Methods Chinese-funded institutions selected their staffs to receive training on malaria vector control. Using the cluster sampling method, a questionnaire survey was conducted among all 134 trainees before the training course started. The trainer taught the knowledge of malaria vector control face to face using PPT (PowerPoint), and the trainees learned about the principal vector of malaria in Sierra Leone, Anopheles gambiae, and its characteristics and habits through the study of mosquito specimens. After the training, the questionnaire of malaria vector control knowledge was used again to evaluate the training effect. The results of questionnaire survey were analyzed statistically using the t test and chi-square test. Results The mean awareness score of mosquito vector control knowledge was 31.46±20.68 before training and 85.98±16.33 after training, with a significant improvement (F=565.636, P<0.001). The investigation showed that the malaria infection rate average among trainees in the past year was 29.10%, significantly higher in outdoor workers than in indoor workers (37.40% vs 5.70%, χ2=12.561, P<0.001). The analysis of correlation between trainees' pre-training scores and malaria infection rate showed that compared with the highly educated staffs, those with a lower education level had the lower mean score and a significantly higher malaria infection rate (χ2=6.152, P=0.046). The pre-training scores showed a negative correlation with the malaria infection rate. Conclusion In Sierra Leone, the training on mosquito vector control knowledge should be strengthened among the staff members of Chinese-funded institutions, especially those working outdoors and those with a lower education level. Training plans should be developed based on local mosquito vector surveillance data and malaria epidemic situation, and training on relevant mosquito vector control knowledge should be conducted regularly for the Chinese staffs abroad so that they can protect themselves from mosquito-borne diseases such as malaria. %U http://www.bmsw.net.cn/EN/10.11853/j.issn.1003.8280.2020.03.007
