NH DHHS: Two cases of cyclosporiasis confirmed in the state in 2026

The New Hampshire Department of Health and Human Services (NH DHHS) has officially confirmed two cases of cyclosporiasis within the state during 2026. This local development is part of a much larger national health event, as reports indicate a parasite outbreak linked to produce has sickened hundreds of people across 31 different states. The scale of the outbreak is evident in New York, where CBS News reports that the number of cyclosporiasis cases continues to grow and has now reached a total of 470 statewide. Coverage of the outbreak emphasizes the severe nature of the symptoms and the wide geographic spread of the infection. According to reports from Axios, the illness—described as a stomach bug causing explosive diarrhea—has been reported in Texas and has reached the Tampa Bay area.

Other outlets, including KTLA and Your Local Epidemiologist, have focused on the explosive nature of the foodborne outbreak and its direct link to produce items. The reporting highlights a coordinated public health crisis affecting multiple regions simultaneously. To understand the current stakes, readers must note that cyclosporiasis is caused by a parasite and is frequently associated with contaminated food products. The current outbreak is significant because of its vast reach, spanning 31 states and resulting in hundreds of illnesses. The rapid growth of cases in New York, reaching 470, underscores the potential for high infection rates when a contaminated produce source enters the commercial supply chain, as highlighted by the reports from CBS News and KTLA.

Future developments to monitor include whether health officials identify the specific produce items responsible for the transmission. Based on the current coverage, the focus remains on the increasing case counts in New York and the spread into areas like Tampa Bay and Texas. Watch for updates from the NH DHHS regarding additional cases in New Hampshire and further data from national health agencies as they track the parasite's impact across the 31 affected states.
