1Elimination of tropical disease through surveillance and response显示文摘Surveillance and response represent the final crucial steps in achieving effective control and particularly elimination of communicable diseases as recognized in the area of neglected tropical diseases(NTDs),applied in increasing numbers in endemic countries with ongoing control and elimination programmers.More and more national NTD elimination initiatives are scheduled based on the innovative and effective One world-One health perspective to detect pockets of transmission and disease reintroduction.Resource-constrained countries,which carry the heaviest NTD burdens,face various challenges how to strengthen the health system as well as developing effective and novel tools for sureillance and response tailored to local settings.Surillance-response approaches take place in two different stages oralling the basic components of the sureillance response system for NTD elimination.Six different research priorities have been identified:(1)dynamic mapping of transmission,(2)near real-time capture of population dynamics,(3)modelling based on a minimum essential database/dataset,(4)implementation of mobile health(m-health)and sensitive diagnostics,(5)design of effective response packages tailored to different transmission settings and levels,and( 6)validation of approaches and responses packages.Xiao-Nong Zhou RobertBergquist Marcel Tanner 2013Infectious Diseases of Poverty2013,2,1:27

3Surveillance-response systems: the key to elimination of tropical diseases显示文摘Tropical diseases remain a major cause of morbidity and mortality in developing countries.Although combined health efforts brought about significant improvements over the past 20 years,communities in resource-constrained settings lack the means of strengthening their environment in directions that would provide less favourable conditions for pathogens.Still,the impact of infectious diseases is declining worldwide along with progress made regarding responses to basic health problems and improving health services delivery to the most vulnerable populations.The London Declaration on Neglected Tropical Diseases(NTDs),initiated by the World Health Organization’s NTD roadmap,set out the path towards control and eventual elimination of several tropical diseases by 2020,providing an impetus for local and regional disease elimination programmes.Tropical diseases are often patchy and erratic,and there are differing priorities in resources-limited and endemic countries at various levels of their public health systems.In order to identify and prioritize strategic research on elimination of tropical diseases,the‘First Forum on Surveillance-Response System Leading to Tropical Diseases Elimination’was convened in Shanghai in June 2012.Current strategies and the NTD roadmap were reviewed,followed by discussions on how to identify and critically examine prevailing challenges and opportunities,including inter-sectoral collaboration and approaches for elimination of several infectious,tropical diseases.A priority research agenda within a‘One Health-One World’frame of global health was developed,including(i)the establishment of a platform for resource-sharing and effective surveillance-response systems for Asia Pacific and Africa with an initial focus on elimination of lymphatic filariasis,malaria and schistosomiasis;(ii)development of new strategies,tools and approaches,such as improved diagnostics and antimalarial therapies;(iii)rigorous validation of surveillance-response systems;and(iv)designing pilot studies to transfer Chinese experiences of successful surveillance-response systems to endemic countries with limited resources.Ernest Tambo Lin Ai Xia Zhou Jun-Hu Chen Wei Hu Robert Bergquist Jia-Gang Guo Jürg Utzinger Marcel Tanner Xiao-Nong Zhou 2014Infectious Diseases of Poverty2014,3,1:14
4Surveillance and response systems for elimination of tropical diseases: summary of a thematic series in Infectious Diseases of Poverty显示文摘The peer-reviewed journal Infectious Diseases of Poverty provides a new platform to engage with,and disseminate in an open-access format,science outside traditional disciplinary boundaries.The current piece reviews a thematic series on surveillance-response systems for elimination of tropical diseases.Overall,22 contributions covering a broad array of diseases are featured–i.e.clonorchiasis,dengue,hepatitis,human immunodeficiency virus/acquired immune deficiency syndrome(HIV/AIDS),H7N9 avian influenza,lymphatic filariasis,malaria,Middle East respiratory syndrome(MERS),rabies,schistosomiasis and tuberculosis(TB).There are five scoping reviews,a commentary,a letter to the editor,an opinion piece and an editorial pertaining to the theme“Elimination of tropical disease through surveillance and response”.The remaining 13 articles are original contributions mainly covering(i)drug resistance;(ii)innovation and validation in the field of mathematical modelling;(iii)elimination of infectious diseases;and(iv)social media reports on disease outbreak notifications released by national health authorities.Analysis of the authors’affiliations reveals that scientists from the People’s Republic of China(P.R.China)are prominently represented.Possible explanations include the fact that the 2012 and 2014 international conferences pertaining to surveillance-response mechanisms were both hosted by the National Institute of Parasitic Diseases(NIPD)in Shanghai,coupled with P.R.China’s growing importance with regard to the control of infectious diseases.Within 4 to 22 months of publication,three of the 22 contributions were viewed more than 10000 times each.With sustained efforts focusing on relevant and strategic information towards control and elimination of infectious diseases,Infectious Diseases of Poverty has become a leading journal in the field of surveillance and response systems in infectious diseases and beyond.Xia Zhou Peiling Yap Marcel Tanner Robert Bergquist Jürg Utzinger Xiao-Nong Zhou 2016Infectious Diseases of Poverty2016,5,1:12
