The Center for Infectious Disease Research and Policy is reporting that U.S. federal health officials have joined with officials in 13 states to investigate a spike in Cyclospora illnesses, with 125 confirmed or probable cases reported and no specific food item implicated so far.

Texas health officials have been investigating a recent surge of infections, and an outbreak investigation is underway in Maine, with Massachusetts also probing an increase in lab-confirmed cyclosporiasis cases, the CDC said in an e-mail to CIDRAP News. As of today, it said, those 3 states, 10 others, and New York City have reported cases. The other states are Connecticut, Florida, Georgia, Illinois, Maryland, Montana, New Jersey, New York, Oregon, and Tennessee.

News of a multistate increase in Cyclospora illnesses follows the recent launch of the investigation in Texas. Over the last months the Texas Department of State Health Services (TDSHS) has learned of 61 cases around the state, which prompted a recent alert to Texas healthcare providers. No common source has been identified.
