Abstract: Objective  To evaluate the professional capacity of personnel in parasitic disease prevention and control in the Centers for Disease Control and Prevention in Chongqing City in order to facilitate construction of the local institutions in parasitic disease prevention and control. Methods The personal information and competition results of all contestants participated in Chongqing Parasitic Disease Prevention and Control Technology Competition were collected from 2016 to 2021 except 2020 (cancelled due to COVID-19 epidemic). The competition consisted of theoretical examination and skill operation. SPSS 19.0 was used to statistically analyze the competition results, and U-test or H-test was used to compare the results of different contestants. Results  The participants were all from 38 districts (counties) within Chongqing City. Between 2016 and 2021, the number of participants was 73, 73, 78, 76 and 84 respectively. Female constants were more than male ones in each year, and the academic titles were generally junior professionals. The working areas were primarily in the regions directly under jurisdiction of Chongqing. In 2016, only personnel from disease control institutions participated in the competition. In 2017, personnel from medical institutions began to participate in the competition. By 2021, the number of participants from medical institutions exceeded that of those from disease control institutions for the first time. From 2016 to 2021, the median of total scores of competitors was 83.50, 77.00, 88.00, 81.00 and 94.95 respectively, and the median scoring on skills and theory was 34.00, 31.00, 36.00, 26.00 and 40.40; and 47.00, 45.00, 50.50, 53.00 and 55.25 respectively. Comparison of the total scores and scoring on the theory and skills in different groups in 2016 showed that female contestants had higher scoring on theoretical tests and operational skills using Kato-Katz technique than that of males. The difference was significant (U=753.50, 775.50, both P<0.05). The theoretical scores of the contestants from municipal districts were higher than those from counties under municipal jurisdiction, with statistical difference (U=379.50, P=0.04). In 2018, contestants from municipal districts had higher scores on the theory than those from counties under municipal jurisdiction (U=410.00, P=0.03). In 2019, female contestants scored higher on production of microscopic specimens for plasmodium detecting than the male contestants (U=775.50, P=0.01). In 2021, the total scores of personnel with middle and senior academic titles and the results of malaria microscopy were higher than those of personnel with primary and lower academic titles (H=6.65, 6.81, both P<0.05), and the results of malaria microscopic examination were better in contestants from hospitals than those from CDC (U=1 134.00, P=0.02). Conclusion The theoretical knowledge and ability of specimen production are generally better in the contestants from parasitic disease control institutions in Chongqing City, yet the skills in microscopic examination of helminths and plasmodium need improving. The professionals at grass-root organizations are supposed to be strengthened in boosting their capacity in parasitic disease control.
