Hawaii health officials confirmed two additional cases of cyclosporiasis in state residents who contracted the intestinal illness while traveling outside the islands, bringing the total number of confirmed infections reported in the state this year to three, according to the state Department of Health.
Travel History and Infection Source
The two newest patients are members of the same household who traveled together internationally and to the mainland, an area that has reported a cyclosporiasis outbreak, according to health officials. Investigators determined the infections were acquired outside Hawaii based on the patients’ travel history, symptom onset, and the known incubation period of the parasite.
According to State Epidemiologist Dr. Sarah Kemble, the earlier confirmed case this year involved a nonresident visitor who also contracted the illness outside the islands. Health officials emphasized there is no evidence of locally acquired infection or ongoing community transmission within Hawaii.
Did you know? Cyclosporiasis is caused by Cyclospora cayetanensis, a microscopic parasite. Because the parasite must mature in the environment before it can infect humans, the illness does not spread directly from person to person, according to health authorities.
Symptoms and Medical Guidance
Symptoms of cyclosporiasis typically develop about one week after exposure, though they can appear anywhere from two days to two weeks later. The most frequent sign of infection is watery diarrhea. Patients may also experience a loss of appetite, weight loss, stomach cramps or bloating, nausea, increased gas, fatigue, and less commonly, vomiting or a low-grade fever.
“We encourage anyone experiencing persistent diarrhea after recent travel to seek medical care,” Dr. Kemble said in a statement. Without treatment, symptoms can persist for several weeks or longer and may follow a relapsing pattern of coming and going.
Prevention and Treatment Measures
Health officials advise residents to practice thorough handwashing before preparing or eating food, rinse fresh fruits and vegetables under running water, and follow safe food handling practices. Cyclosporiasis is treatable with prescription antibiotics.
Healthcare providers who suspect an infection are encouraged by the Department of Health to report cases and submit appropriate specimens for testing. State officials stated they will continue monitoring for additional cases and working with medical providers to detect any potential signs of local transmission.
Frequently Asked Questions
What is cyclosporiasis?
Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis, which is typically contracted by consuming food or water contaminated with the organism.
Can cyclosporiasis spread from person to person?
No. According to health officials, the parasite must mature in the environment before becoming infectious, meaning direct transmission between individuals does not occur.
Who is at risk in Hawaii?
The risk to the general public remains low because all confirmed cases this year involved individuals who were exposed while traveling outside the state.
