Objective: To investigate the epidemiological characteristics of hand, foot and mouth disease ( HFMD ) in Zhejiang Province, so as to provide insights into HFMD control. Methods: The incidence of HFMD in Zhejiang Province from 2016 to 2019 was collected from National Notifiable Disease Reporting System. The temporal distribution, human distribution, regional distribution and pathogenic typing of HFMD were descriptively analyzed in Zhejiang Province from 2016 to 2019. Results: Totally 642 305 cases with HFMD were reported in Zhejiang Province from 2016 to 2019, including 121 severe cases and 9 fatal cases. The annual incidence of HFMD was 335.88/105, 147.76/105, 435.63/105 and 221.77/105, respectively. The incidence of HFMD peaked from May to July each year, and the three highest annual incidence included Ningbo, Jinhua and Wenzhou cities, while the lowest annual incidence was seen in Zhoushan City. The HFMD cases were predominantly found in children at ages of 1 to 5 years ( 537 738 cases, 83.72% ), and in children living at home ( 419 408 cases, 65.30% ). The average annual incidence of HFMD was higher in males than in females ( 328.23/105 vs. 239.99/105; P<0.05). The dominant pathogens gradually shifted from enterovirus 71 ( EV71 ) to Coxsachievirus A16 ( CA16 ), and other enteroviruses remained as the main pathogenic subtypes. Conclusions The incidence HFMD was high in summer and autumn in Zhejiang Province from 2016 to 2019. Children living at home are at a high risk of HFMD, and CA16 type gradually became the dominant pathogen of HFMD.

Objective: To investigate the development of public health human resource of the Centers for Disease Control and Prevention (CDCs) in Zhejiang Province from 2016 to 2020, so as to put forward the strategies for the talent team construction of CDCs. Methods: The general information of personnel of CDCs in Zhejiang Province from 2016 to 2020 was collected through China Information System for Disease Control and Prevention. A questionnaire survey and a qualitative interview were conducted to collect the data of staffing, talent training, salary and employee turnover, and to analyze the development of the talent team of CDCs. Results: By 2020, there were 105 CDCs, including 1 provincial, 11 prefectural and 93 county-level CDCs, and 5 277 staff on-the-job. From 2016 to 2020, the number of staff per 10 000 permanent residents in the province, prefecture and county levels were 0.062-0.070, 0.170-0.188 and 0.585-0.604, respectively, which did not meet the standard for the personnel establishment in Zhejiang CDCs; the proportion of the staff with bachelor degree or above increased from 90.05% to 94.25%; the proportion of the health professionals decreased from 82.91% to 80.01%; the proportion of the staff with senior professional titles increased from 35.20% to 45.25%. The results of the qualitative interview indicated a lack of health professionals and high-end talents, a gap between the approved staffing and post requirements, as well as demands for a stable team and higher pay. Conclusion From 2016 to 2020, the structure of educational background, major and professional title among the on-the-job staff of CDCs in Zhejiang Province has been improving; however, the total allocation of human resource is insufficient, and the stability and treatment of staff need to be further improved.
