reduce their risk of mosquito bites.
Since 1999, the disease has killed more than 3,300 Americans. Cases have historically peaked in August and are mostly reported from June through October.
While many people infected do not develop symptoms, about one in five do. Symptoms include fever, headache, body aches, vomiting, diarrhea or rash, according to the CDC. Most symptoms soon disappear, though weakness and fatigue may last for weeks or months.
Fewer than 1% of people infected develop severe illness that affects the central nervous system, including inflammation of the brain (encephalitis) and the membranes around the brain and spinal cord (meningitis), the CDC says.
Risk of severe disease, hospitalization and death increase with older age; certain medical conditions including cancer, high blood pressure and kidney disease; and a weakened immune system.
There are currently no vaccines for West Nile virus, nor disease-specific treatments. The CDC recommends rest, fluids and over-the-counter medications to treat the infection. Those with severe illness may need to be hospitalized and receive additional support treatments, such as intravenous fluids.
