Public health officials in North Carolina are investigating an outbreak of intestinal parasites that has affected 135 cases in Wake County since the beginning of May. Approximately 22 of these cases have been linked to three local restaurants, but inspections of these establishments were inconclusive. The parasite responsible for the outbreak is Cyclospora cayetanensis, which is transmitted through contaminated food and water. Symptoms of the illness, known as cyclosporiasis, include watery diarrhea, fever, fatigue, and aches and pains. While most cases resolve on their own, severe infections may require antibiotics and IV hydration. The CDC reports that cases of cyclosporiasis have been increasing in recent years in the U.S., with outbreaks also occurring in other states this summer.
The parasite Cyclospora is primarily transmitted through the feces of infected individuals, particularly via contaminated food and water. Symptoms of cyclosporiasis typically appear about a week after exposure and can last for several days to over a month. While most people infected with the parasite do not develop symptoms, those who do may experience severe discomfort, especially young children, older adults, and individuals with compromised immune systems. Treatment involves antibiotics and antidiarrheal medications, with IV hydration necessary in severe cases. Outbreaks of cyclosporiasis are more common in tropical or subtropical regions, but cases have also been reported in the U.S., often associated with fresh produce.
Health officials recommend washing hands regularly with soap and water, especially before eating or preparing food, and after using the bathroom, coughing, or sneezing. If soap and water are not available, an alcohol-based hand gel with at least 60 percent alcohol can be used. Following food safety recommendations for safe preparation and storage can also help minimize the risk of contracting cyclosporiasis. Individuals experiencing symptoms of Cyclospora infection are advised to seek medical attention from a healthcare provider. The CDC suggests that the increase in reported cases of cyclosporiasis in recent years may be partly due to the availability of more diagnostic tests.
Cases of cyclosporiasis have been on the rise in the U.S., with 537 reported cases in 2016 escalating to 4,703 in 2019. While most cases do not require medical treatment and resolve on their own, severe infections may necessitate antibiotic therapy and IV hydration. Health officials urge individuals to practice good hygiene by washing hands regularly and following safe food preparation practices to reduce the risk of contracting cyclosporiasis. If symptoms of infection are present, seeking medical attention from a healthcare provider is recommended to receive proper treatment and care. Outbreaks of cyclosporiasis have been reported in various states in the U.S., with fresh produce often being implicated as a potential source of transmission.
