Abstract

Helminthiasis is a neglected public health challenge threatening North Koreans. However, there is no precise estimate on the burden of helminthiasis in the region. This study therefore reviewed existing literature with the aim of analyzing the current state of helminthiasis among North Koreans, as well as highlighting the difference in the prevalence of helminthiasis between North Korean residents and refugees. All published resources citing helminthiasis among North Koreans were screened through the PubMed and a Korean bibliographic database as of April 2019. Official papers reported by the government and international agencies, as well as reports and books published in North Korea, were reviewed. After removing duplicated government reports, a total of 37 records were screened, and four were determined to be included for review. The total number of study subjects was 621 from the four eligible studies. Forty percent of them were refugees living outside North Korea. Total positive rate of any kind of helminths was 37.7%. Ascaris was the most widespread helminths with a prevalence estimate of 41.1%. The total positive rate of helminthiasis among residents living in North Korea was significantly higher than that among North Korean refugees (47.2% vs. 23.4%, chi-square p-value \textless 0.001). Poor hygiene, malfunctioning public health infrastructure, and feculent agricultural practices accounted for the spread of helminthiasis. Appropriate strategies and policies should be developed to prevent and alleviate helminthiasis in North Korea.
