1988年8月至1991年6月在我院婴儿室及儿科病房发生和收治鼠伤寒沙门氏菌病153例,其中108例占64.1％为医院内感染。发病率龄以12个月以内婴幼儿为主占85.6％。连续两年于8月份在婴儿室呈爆发流行共48例占44.4％。本病全年均可发病,以8～10月为发病高峰。医院内感染的主要传染源为院外感染的散发病例收住院的患者及陪住家属的带菌者。消毒隔离制度不严格是引起传播的重要因素。该病原菌耐药性强,尤其院内感染菌株。院内感染延长住院时间,增加病人痛苦及经济负担,因此医院内感染必须引起重视,急待控制。
From August 1988 to June 1991, 153 cases of Salmonella typhimurium occurred and were treated in infants’ room and pediatric ward in our hospital, of which 108 cases accounted for 64.1% of nosocomial infections. The incidence of age to 12 months of infants and young children accounted for 85.6%. For the second consecutive year, 48 cases (44.4%) were prevalent in the infant room in August. The disease can be disease throughout the year to 8 to 10 peak incidence. The main source of infection in nosocomial infections for hospitalized patients admitted to hospital and accompanying family members carriers. Disinfection and isolation system is not strictly caused by the spread of an important factor. The pathogenic bacteria resistance, especially in-hospital infections. Nosocomial infections prolong the length of hospital stay and increase patient suffering and financial burden. Therefore, infection in the hospital must be given priority so that it can be controlled urgently.
