With more than 1,000 victims confirmed since May 1, the so-called seasonal outbreak of cyclospora in the United States has slowed down, but officials say more people are expected to get sick — and they have not identified the source of the parasite.
Investigators at the Centers for Disease Control and Prevention have identified victims in 40 states, but they are not sure if there is one big outbreak or multiple outbreaks, according to the agency’s most recent update.
