In 2010, China issued the National Malaria Elimination Action Plan (2010-2020), with the goal of eliminating malaria nationwide by 2020 (1). Malaria cases in China subsequently decreased dramatically, and no [...]

To the Editor: Imported malaria has become a major public health challenge in China. Despite an 89.8% decrease in total cases from 2008 (26,873) through 2012 (2,729), the proportion of [...]

Malaria cases have dramatically declined in China along the Myanmar border, attributed mainly to adoption of the 1-3-7 surveillance and response approach. No indigenous cases have been reported in China since 2017. Counties in the middle and southern part of the border area have a higher risk for malaria importation and reestablishment after elimination. [ABSTRACT FROM AUTHOR]

Objective To analyze malaria epidemiological characteristics in China, 2010-2019, so as to provide evidence-based proof for target interventions on malaria elimination. Methods The data of web-based Infectious Disease Information Reporting Management System (IDIRMS) and Parasitic Diseases Information Reporting Management System (PDIRMS) from 2010 to 2019 were collected and analyzed. Results During 2010-2019, imported malaria cases were reported in all provinces, and in total 29 248 reported cases(2 925 cases annually), including 767 clinically diagnosed cases (2.62%), 7 388 Plasmodium vivax cases (25.26%), 18 032 P. falciparum cases (61.65%), 524 P. malariae cases (1.79%), 2 049 P. ovale cases (7.01%), 370 mixed-infection (1.27%), 2 P. knowlesi (0.01%), and 116 unclassified cases (0.40%). The imported malaria cases were mainly from Myanmar ( 2 750 cases, 9.40%), Ghana ( 2 606, 8.91%) and Nigeria ( 2 127, 7.27%); and most of them were reported in Yunnan ( 5 794, 19.81%), Guangxi ( 3 130, 10.70%) and Jiangsu (2 917, 9.97%). The temporal distribution was concentrated in June (4 141, 14.16%). Most cases (27 454, 93.87%) were found in male. A total of 181 deaths resulting from P. falciparum were reported. No obvious difference was found among interval from onset to diagnosis during the same timeframe (P>0.05). From 2013 to 2019, the imported cases were mainly diagnosed (8 680, 39.75%) and reported (8 783, 40.22%) at county level. The proportion of diagnosis and report at county level exhibit an decreasing trend, while the municipal level was seen with a increasing trend. From 2013 to 2019, the imported cases were diagnosed (15 730, 72.03%) and reported (16 536, 75.72%) by medical institutions. The proportion of diagnosis and report by medical institutions exhibit an increasing trend, while the CDC institutions were observed with a decreasing trend. Conclusion To prevent the reestablishment caused by imported malaria, it is necessary to continue to strengthen inter-sectoral collaboration and surveillance, to carry out timely detection and appropriately treatment of imported cases, carefully investigate and assess the transmission risk of imported cases, and timely response to the risk foci or population. Furthermore, it is essential to conduct "strengthen inter-sectoral collaboration, timely case detection, promptly foci response"to effectively blocking the risk of reestablishment, and consolidating the achievements of malaria elimination.

Although the past decades have seen a remarkable decrease in malaria-caused mortality and morbidity, the infection remains a significant challenge to global health. In the battle against malaria, China has gained notable feat and achievement since the 1940s through the efforts of several generations. Notably, China has not recorded a single indigenous malaria case since August 2016. The National Institute of Parasitic Diseases of the Chinese Center for Disease Control and Prevention (NIPD), as the only specialized institution for parasitic disease at the national level, has played a significant role in the malaria control, prevention, and elimination in China in the different historical periods. In order to transfer Chinese experiences on malaria control and elimination to other Low and Middle Income Countries (LMICs) and to improve global health collaboration, we have summarized and reviewed the contributions and achievements by the NIPD over the past 70 years, covering the epidemic situation; field investigation and laboratory experimental research on both parasite and vector; research and development on diagnostics, drugs, and insecticides; surveillance and response; technical and international. Support and cooperation. In addition, we also focus in particular on malaria retransmission risk, strategies on management of imported malaria cases and mobile populations, surveillance and response capacity to be maintained in post-elimination stage, challenges on diagnosis, drug resistance, and insecticide resistance as future concerns.

China has achieved a great success in control and elimination of key parasitic diseases. In 2007, the elimination of lymphatic filariasis was verified by WHO. The schistosomiasis incidence and snail-distributed areas have reduced to the lowest level in the history. The transmission and disease burden of echinococcosis have been contained largely, and the populations infected with soil-transmitted trematode and food-borne parasites have also shown a significantly declining trend. Because of rapid globalization and climate changes, however, many new challenges have arisen. In his paper, the 2020-2030 roadmaps towards the control and elimination of these key parasitic diseases are described. Moreover, China is actively implementing its global health strategy, and will be more and more engaged into global health affairs, in which a series of China-Africa health cooperation projects have been in planning with a wish of making a greater contribution to the SDGs.
