| 1986年1~3月份山西运城地K爆发流行性喘憋性肺炎,罹患率为13.77‰(校正罹忠率为17.50‰),病人多为婴幼儿,其中〇~岁组罹患率最高(89.06‰),1~岁组次之(55.7‰),随年龄增民,罹患率下降。性别间发病男性大于女性(χ2=101.09,P<0.00l),男女之比为1.4:1。病人临床表现一般较重,多数具有喘憋症状,病死率为1%。病人分布具苻家庭聚集性.其爆发与气温有关(rs=0.4799,P<0.05),日温差大,发病人数增多;与人均居室面积大小有关,随居室面积增大,罹患率下降(趋势χ2=5.58,P<0.05)。病原学和血清学研究证明,引起爆发的病原体为呼吸道合胞病毒(RSV)。 |

During January to March in 1986, there was an outbreak of epidemic bronchiolitis in Yun-chen, Shanxi province. Thirteen counties and cities we re involed in Yunchen. On the basis of a survey in 7 counties, there were 6070 cases, with the attack rate of 13.77‰. Most patients were infants and young children. The highest attack rate was in 0~age-group (89.06‰), next wasn 1~age-grouo (55.71‰). The attack rate decreased with the increase of age. The lowest attack rate was in the 10~age-group (0.53‰). The attack rate in males was higher than that ia females (χ2=101.09, P<0.01), and the sex ratiu (males to females) was 1.4:1. The clinical symptoms of most patients were serious. Most patients (75.7%) had symptoms of obstructive asthma. In this outbreak,the fatality rate was one percent. Family aggregation of this outbreak of epidemic bronchiolitis was foujid by binom;nal distribution method (χ2=9.51 P<0.05).
Both etiologic and serologic studies showed that the major pathogen causes this epidemic bronchiolitis was RSV. The risk factors in this outbreak were studied. It appeared that the outbreak of epidemic bronchiolitis was related to the variation of temperature:the bigger variation of daily temperature, the more the cases were found (rs=0.4799,P<0.05).
The occurrence of the disease was also related average space in the house each person had. The smaller the house, the higher attack rate it showed(trend χ2=5.58, P<0.05). |
