Résumé
【Objective】 To analyze the epidemiological characteristics of pertussis in Shaanxi Province from 2012 to 2021. 【Methods】 We collected the information of pertussis cases in Shaanxi Province from 2012 to 2021 by the China Disease Control and Prevention Information System for analyzing the incidence and distribution characteristics. 【Results】 From 2012 to 2021, a total of 8270 cases of pertussis were reported in Shaanxi Province, with the incidence ranging from 0.21 to 6.20 per 100 000 persons, and for an annual average incidence of 2.17 per 100 000 persons. 44.81% (3 706/8 270) occurred from June to September. The annual average incidence in southern Shaanxi, Guanzhong, and northern Shaanxi was 1.78, 2.47, and 1.46 per 100 000 persons (χ2=289.638, P<0.001). The number of patients (proportions) with pertussis aged 0-1, 1-5, 5-10, and ≥10 years was 3 884 (46.96%), 2 869 (34.69%), 1 408 (17.03%), and 109 (1.32%), respectively. The number of patients (proportion) ≤ 2 months old, 3-5 months old, and ≥ 6 months old was 884 (22.76%),1 608 (41.40%), and 1 392 (35.84%) among pertussis patients under 1 year old. 【Conclusion】 The incidence of pertussis in Shaanxi Province basically showed an increasing trend with higher rates between June and September, higher rates in Guanzhong region of the province, and more patients over 5 years old.
Résumé
Objective To study the awareness of Brucellosis prevention knowledge and prevalence of risk behaviors among the primary and secondary school students from breeding livestock’s families in Western pastoral areas of Jilin province,and to provide evidence for the prevention and control of Brucellosis.Methods With application of multi-stage random sampling method,a questionnaire survey which including Brucellosis prevention knowledge and risk behaviors was conducted among 209 primary and secondary school students in west part of Jilin province in 2012.Results 105(50.97%)students had heard Brucellosis among 206 students,the older students knew more about Brucellosis than the younger(χ2 =28.80,P=0.00).The M(Q)of the score of the Brucellosis-related knowledge was 8(6.00,9.00),the total passing rate was 28.64%.72(68.61%)students learned Brucellosis from village doctors and acquaintances,only 11(10.51%)students learned it from school;the contact rates of eight kinds of high-risk behaviors were helping feeding 21.84%(62/206),holding lamb 16.50%(58/206),cleaning sheepfold 8.73%(26/206),vaccinating sheep 5.34%(17/206),milking 2.91%(6/206);cleaning apoblema 2.91%(6/206),slaughtering 2.42%(5/206)and delivering lamb 1.94%(4/206);there was no significant difference between the passing rate and the eight kinds of the basic protective behaviors except feeding (P>0.05).Conclusion The level of Brucellosis prevention knowledge is low in Western pastoral areas of Jilin province, and there was a high-risk of contact behavior with sheep and low basic protection rate. It indicates that the education about prevention and control of Brucellosis in the students from breeding livestork’s familes should be strengthened in order to prevent Brucellosis infection.
