“…As shown in the results of this study, the majority of parasite positive cases were confirmed as T. trichiura infection. The high prevalence of trichuriasis in this study is in concordance with previous studies [ 4 , 5 ]. According to Lee et al [ 9 ], a refugee from NK diagnosed by colonoscopy was determined to have most probably been infected before leaving NK, as had been suffering the typical symptoms of intestinal helminthiasis while still living there.…”

“…Although some food-borne and zoonotic parasite infections along with malaria are still reported frequently, soil-transmitted parasites have been well controlled in South Korea [ 3 ]. Soil-transmitted helminthiases (STH), however, remain prevalent in some areas of North Korea (NK) and among North Korean refugees who manage to escape to the south [ 4 , 5 ]. Whereas a clear understanding of the health status of NK is mandatory for STH prevention and control measures, this objective is hampered by the lack of reliable data [ 6 ].…”

Infections of Soil-Transmitted Helminth in Refugees from North Korea

Soil-transmitted helminthiases (STH) are now no longer public health problems in the Republic of Korea (South Korea), but their status are unavailable in the residents of North Korea (NK) despite the expectation of large scale traffic and future reunification of the Korean Peninsula. A total of 20 female refugees from NK who had been admitted to the Division of Gastroenterology, Dankook University Hospital, were subjected in this study. Among them, 15 refugees were examined by the colonoscopy and 10 ones were examined with the stool examination (formalin-ether sedimentation). Both diagnostic methods were commonly adopted in 5 patients. Eggs of Trichuris trichiura were detected in 7 out of 10 refugees in the stool examination. In the colonoscopy, T. trichiura worms were found in 6 (40.0%) out of 15 refugees. Total 9 (45.0%) peoples were confirmed to be infected with human whipworms. Additionally, 1 case of clonorchiasis was diagnosed in the stool examination and a worm of Ascaris lumbricoides was discovered from a trichuriasis case. These findings suggested that STH is highly prevalent in NO, in which living conditions are not so good in the aspect of general hygiene and medical care.

Porcine cysticercosis (Taenia solium and Taenia asiatica): mapping occurrence and areas potentially at risk in East and Southeast Asia

et al. 2018

BackgroundDue to the relative short life span and the limited spatial movement, porcine cysticercosis is an excellent indicator of current local active transmission. The aim of this study was to map at province-level, the occurrence of T. solium and T. asiatica in pigs and areas at risk of transmission to pigs in East and Southeast Asia, based on the density of extensive pig production systems and confirmed reports of porcine cysticercosis.MethodsThis study covered East and Southeast Asia, which consist of the following countries: Brunei, Cambodia, China, East Timor, Indonesia, Japan, Laos, Malaysia, Mongolia, Myanmar, North Korea, Philippines, Singapore, South Korea, Thailand and Vietnam. Literature searches were carried out to identify current epidemiological data on the occurrence of porcine cysticercosis caused by T. solium and T. asiatica infections. Modelled densities of pigs in extensive production systems were mapped and compared to available data on porcine cysticercosis.ResultsPorcine cysticercosis was confirmed to be present during the period 2000 to 2018 in eight out of the 16 countries included in this study. Taenia solium porcine cysticercosis was confirmed from all eight countries, whereas only one country (Laos) could confirm the presence of T. asiatica porcine cysticercosis. Province-level occurrence was identified in five countries (Cambodia, Indonesia, Laos, Myanmar, and Vietnam) across 19 provinces. Smallholder pig keeping is believed to be widely distributed throughout the region, with greater densities predicted to occur in areas of China, Myanmar, Philippines and Vietnam.ConclusionsThe discrepancies between countries reporting taeniosis and the occurrence of porcine cysticercosis, both for T. solium and T. asiatica, suggests that both parasites are underreported. More epidemiological surveys are needed to determine the societal burden of both parasites. This study highlights a straightforward approach to determine areas at risk of porcine cysticercosis in the absence of prevalence data.Electronic supplementary materialThe online version of this article (10.1186/s13071-018-3203-z) contains supplementary material, which is available to authorized users.

The global epidemiology of clonorchiasis and its relation with cholangiocarcinoma

et al. 2012

This paper reviews the epidemiological status and characteristics of clonorchiasis at global level and the etiological relationship between Clonorchis sinensis infection and cholangiocarcinoma (CCA). A conservative estimation was made that 15 million people were infected in the world in 2004, of which over 85% distributed in China. The epidemiology of clonorchiasis is characterized by rising trend in its prevalence, variability among sexes and age, as well as endemicity in different regions. More data indicate that C. sinensis infection is carcinogenic to human, and it is predicted that nearly 5 000 CCA cases attributed to C. sinensis infection may occur annually in the world decades later, with its overall odds ratio of 4.47. Clonorchiasis is becoming one major public health problem in east Asia, and it is worthwhile to carry out further epidemiological studies.
