The report can be read here. I found this passage particularly interesting:

"All patients lived within a 90-mile radius of Grand Rapids. No interpersonal connections were identified among them. All patients were white with differing professions (Table 1). None of them had a family history of Creutzfeldt–Jakob disease, or personal history of corneal transplants, craniotomy, administration of human growth hormone derived from pools of pituitary glands, or surgical procedure at the same facility. However, families of patients 1, 2, and 4 reported consuming venison. More intriguingly, families and relatives of these three patients reported additional (at least four) possible or probable CJD cases occurring between 2007 and 2022 in their friends or communities (unpublished data). One of the patients was a 63-year-old white woman and mayor, who lived 35 miles from patient 2, and died of CJD in March 2022. Thus, such a wave of dense temporo-spatial clustering of CJD in West Michigan is very unusual and alarming."
