This meta-analysis examined the prevalence of Cryptosporidium infection across humans, animals, and water sources in Korea. The overall pooled prevalence was found to be 7.1% (95% CI, 4.6-11.0%), with significant variations among different host groups. The study highlights the importance of ongoing surveillance to understand transmission dynamics and zoonotic risks associated with this pathogen.
Key findings
- The overall pooled prevalence of Cryptosporidium was 7.1% (95% CI, 4.6-11.0%).
- Prevalence in humans was higher in rural areas during the 1990s but has generally decreased in later studies.
- Cattle showed substantial prevalence, particularly in young calves, with significant variability.
- Cryptosporidium oocysts were detected in environmental water sources, linked to a waterborne outbreak in 2012.
Why it matters
Understanding the prevalence and distribution of Cryptosporidium is crucial for public health, as it is a significant waterborne pathogen that poses risks to both human and animal health. This knowledge can inform prevention strategies and surveillance efforts.
