Rising Concerns Over Parasite Infections in Korea
The Korea Health Management Association, known as the Health Cooperative, has raised concerns about an increasing risk of parasite infections. While the number of reported cases has been steadily declining over the years, recent trends suggest a shift in how these infections are being contracted.
According to data from the Korea Centers for Disease Control and Prevention’s infectious disease portal, the number of parasitic infection reports dropped significantly from 3,296 in 2014 to 551 in 2024. However, this downward trend is not uniform across all types of parasites. The rise in international travel, changing dining habits, and the growing number of pets have led to more diverse and unusual cases of parasitic infections being reported in Korea.
Medical experts warn that individuals can be exposed to parasitic eggs while collecting wild vegetables or engaging in gardening activities. Additionally, consuming raw or undercooked freshwater fish, such as marsh snails or sweetfish commonly found in amusement parks, can also lead to infections.
A recent case involved a woman in her 60s who experienced symptoms like intermittent gastrointestinal discomfort, indigestion, constipation, and diarrhea. Despite normal blood and organ function test results, a colonoscopy revealed four adult parasites in her digestive tract. These parasites were identified as a rare species called pre-testine fluke through morphological and genetic analysis.
This discovery marks the first confirmed case of this particular parasite in Korea in over a decade. Notably, the parasite was found not only in the small intestine but also at the distal end of the small intestine and in the large intestine, which is different from the typical location of most flukes.
The study on this rare case was published in the journal Emerging Infectious Diseases (EID), a SCIE-level publication by the U.S. Centers for Disease Control and Prevention. This highlights the importance of ongoing research and awareness in the medical community.
The Health Cooperative plays a crucial role in addressing parasitic infections. As a specialized agency, it conducts research, prevention projects, and inspections related to parasitic diseases. With 17 branches nationwide, the organization provides accurate identification tests for parasites found during endoscopies and offers detailed results to patients.
These tests are essential for monitoring the presence of major parasites still prevalent in Korea, such as roundworms, whipworms, and other similar species. Medical institutions, including university hospitals and general hospitals, often request testing for suspected parasite samples, helping to improve diagnostic accuracy in challenging cases.
In addition to its clinical work, the Health Cooperative actively participates in national parasite investigation projects. Annual surveys of local residents help determine the prevalence of parasitic diseases, providing critical data for formulating infectious disease prevention policies.
The MediCheck Lab emphasizes that the cooperative’s parasite testing system is making a practical difference in the medical field. It supports the ability to diagnose parasites accurately in Korea and promotes public health education through initiatives like the Parasite Museum. This museum educates the general public and students about parasites, emphasizing the importance of hygiene and health through interactive exhibits.
