ABSTRACT
Objective To understand the laboratory technicians’ abilities in blood slide making and reading in 10 prefectures of Yunnan Province which have passed the provincial malaria elimination evaluation, so as to provide the evidence for improving the malaria elimination surveillance and parasite examination. Methods Thirty negative blood slides were randomly sampled to evaluate coating, dyeing and clean quality and reading results, and 4 laboratory technicians were sampled to evaluate their reading abilities from each prefecture level and its 2 subordinate counties (districts) respectively, and then the results were analyzed. Results A total of 869 negative blood samples were evaluated. The coincidence rate was 100%. The proportions of good coating, dyeing and clean quality were 96.09%, 91.71% and 96.89%, respectively. Totally 576 blood slides were used to evaluate the reading ability. The number of correct reading was 505, and the correct rate was 87.67%. Among them, the Plasmodium vivax correct reading rate was 87.76%, the P. falciparum correct reading rate was 87.50%, and the correct reading rate of mixed infections was 47.62%. The laboratory technicians’ ability to the mixed infections was significantly lower than the ability to the others (χ2 = 37.169, P < 0.05), however, in the laboratory technicians’ abilities, there was no significant difference among the center (s) for disease control and prevention, general hospitals and township hospitals (χ2 = 2.782, P > 0.05), and the prefecture, county and township levels (χ2 = 0.358, P > 0.05) . Conclusion The 10 prefectures have passed the provincial evaluation in blood slide making and microscopic examination skill indicators requested, but the medical and public health institutions at all levels still should further improve their laboratory technicians’ abilities in blood slide making and microscopic examination skills.

ABSTRACT
OBJECTIVE: To introduce the application of the network training on clinicians' knowledge of malaria diagnosis and treatment in Yunnan Province, and evaluate its effect. METHODS: Through the platform Yiboshi (www.yiboshi.com), the medical and health personnel at the units of provincial, prefectural, county levels and 25 townships of 25 border counties were trained on the knowledge of malaria diagnosis, treatment, prevention and control, and the effects were evaluated by examinations, questionnaires and interviews. RESULTS: Totally 7 152 participants were trained, the average participation, completion and pass rates of the training were 95.26%, 98.55% and 97.30%, respectively. The trainees mainly learned malaria control knowledge from 3 aspects, namely policy of malaria elimination, malaria epidemiology, malaria diagnosis and treatment. The questionnaires showed that 95.94% of the participants considered that their theoretical and technical levels improved, 97.30% were interested in the training content, 93.24% recognized the arrangement of the training time was reasonable, and 91.89% were satisfied with the service of the platform. CONCLUSIONS: The network training on knowledge of malaria diagnosis and treatment in Yunnan Province has achieved good effect. The network training meets the need of training a large number of clinicians in the malaria elimination and post-elimination stage.
