目的分析2005—2014年甘肃省定西市安定区报告的5 497例丙类传染病病例,掌握丙类传染病的流行特征,为丙类传染病防控工作提供科学依据。方法收集2005—2014年在中国疾病预防控制信息系统中报告的丙类传染病个案资料,采用描述流行病学方法进行分析比较。结果累计报告5 497例丙类传染病病例,年均发病率为122.81/10万,发病率差异有统计学意义(χ2=1 630.56,P<0.01);死亡1例,平均死亡率0.02/10万;发病前五位的病种为流行性腮腺炎、手足口病、风疹、其他感染性腹泻病、流行性感冒,发病数排在首位的是呼吸道疾病、占64.49%,其次为肠道传染病、占34.82%;第二季度报告病例数最多、占45.46%;各乡(镇)发病率差异有统计学意义(χ2=3 965.23,P<0.01),有8个乡(镇)发病率高于安定区平均发病率,占安定区乡(镇)总数的38.10%;男性发病率高于女性,差异有统计学意义(χ2=142.54,P<0.01);丙类传染病的主要发病人群在15岁以下年龄组,共发病4 975例、占90.50%;职业构成以学生、散居儿童、幼托儿童为主,占病例总数的90.47%。结论流行性腮腺炎、手足口病、风疹、流行性感冒、其他感染性腹泻病是当地丙类传染病病例中的主要构成疾病,今后应重点加强呼吸道和肠道传染病的监测与预防控制工作。
Objective To analyze the 5 497 cases of Category C infectious diseases reported in Anding District, Dingxi City, Gansu Province from 2005 to 2014 and to grasp the epidemiological characteristics of Type C infectious diseases so as to provide a scientific basis for prevention and control of Type C infectious diseases. Methods The data of cases of type C infectious diseases reported in China’s disease control and prevention information system from 2005 to 2014 were collected and analyzed by using descriptive epidemiological methods. Results A total of 5 497 cases of Category C infectious diseases were reported, with an average annual incidence of 122.81 / 100 000. There was a statistically significant difference in incidence between the two groups (χ2 = 1 630.56, P <0.01); 1 case died and the average death rate was 0.02 / 10 Million; the top five diseases were mumps, hand-foot-mouth disease, rubella, other infectious diarrheal diseases, and influenza. The number of diseases in the top five was respiratory diseases, accounting for 64.49%, followed by intestinal infections (34.82%) in the second quarter; the highest reported cases were in the second quarter (45.46%); the incidence of each township was statistically different (χ2 = 3 965.23, P <0.01) Which was higher than that of Anding District, accounting for 38.10% of the total number of townships (towns) in Anding District. The incidence of males was higher than that of females, with significant difference (χ2 = 142.54, P <0.01) In the age group of 15 years old, a total of 4 975 cases occurred, accounting for 90.50%. The occupational composition was mainly composed of students, scattered children and childcare children, accounting for 90.47% of the total cases. Conclusions Mumps, hand-foot-mouth disease, rubella, influenza and other infectious diarrheal diseases are the main diseases in the local cases of Category C infectious diseases. In the future, we should focus on the monitoring and prevention and control of respiratory and intestinal infectious diseases .
