Objective To establish a monitoring and evaluation indicator framework in the context of malaria elimination in pilot areas in China,so as to further assess the malaria elimination work in the future. Methods Based on the consultancy, and according to the government documents such as Action Plan for Malaria Elimination in China (2010-2020),Technical Guidance for Malaria Elimination,Programme Evaluation on Malaria Elimination,the indicators were set up at both provincial and county levels and their application was conducted in Yunnan and Anhui provinces to assess the accountability,accessibility and applicability. Results An indicator framework was built up including four key components,which were input,process, output and impact indicators,in which 95 were provincial indicators and 98 were county indicators. The completion rate of the indicators of Yunnan and Anhui provinces were 94.7%(90/95)and 95.8%(91/95)respectively;and the completion rate of in?dicators of Tengchong and Feidong counties were 93.9%(92/98)and 92.9%(91/98)respectively. Conclusion The estab?lished indicator framework is reliable and applicable,which could effectively help to track the malaria elimination progress and identify gaps.

Objective:To learn about the status quo and hotspots in the field of health policy research under the concept of One Health.Methods:The Web of Science Core Collection (WoS) database and China National Knowledge Infrastructure (CNKI) database from 2001 to 2020 were searched for publications in the field of health policy research under the concept of One Health. A total of 3 515 publications in English and 42 in Chinese were included, CiteSpace 5.6.R3 software was used to analyze the number of publications, countries, institutions, authors, and keywords, and to draw visual maps.Results:The number of publications in WoS database was 52 in 2001 and 500 in 2020, with an overall upward trend in the number of publications; the first relevant publication in CNKI database was published in 2009, and the number of publications increased to 13 by 2020, but the total number was still low (42). Among the countries, the USA had the highest number of publications (1 385), total citations (48 780) and highly cited (≥10 citations) publications (671). Switzerland had the highest citations per publication (89.72). China ranked 5th in the number of publications (160) and 8th in total citations (4 643) and citations per publication (29.02), with fewer highly cited publications (82). The English author partnership had a large collaborative team led by Chris Degeling at the University of Sydney; the Chinese author partnership had a large research team led by Lu Jiahai at the School of Public Health, Sun Yat-sen University. In terms of country cooperation, French node had the largest centrality (0.30), the centrality of Chinese nodes was 0.01. Emerging infectious diseases, zoonose, and antibiotic resistance were high-frequency keywords in the English publications, while COVID-19, zoonose, antibiotic resistance, and food safety were high-frequency keywords in the Chinese publications.Conclusions:From 2001 to 2020, the overall trend of the number of publications in health policy research under the concept of One Health worldwide is on the rise. Emerging infectious diseases, zoonose, antibiotic resistance, and food safety are the current research hotspots in this field.

Objective To investigate the epidemiological characteristics and diagnosis of imported Plasmodium malariae and P. ovale malaria cases in Anhui Province, Hubei Province, Zhejiang Province, Guangxi Zhuang Autonomous Region and Henan Province from 2014 to 2021, so as to provide insights into malaria control in these five provinces. Methods All data pertaining to malaria cases reported in five provinces of China were captured from Chinese Disease Control and Prevention Information System from 2014 to 2021, and the epidemiological characteristics of imported P. malariae and P. ovale malaria cases were analysed using a descriptive epidemiological method. The duration from onset of malaria to initial diagnosis, duration from initial diagnosis to definitive diagnosis, institutions of initial and definitive diagnoses, and proportion of correct malaria diagnosis at initial diagnosis were statistically analyzed. Results A total of 1 223 imported P. malariae and P. ovale malaria cases were reported in Anhui Province, Hubei Province, Zhejiang Province, Henan Province and Guangxi Zhuang Autonomous Region from 2014 to 2021, there were 158 P. malariae malaria cases (12.92%) and 1 065 P. ovale malaria cases (87.08%). Totally 98.53% (1 205/1 223) of the imported malaria cases were from Africa, with Angola (18.99%, 30/158), Nigeria (11.39%,18/158), Cameroon (10.76%, 17/158), Ghana (10.13%, 16/158) and the Democratic Republic of the Congo (10.13%,16/158) as predominant countries where P. malariae malaria cases were from, and Ghana (23.19%, 247/1 065), Cameroon (14.74%, 157/1 065), Nigeria (9.39%, 100/1 065) and Angola (6.95%, 74/1 065) as predominant countries where P. ovale malaria cases were from. There were significant differences in the duration from onset of malaria to initial diagnosis (χ² = 27.673, P = 0.000) and duration from initial diagnosis to definitive diagnosis of P. malariae and P. ovale malaria cases (χ² = 29.808, P = 0.000), and the proportions of correct initial diagnosis of P. malariae and P. ovale malaria cases were 38.61% (61/158) and 56.53% (602/1 065). There were 74.69% (118/158) of P. malariae malaria cases with definitive diagnosis in county-, city-, and province-level medical institutions, and 79.25% (844/1 065) of P. ovale malaria cases with definitive diagnosis in county- and city-level medical institutions and county-level centers for disease control and prevention. Conclusions The imported P. malariae and P. ovale malaria cases in Anhui Province, Hubei Province, Zhejiang Province, Henan Province and Guangxi Zhuang Autonomous Region from 2014 to 2021 were mainly returned from Africa and the proportion of correct diagnosis of P. malariae and P. ovale malaria was low at initial diagnosis. Persistent improvements in the diagnostic capability of malaria are required in medical institutions.
