摘要:
Objective: to analyze the specific prevalence of hand, foot and mouth disease (HFMD) in MaJuqiao Town, Tongzhou District, Beijing during 2018-2020, and to analyze the main causes of the current epidemic infection, so as to make relevant preparations for subsequent disease control and epidemic prevention and control, so as to control the epidemic to a minimum. Methods: we collected data and case information on the incidence of HFMD in Tongzhou District, Beijing from 2018 to 2020, and analyzed the prevalence of HFMD in this period using epidemiological methods and models.. The distribution of infection was 46 positive specimens, with a positive rate of 82.14%. Among the positive samples, CV-A6 accounted for 86.9% (40 cases), CV-A16 accounted for 6.5% (3 cases), and other enteroviruses accounted for 6.5% (3 cases), which was basically consistent with the epidemic trend in Beijing. From 2018 to 2020, a total of 20 cases of HFMD clusters were reported, involving 47 cases. In 2018 and 2019, 18 cases and 2 cases were reported respectively. Most of the outbreaks occurred in nurseries, involving 17 cases, accounting for 85.00%, and 3 cases occurred in family clusters, accounting for 15.00%. Conclusion: the incidence of HFMD in MaJuqiao Town has been effectively controlled gradually from 2018 to 2020, but so far the main population of HFMD is still concentrated in children aged 5 years and below. The temporal variation trend was bimodal, and the peak was from May to August. CV-A6 and CV-A16 were the main pathogens. The main places where cluster outbreaks occur are nursery institutions and families.
