预防和防控诺如病毒幼儿园病毒防控第一课诺如病毒,又称诺瓦克病毒(NorwalkViruses,NV[1])是人类杯状病毒科(HumanCalicivirus,HuCV)中诺如病毒(Norovirus,NV)属的一种病毒。是一组形态相似、抗原性略有不同的病毒颗粒。XXX幼儿园宣讲ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei目录认识诺如病毒诺如病毒的主要症状及传播途径诺如病毒的预防方法诺如病毒的消毒方法01020304ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei认识诺如病毒诺如病毒,又称诺瓦克病毒(NorwalkViruses,NV[1])是人类杯状病毒科(HumanCalicivirus,HuCV)中诺如病毒(Norovirus,NV)属的一种病毒。PART01ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei诺如病毒又称诺瓦克病毒(NorwalkViruses,NV[1])是人类杯状病毒科(HumanCalicivirus,HuCV)中诺如病毒(Norovirus,NV)属的一种病毒。是一组形态相似、抗原性略有不同的病毒颗粒。诺如病毒感染性腹泻在全世界范围内均有流行,全年均可发生感染,感染对象主要是成人和学龄儿童,寒冷季节呈现高发。美国每年在所有的非细菌性腹泻爆发中,60%-90%是由诺如病毒引起。荷兰、英国、日本、澳大利亚等发达国家也都有类似结果。在中国5岁以下腹泻儿童中,诺如病毒检出率为15%左右,血清抗体水平调查表明中国人群中诺如病毒的感染亦十分普遍。ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei诺如病毒的特点:通过接触、水源、食物、呼吸均可传播。❶传染性较强易发于幼儿园、学校等人群集中、密闭的场所。❷以群发为主在中国5岁以下腹泻儿童中,诺如病毒检出率为15%左右。❸儿童易感该病通常为自限性,两三天就会好转,预后良好,因此不必过度恐慌。❹自限性疾病ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei诺如病毒并非新型病毒诺如病毒,又称诺瓦克病毒(NorwalkViruses,NV),自1968年在美国被发现后,1995年国内出现首例,并非新型病毒。诺如病毒主要造成胃肠道感染,诺如病毒感染性腹泻在全世界范围内均有流行,感染对象主要是成人和学龄儿童,全年均可发生感染,但寒冷季节尤为多发。ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiPART02诺如病毒的主要症状及传播途径诺如病毒,又称诺瓦克病毒(NorwalkViruses,NV[1])是人类杯状病毒科中诺如病毒(Norovirus,NV)属的一种病毒。ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei发病时间:潜伏期多在24-48小时,最短12小时,最长72小时。发病时间:临床表现与其他病毒性胃肠炎相似,起病突然,主要症状为发热、恶心、呕吐、痉挛性腹痛及腹泻。可单有呕吐或腹泻,亦可先吐后泻,故也称为诺如病毒感染性腹泻。ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei诺如病毒发病症状:病程长及病情较重者排毒时间也较长,传染性可持续到症状消失后两日。本病免疫期短暂,可反复感染。成人腹泻较突出,儿童呕吐较多。粪便呈黄色稀水便,每日数次至十数次不等,无脓血与黏液。可伴有低热、咽痛、流涕、咳嗽、头痛、肌痛、乏力及食欲减退。ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei诺如病毒的主要传播途径:诺如病毒感染性强,以肠道传播为主,感染主要原因有:●食用诺如病毒污染的食物,饮用诺如病毒污染的水或饮料。●接触诺如病毒污染的物体或表面,然后手接触到口。●直接接触感染者,如照顾病人、与病人共餐或使用相同的餐具等。ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiPART03诺如病毒的预防方法诺如病毒,又称诺瓦克病毒(NorwalkViruses,NV[1])是人类杯状病毒科中诺如病毒(Norovirus,NV)属的一种病毒。ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei来自中国疾控中心权威建议:个人卫生、食品卫生和饮水卫生是预防的关键。应养成勤洗手、不喝生水、生熟食物分开避免交叉感染等健康生活习惯。ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei诺如病毒的预防方法:●养成良好的卫生习惯,勤洗手,并且要用肥皂或流动水洗手,尤其是饭前和便后以及外出归来后。●不吃生食、半生食海鲜及肉类,生熟食物分开放置、避免交叉感染,不喝生水,水果要彻底清洗干净后方可食用。●尽量避免带幼儿到没有卫生保障的公共场所用餐。●尽量避免带幼儿去人多拥挤的公共场所,如电影院、聚会场所、大商场等。●如家中发现疑似患儿,要对其呕吐物的污染处进行消毒处理,建议家长可以用84消毒液浸泡污染物30分钟以上,室内通风1小时以上,在操作时尽量戴上橡胶手套或一次性手套,避免交叉感染。ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei孩子这样做:注意个人卫生习惯,勤洗手,特别是饭前便后,外出回家后;尽量用洗手液或肥皂、流动水洗净要有经常运动的意识,从而增强自身的抵抗力保证充足睡眠,不挑食,从而增强自身免疫力。010203ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei家庭预防措施:●养成良好的卫生习惯,勤洗手,并且要用肥皂或流动水洗手,尤其是饭前和便后以及外出归来后。●不吃生食、半生食海鲜及肉类,生熟食物分开放置、避免交叉感染,不喝生水,水果要彻底清洗干净后方可食用。●尽量避免带幼儿到没有卫生保障的公共场所用餐。●尽量避免带幼儿去人多拥挤的公共场所,如电影院、聚会场所、大商场等。●如家中发现疑似患儿,要对其呕吐物的污染处进行消毒处理,建议家长可以用84消毒液浸泡污染物30分钟以上,室内通风1小时以上,在操作时尽量戴上橡胶ploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjeiploch1hddqosaidojclk7nwqkjhjzzassiasd1naskh0kjei幼儿园预防措施:●坚持做好每日晨、午检工作,认真执行一摸、二看、三问、四查的原则,发现异常情况及时处理。●班级教室每天坚开窗通风2-3次,每次不少于20分钟,降低室内空气中微生物的数量,改善室内空气质量。●培养幼幼儿园儿
