Background Rabies continues to be a serious threat to global public health endangering people’s health and public health safety.In the People’s Republic of China,multi-sectoral and comprehensive prevention and control strategies have aimed to extensively curb human rabies transmission.Here,we examine the current state of rabies infection in China,explore strategic interventions put in place in response to WHO’s ambition of“Zero rabies deaths by 2030”and critically assess the constraints and feasibility of dog-mediated rabies elimination in China.Methods This study analyzed and evaluated the process towards dog-mediated rabies elimination in China from five perspectives:namely,human,dog,policy,challenge,and prospects.Evidence-based data on progress of dog-mediated rabies elimination in China was derived from a number of sources;a literature search was undertaken using PubMed,Web of Science and CNKI databases,distribution data for human rabies cases as derived from the Data-center of the China Public Health Science and policy and document data were obtained from official websites of the relevant China ministries and commissions.Results The incidence of human rabies cases in China have shown a downward trend year-on-year since 2007.Implementation of a government-led,multi-sectoral“One Health”approach to combating rabies has driven down the total number of rabies deaths nationwide to around 200 in 2020.The number of provincial-level administrative divisions(PLADs)reporting human cases of rabies has also decreased to 21 in 2020,13 of which reported less than 10 cases.Furthermore,the number of outpatient visits seeking rabies post-exposure prophylaxis has risen dramatically over the past two decades,with demand being 15 times higher than it was initially.There remain however,significant gaps in rabies elimination outcomes across the different regions of China.To date the target of achieving a canine rabies vaccination rate of>75%has not been met.The challenges of rabies immunization of dogs and dog management in underd

The World Health Organization(WHO)certified China as officially malaria-free on June 30,2021.Looking back at the public health history in China,malaria elimination has been a product of complex social engineering.Here,we summarized our experience and lessons,and found that malaria control and elimination in China is mainly attributed to governmental leadership,consistent efforts,technological innovations,and adaptive approaches.We also raised that vigilance should focus on imported cases through strengthening surveillance and response systems in order to prevent any re-establishment of transmission after elimination.China should continue to maintain its laboratory,clinical and field epidemiology capabilities.Continuous policy and financial support,multi-sectoral cooperation,and innovative strategies and approaches will remain essential.By integrating these,a malaria-free status can become sustainable.

Circulating tumor cells(CTCs)are recognized as the main source of tumor recurrence and metastasis.Eliminating the CTCs in peripheral blood provides a new strategy to reduce the probability of recurrence or metastasis.Here,we proposed a concept to eliminate CTCs by inserting a needle in the superficial blood vessel.Using the property of ZnO and the structure of nanoflowers,we designed a medical needle coated with ZnO nanoflowers(ZNFs),which killed about 90%of captured CTCs in vitro and prevented the injecting CTCs from spreading to lung tissue in BABL/c mouse model.Results in vitro and in vivo demonstrated that the CTCs not only were captured and killed,but also detached from the needle surface after dead,enabling the ZNFs needle continually eliminate CTCs.Furthermore,a theoretical model was presented to explain the penetration mechanism of cells by nanostructures,which indicated that nanoflowers structure can puncture CTCs more easily than vertical nanowire structure.The concept of inserting an intravascular needle provides a potential strategy to lower the concentration of CTCs in blood and reduce the probability of tumor recurrence or metastasis.

Compared with first-order surface-related multiples from marine data,the onshore internal multiples are weaker and are always combined with a hazy and occasionally strong interference pattern.It is usually difficult to discriminate these events from complex targets and highly scattering overburdens,especially when the primary energy from deep layers is weaker than that from shallow layers.The internal multiple elimination is even more challenging due to the fact that the velocity and energy difference between primary reflections and internal multiples is tiny.In this study,we propose an improved method which formulates the elimination of the internal multiples as an optimization problem and develops a convolution factor T.The generated internal multiples at all interfaces are obtained using the convolution factor T through iterative inversion of the initial multiple model.The predicted internal multiples are removed from seismic data through subtraction.Finally,several synthetic experiments are conducted to validate the effectiveness of our approach.The results of our study indicate that compared with the traditional virtual events method,the improved method simplifies the multiple prediction process in which internal multiples generated from each interface are built through iterative inversion,thus reducing the calculation cost,improving the accuracy,and enhancing the adaptability of field data.

China has accumulated multiple practices and experiences in building and enhancing malaria surveillance and response system. As China’s engagement into global health has gathered stronger momentum than ever, China together with the Swiss Tropical and Public Health Institute and WHO has organised five sessions of the International Forum on Surveillance-Response System Leading to Tropical Diseases elimination during 2012–2020, in which malaria elimination has always been one of the hottest topics. In this study, the roles of international network on the surveillance and response system were explored to achieve a global malaria-free goal. China’s approach to malaria elimination has demonstrated significance of global collaboration on taking joint prevention and control, and building a worldwide institutional-based network.

Background: Border malaria is one of the most intractable problems hindering malaria elimination worldwide.Movement of both the human population and anopheline mosquitoes infected with Plasmodium spp.can cause cross-border malaria transmission.The Yunnan border area was still hyperendemic for malaria in the early part of this century.The objective of this case study was to analyze the strategies,interventions and impacts of malaria control and elimination in the Yunnan border area.Main text: A total of 10,349 malaria cases and 17.1 per 10,000 person-years of annual parasite incidence(API)were reported in the border area in 2003.Based on natural village-based stratification,integrated interventions,including mass drug administration for radical cures and preventive treatment,clinically presumptive treatment of all febrile patients for malaria and indoor residual spraying or dipping bed nets with insecticides were successfully carried out from 2003 to 2013.The overall API was reduced to 0.6 per 10,000 person-years by 2013,while effective cross-border collaboration interventions dramatically reduced the malaria burden in the neighbouring border areas of Myanmar.From 2014 forward,the comprehensive strategy,including universal coverage of surveillance to detect malaria cases,a rapid response to possible malaria cases and effective border collaboration with neighbouring areas,successfully eliminated malaria and prevented reintroduction of malaria transmission in the Yunnan border area.Conclusions: In Yunnan malaria burden has successfully reduced by dynamically accurate stratification and comprehensive interventions;and then the region achieved elimination and prevented reintroduction of malaria transmission through intensive surveillance,rapid response and border collaboration.Other border areas should perform their own intervention trials to develop their own effective strategy.

Exactly 10 years ago,on 25 October 2012,a group of scientists,policy-makers,and practitioners undertook an ambitious project to launch a new open-access journal,named Infectious Diseases of Poverty[1].The idea had originated from a think-tank put forth by the Special Programme for Research and Training in Tropical Diseases(TDR),an organisation co-sponsored by the United Nations Children’s Fund(UNICEF),the United Nations Development Programme(UNDP),the World Bank,and the World Health Organization(WHO).Indeed,this think-tank published a comprehensive Global Report for Research on Infectious Diseases of Poverty[2]that guided the scope and remit of Infectious Diseases of Poverty.
