【摘要】：目的通過對(duì)一起諾如病毒感染性腹瀉疫情的調(diào)查處置,了解疫情發(fā)生發(fā)展特點(diǎn),分析引起暴發(fā)的各種因素,探討控制措施。方法對(duì)某殘疾人托管中心相關(guān)病例開展現(xiàn)場(chǎng)流行病學(xué)調(diào)查,用熒光PCR法檢測(cè)病人糞便樣本。結(jié)果調(diào)查共發(fā)現(xiàn)患者54例,罹患率為13.78%(54/392),其中托管對(duì)象罹患率為18.82%(51/271),工作人員罹患率為2.48%(3/121),兩者差異有統(tǒng)計(jì)學(xué)意義(P0.05)。托管對(duì)象中男性發(fā)病30例,女性發(fā)病21例,男女罹患率差異無統(tǒng)計(jì)學(xué)意義(P0.05)。病例采樣15例經(jīng)熒光定量RT-PGR檢測(cè),結(jié)果 14例患者諾如病毒Ⅱ型陽性。通過集中隔離治療、環(huán)境消毒、獨(dú)立洗滌用品和健康教育等措施,疫情在一個(gè)最長(zhǎng)潛伏期內(nèi)得以控制。結(jié)論諾如病毒通過多種途徑易在集體生活人群中發(fā)生,發(fā)生疫情及時(shí)采取綜合控制措施可以避免疫情擴(kuò)散。
[Abstract]:Aim to investigate and dispose a case of norovirus infectious diarrhea, understand the characteristics of occurrence and development of the epidemic situation, analyze the factors causing the outbreak, and discuss the control measures. Methods Epidemiological investigation was carried out on the related cases in a care center for the disabled. Fluorescent PCR method was used to detect the fecal samples of the patients. Results A total of 54 patients were investigated, and the attack rate was 13.78% (54 / 392), of which 18.82% (51 / 271) were in custody and 2.48% (3 / 121) in staff. The difference was statistically significant (P0.05). There were 30 males and 21 females. There was no significant difference in the incidence rate between males and females (P0.05). 15 cases were detected by fluorescence quantitative RT-PGR. The results showed that 14 cases were positive for norovirus type 鈪，
