The CDC reported in its July 23 report that the number of cases of domestically acquired Cyclosporiasis has increased from the previous month and remains elevated in the US on May 1, 2019. As of July 23, 2019, 580 laboratory-confirmed cases of Cyclosporiasis were reported to CDC by 32 states (see ma), in people who became ill since May 1, 2019, and who had no history of international travel during the 14 days before illness onset. At least 38 people were hospitalized; no deaths were reported. At this time, multiple clusters of cases associated with different restaurants or events are being investigated. One outbreak is linked to basil imported from Mexico. The CDC could not link many cases to an outbreak, in part because of the lack of validated molecular typing tools for C. cayetanensis. @ https://www.cdc.gov/parasites/cyclosporiasis/outbreaks/2019/a-050119/index.html
