(NEW YORK) — Reported cases of cyclosporiasis, an intestinal illness caused by a parasite, have surpassed 3,000 in Michigan, the state’s health department said on Tuesday.

Cases jumped more than 600 since Monday. There have been a total of 3,309 cases since June 22, according to the Michigan Department of Health and Human Services (MDHHS). At least 44 people have been hospitalized. Michigan typically sees about 50 cases per year.

Most cases have been reported in southeastern Michigan, including Wayne County, where Detroit is located, according to MDHHS.

On Monday, Michigan health officials said lettuce or salad greens could be the source of illnesses in the state.

MDHHS data shows that most cases have been among adults, with 30 to 39 year olds making up the highest share.

The outbreak was first identified on June 29, when the Monroe County Health Department announced it was investigating a cluster of cases.

Michigan health officials previously told ABC News the outbreak could be linked to food contamination. So far no produce, grower or supplier have been identified.

Earlier this month, MDHHS sent out recommendations to restaurants and other commercial kitchens in southeast Michigan to reduce risks of exposure.

The parasite usually spreads through food or water contaminated with feces, according to the Centers for Disease Control and Prevention. It does not typically spread person-to-person. 

Foodborne outbreaks of cyclosporiasis in the past have been linked to various types of imported fresh produce, such as raspberries, basil, snow peas, mesclun lettuce and cilantro, according to the CDC.

At least 31 other states have reported cases of cyclosporiasis, according to an ABC News tally, analyzing CDC data and state health department data.

As of Friday, New York has reported the second-highest number of cases at 470 cases since May 1, followed by Ohio at 364, state health officials told ABC News. Meanwhile, Illinois and Florida are each reporting more than 100 cases as of Friday, according to their respective health departments.

The CDC said it has confirmed 843 domestic cases from May 1 to July 9. The agency wrote on its website that it is “aware that states are likely to report higher case counts of cyclosporiasis than reflected in CDC data and is working closely with states to update numbers as additional cases are confirmed.”

The agency said it expects a six-week reporting lag between illness onset and case reporting to the CDC as it receives and reviews the data. 

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.

Republican senators release Fauci’s text messages discussing safety of Covid vaccine and pregnancy

By CNN
(CNN) — Two Republican senators have released the first batch of text messages retrieved from Dr. Anthony Fauci’s former government phone as part of an investigation into his leadership and actions during the Covid-19 pandemic – including messages in which he discusses the possible risks and safety of the vaccine during pregnancy.Sens. Ron Johnson of Wisconsin and Rand Paul of Kentucky released the texts publicly online Monday, after the Department of Health and Human Services (HHS) provided Fauci’s iPhone to a Senate subcommittee investigating him.The phone contained more than 34,000 messages and 522 voicemails, said the senators in a news release. They published screenshots showing a fraction of these – 11 texts sent during Fauci’s tenure as director of the National Institute of Allergy and Infectious Diseases (NIAID).In one exchange on January 25, 2021, Dr. Vivek Murthy, then a member of President Joe Biden’s Covid advisory board, asked about any potential risk to those who are pregnant, or whether Fauci knew of any “data or theoretical reason why vaccinating early vs late in pregnancy would be preferred.”Fauci responded that there was “no data or theoretical reason to believe that vaccinating early versus later in pregnancy would be preferred.”Then he added: “Since many people have significant cytokines storm and fever after the 2nd dose, this theoretically could be associated with miscarriage in the 1st trimester.”Dr. Rochelle Walensky, then-director of the Centers for Disease Control and Prevention (CDC), replied, “Definitely a good point, esp after dose two.”In another exchange a day later, according to the screenshots released, Fauci said that any vaccine with limited data on pregnancy should be carefully considered. “One must weigh the potential risks against the benefits,” he wrote, pointing out that a Covid infection could be “especially” serious in pregnancy.Though pregnant individuals were not included in vaccine trials, more than 10,000 had been vaccinated since the government issued an Emergency Use Authorization for the vaccine – and “no issues have arisen,” he wrote in a text.CNN has reached out to Fauci, Murthy and Walensky for comment.The CDC formally recommended on August 11, 2021, that pregnant people receive the vaccine after analyzing data and finding no increased risks of miscarriage or other safety concerns related to the shot.The CDC also warned during the pandemic that pregnant people were more likely to get severely ill compared to those who were not pregnant, according to an archived page from the agency’s website.Studies have since shown that the vaccines were safe during pregnancy, and that serious adverse reactions are rare. The American College of Obstetricians and Gynecologists still recommends, as of this spring, that individuals who are pregnant or will be pregnant during the fall or winter should receive annual Covid-19 vaccines.In a news release, Johnson and Paul said their staff were reviewing the rest of the information on Fauci’s phone, and would publicly release them “as soon as possible.” The texts released on Monday “could have an immediate impact of public health and the principle of informed consent,” they said.The news release also listed several further public statements made by Fauci and other health officials in the months following the text exchange, recommending pregnant people receive Covid-19 vaccines.Battles on the HillPaul, who chairs the full Senate Homeland Security and Governmental Affairs Committee, has long clashed with Fauci, who he subpoenaed in June to appear before Congress.He and other prominent Republicans accuse Fauci of covering up the origins of the pandemic, and of lying and misrepresenting data during the Covid-19 response – though they’ve yet to present clear evidence of such an alleged cover-up.Republican members of the Senate subcommittee voted last week to hold Fauci in contempt of Congress after he invoked the Fifth Amendment more than 100 times in a hearing, refusing to answer questions over concerns his responses would be used in an attempt to bring charges against him.Democrats pointed to the hearing as the latest example of Republicans spending years trying to deflect pandemic criticisms away from President Donald Trump and toward Fauci.“The campaign to vilify you, Dr. Fauci, is just one part of this larger campaign against science and facts — a campaign that has made Americans less safe,” said Sen. Richard Blumenthal, a Democrat from Connecticut.Ahead of that hearing, the committee also released more than 1,100 pages of Fauci’s personal diary from 2019 to 2022.Neither HHS nor Paul’s committee alerted Fauci ahead of time that they had obtained his diary and that they planned to publish it in full, according to a person familiar with the matter.The diary entries narrated Fauci’s growing concerns about Covid-19, frustrations with the government response and conflicting relationships with both Trump and Biden administration officials.The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
