Federal health officials are monitoring a growing number of cyclosporiasis cases this summer, with 145 infections reported across 17 states as of mid-June 2026.

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.

Only New York has more cases of Cyclospora nationwide.

The parasite, Cyclospora, which commonly triggers watery diarrhea and other gastrointestinal symptoms, has infected more than 140 people across multiple states.

People usually become infected from eating contaminated food or water.

The study found that the vaccine reduced the risk of emergency department visits and hospitalizations among healthy adults by about half last winter.
