ABSTRACT
Objective:To analyze the epidemic characteristics of Cornona virus disease 2019 (COVID-19) in Wangkui County, Heilongjiang Province, and to provide a reference for optimizing epidemic prevention and control strategies.Methods:The epidemic characteristics of COVID-19 in Wangkui County, Heilongjiang Province in January 2021 were analyzed by applying the national infectious disease report system and information management system of Heilongjiang Provincial Center for Disease Control and Prevention, the public health emergency report management information system, the epidemiological investigation report of the Heilongjiang Provincial Center for Disease Control and Prevention and Suihua Municipal Certer for Disease Control and Prevention, and the epidemic information publicly released by the Health Commission of Heilongjiang Province.Results:From January 9 to February 5, 2021, 804 cases infected with Cornona virus were reported in Wangkui County, with an infection rate of 280.29/100 000. The epidemic affected 20 districts and counties in 6 cities, including Suihua, Harbin, Mudanjiang, Qiqihar, Yichun and Daqing. The sex ratio of male to female was 1.08 ∶ 1.00 (418 ∶ 386), the age ranged from 3 months to 93 years old, and the median age was 50 years old. The proportion of confirmed cases and asymptomatic infection was 1.23 ∶ 1.00 (444 ∶ 360), there were significant differences in gender, age and occupation between them ( P < 0.05). There were 314 places where the aggregation epidemic occurred, with family aggregation as the main way (300 households, 95.54%). The places with the highert average number of cases were banquets (25.75 cases/place) and grocery stores/chess and card rooms (16.00 cases/place). Conclusions:In January 2021, the epidemic of COVID-19 in Wangkui County is a typical outbreak in rural areas of North China. The main reasons for the rapid spread of the epidemic are a large number of gathering activities, frequent contact of personnel in confined spaces and other factors.
ABSTRACT
Objective To study the relations between famine exposure and the risk of chronic diseases as diabetes mellitus,obesity,hypertension,coronary heart disease and stroke in the population of Harbin.Methods Our data was collected from the baseline survey-the China Kadoorie Biobank project (CKB) in Harbin.Retrospective cohort study design was used.Related risks on chronic diseases including diabetes mellitus,obesity,hypertension,coronary heart disease and stroke,were compared among the famine exposed or non-exposed people,respectively by logistic analysis method.Results After adjusted for factors as age,sex,physical activity,smoking,alcohol intake,diet,family history of diseases,it appeared that the factor ‘ famine exposure'had increased the risks of diseases as obesity (OR=1.204,95％CI:1.104-1.313,P＜0.01),hypertension (OR=1.315,95％CI:1.210-1.429,P＜0.01) and coronary heart disease (OR=1.495,95％CI:1.369-1.632,P＜0.01).The lower the age of population being exposed to famine,the greater the risk of the development of all kinds of chronic diseases.Conclusions Famine exposure appeared a risk factor for obesity,hypertension,and coronary heart disease.It is of great significance to ensure the life-long nutrition of the people,especially in the early and adolescent stages,to prevent obesity,hypertension,and coronary heart disease in their later lives.
