A parasite is causing hundreds of cases of serious stomach and intestinal illness across several states, including Texas, according to the U.S. Centers for Disease Control and Prevention. The parasite, known as Cyclospora cayetanensis, is microscopic, but the infection’s symptoms can be more obvious.

What is Cyclospora cayetanensis?

Cyclospora cayetanensis is a parasite that spreads when people ingest contaminated food or water. Produce has been linked to many of the reported cases, the CDC said. The CDC is reporting at least 145 cases in 17 states, including Texas. No deaths have been reported, but 20 people have been hospitalized.

San Antonio Metro Health said it is aware of the outbreak, but no cases have been reported in San Antonio at this time. There is no evidence yet of a common link connecting the confirmed cases, according to health officials.

The most common symptom is severe diarrhea, described as profuse or explosive. Other symptoms can include stomach cramps, bloating, increased gas and nausea. Many people with healthy immune systems recover without treatment, but the infection can last from a few days to a month or longer, according to the CDC.
