“…Based on the statistics, cattle farmers in Mlaten village already have good sanitation hygiene so no relationship was found between environmental sanitation and the incidence of intestinal worm infection. The finding of this research is in agreement with a study conducted in Palu City [13] and research on the incidence of ascariasis and trichuriasis in Padang City [14] which showed that there was no significant relationship between environmental sanitation and soil-transmitted helminth infections. Research conducted in Minahasa Regency [15] used three sanitation indicators.…”

Background: Soil-transmitted helminth infections are diseases caused by the ingestion of infective stages (in the form of eggs, larvae, cysticercoid, and plerocercoid) of worms (nematodes, cestodes, and trematodes) into the human gastrointestinal tract through the fecal-oral route. The risk factors associated with soil-transmitted helminth infections are environmental factors and hygiene factors. These factors are commonly found in agricultural areas. Therefore, we conducted research in Mlaten Village because the majority of the villagers work as cattle breeders. In addition, the surrounding community, especially cattle breeders, experienced excessive diarrhea that was probably caused by a lack of hygiene knowledge, poor sanitation, and low awareness of cattle care and management. This study aims to determine the prevalence and risk factors of soil-transmitted helminth infections in cattle farmers in Mlaten village, Mojokerto, East Java. Methods: This research was conducted using a survey method and cross-sectional study design with 30 cattle farmers as respondents. Human and cow feces were identified using a staining method in the form of 2% eosin. We also used questionnaires to determine the risk factors. The data obtained were presented descriptively and risk factors were analyzed using the chi-square test. Results: The results showed that the habit of cutting nails (OR= 0.083; CI 95%= 0.007-0.950; p<0.05), the habit of washing hands (OR= 0.000; CI 95%= 0.000-0.000; p<0.05), and the habit of washing hands with soap (OR= 0.040; CI 95%= 0.267-18.925; p<0.05) have a significant effect on the incidence of soil-transmitted helminth infections. Conclusion: The prevalence of soil-transmitted helminth infections is significant to personal hygiene risk factors.

“…Nowadays, infections with these helminths are sporadically reported, including presumably imported cases [128] and a case of multiple infections with Ascaris lumbricoides, Trichuris trichiura, and Necator americanus in an 84-year-old woman [132]. A clinical testing facility continues to detect a few ascariasis cases between 2000 and 2018 [133], but it is unknown whether these cases indicate recent Ascaris transmission. In the late 2010s, a schoolbased study detected no infection in five prefectures, suggesting that transmission has become rare even in the areas where high prevalence was previously reported [278], but it is not clear whether transmission of A. lumbricoides, Ancylostoma duodenal, N. americanus, and T. trichiura is eliminated in Japan.…”

Little attention has been paid to neglected tropical diseases (NTDs) in high-income countries and no literature provides an overview of NTDs in Japan. This scoping review aims to synthesize the latest evidence and information to understand epidemiology of and public health response to NTDs in Japan. Using three academic databases, we retrieved articles that mentioned NTDs in Japan, written in English or Japanese, and published between 2010 and 2020. Websites of key public health institutions and medical societies were also explored. From these sources of information, we extracted data that were relevant to answering our research questions. Our findings revealed the transmission of alveolar echinococcosis, Buruli ulcer, Chagas disease, dengue, foodborne trematodiases, mycetoma, scabies, and soil-transmitted helminthiasis as well as occurrence of snakebites within Japan. Other NTDs, such as chikungunya, cystic echinococcosis, cysticercosis, leishmaniasis, leprosy, lymphatic filariasis, rabies, and schistosomiasis, have been imported into the country. Government agencies tend to organize surveillance and control programs only for the NTDs targeted by the Infectious Disease Control Law, namely, echinococcosis, rabies, dengue, and chikungunya. At least one laboratory offers diagnostic testing for each NTD except for dracunculiasis, human African trypanosomiasis, onchocerciasis, and yaws. No medicine is approved for treatment of Chagas disease and fascioliasis and only off-label use drugs are available for cysticercosis, opisthorchiasis, human African trypanosomiasis, onchocerciasis, schistosomiasis, and yaws. Based on these findings, we developed disease-specific recommendations. In addition, three policy issues are discussed, such as lack of legal frameworks to organize responses to some NTDs, overreliance on researchers to procure some NTD products, and unaffordability of unapproved NTD medicines. Japan should recognize the presence of NTDs within the country and need to address them as a national effort. The implications of our findings extend beyond Japan, emphasizing the need to study, recognize, and address NTDs even in high-income countries.
