UPPER MICHIGAN. (WLUC) – As of Wednesday afternoon, the Western U.P. Health Department says there are no active cases of cyclosporiasis, a parasite-caused diarrheal illness, in the U.P.
The Michigan Department of Health and Human Services has been investigating the spread of the illness throughout Michigan, but the Western U.P. Health Department Director Dr. Robert Van Howe says there are no active cases in the U.P. as of Wednesday.
Van Howe told TV6 over the phone that there was one case in Houghton County a couple of weeks ago, but that case is no longer active and that individual is no longer in the area.
The MDHHS says the source of the outbreak has not been identified, and the agency is working with local health departments and partners to investigate cases and provide updates as more information becomes available.
As of 10:30 a.m. on Wednesday, July 8, the total cases in Michigan are at 992 reports since Monday, June 22. For context, Lynn Suftin with the MDHHS said the state usually sees about 50 cases in a typical year.
Suftin also shared a county-level breakdown of the caseload in a Wednesday afternoon email.
Suftin says the numbers are provisional data as far as the county of residence, and the numbers are subject to change as the investigation continues. This means that the numbers are constantly fluctuating and should not be interpreted as real-time case numbers.
Cyclosporiasis causes sudden and ongoing diarrhea, loss of appetite and weight, abdominal cramps and bloating, nausea and low-grade fever.
Anyone experiencing gastrointestinal illness, such as sudden and ongoing diarrhea, should contact their health care provider and their local health department.
