Cyclosporiasis cases continue to rise in New Hampshire

Public health reports indicate a significant increase in cyclosporiasis cases across the New England region. In New Hampshire, the number of reported cases has continued to rise throughout the current year. According to data shared via Facebook, there have been 147 cases reported statewide so far in 2026. This figure represents the highest annual total for the state since 2019, a year in which more than 200 cases were confirmed. The spread of the illness is not limited to one state, as reports indicate that Connecticut is also experiencing a surge in confirmed infections. Coverage from various outlets emphasizes the regional nature of the outbreak.

These reports collectively suggest a multi-state health concern affecting residents in both New Hampshire and Connecticut. To understand the current stakes, it is necessary to look at the historical context provided by the coverage. The current surge in New Hampshire is being compared to a previous peak in 2019, which remains the benchmark for high infection rates in the state with over 200 confirmed cases.

The current total of 147 cases in 2026 indicates that the state is approaching those previous levels. The mention of specific businesses taking precautions, such as the deli in Vernon, suggests that health officials or business owners are concerned about potential vectors of transmission within the food supply chain. Future developments to watch include whether the case counts in New Hampshire will surpass the 2019 record of 200 confirmed infections. Observers will also be monitoring if more states in the region report confirmed cases beyond the current figures seen in Connecticut and New Hampshire. Additionally, the specific nature of the precautions being taken by establishments like Rein’s Deli may provide further insight into how the outbreak is being managed.
