The current status of neglected tropical diseases in Japan: A scoping review.

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.

Current status of neglected tropical diseases (NTDs) in the Philippines.

In the Philippines, ten NTDs are prevalent, but only six namely LF, schistosomiasis, STH, food-borne trematodiases, rabies and leprosy are considered to be of public health importance. The 81 provinces in the country are endemic for at least one of these NTDs. Others may be endemic for two or even more of these diseases. Since 2000, after the Philippines accepted and implemented the WHO guidelines for NTDs prevention, control and elimination, significant progress has been achieved in reducing the magnitude of NTDs endemic in the country. Since 2009, out of 46 filariasis-endemic provinces, the number of provinces that has eliminated LF has progressively increased so that by 2015, 76% are already LF-free. By 2019, only four provinces remain endemic for LF. For schistosomiasis, as of 2012, report from the Department of Health (DOH) put the number of high endemic provinces at 10, moderately endemic at 6 and low to elimination levels at 12. For STH, results of the National Parasite Survey in the Philippines among school-aged children conducted in 2015 by the Research Institute for Tropical Medicine, the research arm of the Philippine DOH, however, showed that the overall cumulative prevalence was 28.4% with a prevalence range between 7.1% and 67.4%. The figures are way above the <20% prevalence standard set by the World Health Organization. Control and prevention efforts for FBTs just gained traction with the call of WHO for elimination of NTDs in 2015. There is an urgent need to update information by an intensive national baseline survey that can validate previous data as well as generate new information on the magnitude of the FBT problem in the Philippines. For leprosy, elimination activities have been intensified in high prevalence areas and from 2009 to 2013, case detection and prevalence were sustained at <1.0 per 10,000 population. Rabies elimination activities have been effective that by 2011, only five regions out of 16 remained with the highest number of rabies cases. In a period of seven years from 2010 to 2017, the number of rabies-free provinces and municipalities increased from 3 to 49. Problems continue to hound the NTD programmes in the Philippines as priorities shift to more urgent health problems in a country that is weighed down not only by the triple burden of disease but serious health consequences of emergencies and disasters and the fast-growing population itself. Paradigm shifts are suggested to replace the traditional and conventional perspectives of control. These include change from disease approach to intervention approach to allow for integration of strategies targeting several NTDs and multisectoral, multidisciplinary approach requiring strong, viable and sustainable partnerships involving various agencies of the government, public and private sector, pharmaceuticals, academe, researchers, local government units and the endemic communities themselves.

The burden of neglected tropical diseases in Ethiopia, and opportunities for integrated control and elimination.

BACKGROUND: Neglected tropical diseases (NTDs) are a group of chronic parasitic diseases and related conditions that are the most common diseases among the 2·7 billion people globally living on less than US$2 per day. In response to the growing challenge of NTDs, Ethiopia is preparing to launch a NTD Master Plan. The purpose of this review is to underscore the burden of NTDs in Ethiopia, highlight the state of current interventions, and suggest ways forward. RESULTS: This review indicates that NTDs are significant public health problems in Ethiopia. From the analysis reported here, Ethiopia stands out for having the largest number of NTD cases following Nigeria and the Democratic Republic of Congo. Ethiopia is estimated to have the highest burden of trachoma, podoconiosis and cutaneous leishmaniasis in sub-Saharan Africa (SSA), the second highest burden in terms of ascariasis, leprosy and visceral leishmaniasis, and the third highest burden of hookworm. Infections such as schistosomiasis, trichuriasis, lymphatic filariasis and rabies are also common. A third of Ethiopians are infected with ascariasis, one quarter is infected with trichuriasis and one in eight Ethiopians lives with hookworm or is infected with trachoma. However, despite these high burdens of infection, the control of most NTDs in Ethiopia is in its infancy. In terms of NTD control achievements, Ethiopia reached the leprosy elimination target of 1 case/10,000 population in 1999. No cases of human African trypanosomiasis have been reported since 1984. Guinea worm eradication is in its final phase. The Onchocerciasis Control Program has been making steady progress since 2001. A national blindness survey was conducted in 2006 and the trachoma program has kicked off in some regions. Lymphatic Filariasis, podoconiosis and rabies mapping are underway. CONCLUSION: Ethiopia bears a significant burden of NTDs compared to other SSA countries. To achieve success in integrated control of NTDs, integrated mapping, rapid scale up of interventions and operational research into co implementation of intervention packages will be crucial.

International task force for disease eradication

The eradication of smallpox from the world in 1977 proved the feasibility of infectious disease eradication. The International Task Force for Disease Eradication (ITFDE) is assessing the potential for global eradication of other infectious diseases. This report summarizes the ITFDE's findings on the potential to eradicate eight diseases based on draft versions of criteria under development (AU)
