Cyclospora Outbreak Status: New Hampshire and National Trends
New Hampshire has confirmed two cases of cyclosporiasis in 2026, according to the state Department of Health and Human Services (DHHS). While 31 states have reported infections and 86 individuals have required hospitalization nationwide, health officials state that New Hampshire has not experienced an increase in cases compared to previous years. The illness, caused by a microscopic parasite, is typically contracted through the consumption of unwashed produce.
Understanding Cyclosporiasis Transmission and Symptoms
Cyclosporiasis is an intestinal infection caused by the microscopic, spherical parasite Cyclospora. According to the U.S. Centers for Disease Control and Prevention (CDC), the primary symptom is watery diarrhea. Patients often report “frequent and sometimes explosive bowel movements.”
Pro Tip: Prevention is Key
The most effective defense against Cyclospora is rigorous hygiene. The NH DHHS recommends thorough hand washing and the careful cleaning of all raw fruits and vegetables before preparation or consumption.
Comparing Local Data to National Outbreak Trends
While the national landscape involves 31 states and dozens of hospitalizations, New Hampshire’s current data remains within historical norms. The NH DHHS reports that over the last five years, the state typically identifies between 2 and 9 residents with the infection annually.
This contrast is important for public health monitoring. While other regions may be seeing elevated numbers, New Hampshire’s two confirmed cases for 2026 suggest a stable trend. The state agency maintains that it continues to monitor the broader, multi-state outbreak and remains prepared to scale its response if local infection rates begin to climb.
