A diarrhea-causing disease is affecting California at a rate that is double the average, according to recent reports. The specific disease in question is cyclospora, which is currently the focus of multiple new outbreak investigations by the CDC. The CDC is working to determine the cause of these outbreaks, but so far none have been identified.

Further information on the outbreaks and the CDC's investigation can be found through SFGate, a local news source for the Bay Area.
