BackgroundMalaria was once one of the most serious public health problems in China. However, the disease burden has sharply declined and epidemic areas have shrunk after the implementation of an integrated malaria control and elimination strategy, especially since 2000. In this review, the lessons were distilled from the Chinese national malaria elimination programme and further efforts to mitigate the challenges of malaria resurgence are being discussed.MethodsA retrospective evaluation was performed to assess the changes in malaria epidemic patterns from 1950 to 2017 at national level. The malaria data before 2004 were collected from paper-based annual reports. After 2004, each of the different cases from the Infectious Diseases Information Reporting Management System (IDIRMS) was closely examined and scrutinized. An additional documenting system, the National Information Management System for Malaria, established in 2012 to document the interventions of three parasitic diseases, was also examined to complete the missing data from IDIRMS.ResultsFrom 1950 to 2017, the occurrence of indigenous malaria has been steeply reduced, and malaria-epidemic regions have substantially shrunk, especially after the launch of the national malaria elimination programme. There were approximately 30 million malaria cases annually before 1949 with a mortality rate of 1%. A total of 5999 indigenous cases were documented from 2010 to 2016, with a drastic reduction of 99% over the 6 years (2010, n = 4262; 2016, n = 3). There were indigenous cases reported in 303 counties from 18 provinces in 2010, but only 3 indigenous cases were reported in 2 provinces nationwide in 2016. While in 2017, for the first time, zero indigenous case was reported in China, and only 7 of imported cases were in individuals who died of Plasmodium falciparum infection.ConclusionMalaria elimination in China is a country-led and country-owned endeavour. The country-own efforts were a clear national elimination strategy, supported by two systems, namely a case-based surveillance and response system and reference laboratory system. The country-led efforts were regional and inter-sectoral collaboration as well as sustained monitoring and evaluation. However, there are still some challenges, such as the maintenance of non-transmission status, the implementation of a qualified verification and assessment system, and the management of imported cases in border areas, through regional cooperation. The findings from this review can probably help improving malaria surveillance systems in China, but also in other elimination countries.Electronic supplementary materialThe online version of this article (10.1186/s12936-018-2444-9) contains supplementary material, which is available to authorized users.

Abstract. This study aims to explore and characterize the malaria-endemic situation and trends from 2004 to 2013, to provide useful evidence for subsequently more effective strategic planning of malaria elimination in China. A total of 256,179 confirmed malaria cases were recorded in this period, and 86.8% of them were reported during 2004-2008 . Between 2004, Plasmodium vivax was the major species (72.2%) of malaria parasite. Most cases (67.3%) were found in male, and mainly in the age group of 35-39 years. A total of 236 deaths resulting from malaria were reported and nearly half (45.3%) of them were in Yunnan province. In all, 204,760 local malaria (79.9%) and 51,419 imported malaria (20.1%) were observed during 2004-2013. However, afterward the proportion of imported malaria continuously increased from 2004 (16.2%) to 2013 (97.9%). Moreover, 9,285 imported malaria cases were recorded during 2011-2013 in China, of which 5,976 cases (64.4%) came back from Africa. Overall, China has made achievements in controlling malaria, the locally transmitted malaria significantly declined in the past decades, by which the incidence has achieved historically the lowest levels. On the other hand, imported malaria has increasingly become a severe threat to malaria elimination. Therefore, to prevent the reintroduction of malaria, surveillance systems need to be well planned and managed to ensure timely case detection and prompt response at the elimination stage.

Abstract. The surveillance and response system remains one of the biggest challenges to malaria elimination along the China-Myanmar border. In China, "1-3-7" approach was developed to guide elimination activities according to the National Malaria Elimination Program, which is a simplified set of targets that delineates responsibilities and actions. The time frame of the approach has been incorporated into the nationwide web-based disease reporting system: 1, case reporting within 1 day after diagnosis; 3, case investigation within 3 days; and 7, focus investigation and action within 7 days. Herein, the data on malaria cases in 2005-2014 and after the "1-3-7" implementation in 2013-2014 of the 18 counties at the China-Myanmar border are reviewed and analyzed. Results showed that the total cases decreased while the proportion of imported cases rose. The "1-3-7" was well executed, except for the "3" indicator, which was 96.3% accomplished on average in the 18 border counties, but needs to be further strengthened. More efforts are highlighted for timely and accurate case detection as well as proactive mapping of disease transmission hot spots to facilitate the elimination of border malaria.

BackgroundTowards the implementation of national malaria elimination programme in China since 2010, the epidemiology of malaria has changed dramatically, and the lowest malaria burden was achieved yearly. It is time to analyze the changes of malaria situation based on surveillance data from 2010 to 2012 to reconsider the strategies for malaria elimination.Methods and Principal findingsMalaria epidemiological data was extracted from the provincial annual reports in China between 2010 and 2012. The trends of the general, autochthonous and imported malaria were analyzed, and epidemic areas were reclassified according to Action Plan of China Malaria Elimination (2010-2020). As a result, there reported 2743 malaria cases with a continued decline in 2012, and around 7% autochthonous malaria cases accounted. Three hundred and fifty-three individual counties from 19 provincial regions had autochthonous malaria between 2010 and 2012, and only one county was reclassified into Type I (local infections detected in 3 consecutive years and the annual incidences ≥ 1/10,000) again. However, the imported malaria cases reported of each year were widespread, and 598 counties in 29 provinces were suffered in 2012.Conclusions/SignificanceMalaria was reduced significantly from 2010 to 2012 in China, and malaria importation became an increasing challenge. It is necessary to adjust or update the interventions for subsequent malaria elimination planning and resource allocation.

ObjectiveSince the Guangxi government implemented public county hospital reform in 2009, there have been no studies of county hospitals in this underdeveloped area of China. This study aimed to establish an evaluation indicator system for Guangxi county hospitals and to generate recommendations for hospital development and policymaking.MethodsA performance evaluation indicator system was developed based on balanced scorecard theory. Opinions were elicited from 25 experts from administrative units, universities and hospitals and the Delphi method was used to modify the performance indicators. The indicator system and the Topsis method were used to evaluate the performance of five county hospitals randomly selected from the same batch of 2015 Guangxi reform pilots.ResultsThere were 4 first-level indicators, 9 second-level indicators and 36 third-level indicators in the final performance evaluation indicator system that showed good consistency, validity and reliability. The performance rank of the hospitals was B > E > A > C > D.ConclusionsThe performance evaluation indicator system established using the balanced scorecard is practical and scientific. Analysis of the results based on this indicator system identified several factors affecting hospital performance, such as resource utilisation efficiency, medical service price, personnel structure and doctor–patient relationships.
