炎炎夏日,如何防范空调杀手——“军团菌”

2018-08-09 沈波 江苏感控之窗

军团菌为需氧革兰阴性杆菌,广泛存在于自然界水源中,在适宜环境中,如31-36℃水中可长期存活,在普通自来水中可存活400天以上。而集中空调冷却塔的典型温度是29℃-35℃,非常适宜军团菌的生长。

盛夏时节,持续高温,家家户户都开启了空调。殊不知,伴随着空调吹来的习习凉风,隐形杀手——军团菌,也悄悄向我们袭来。大量国内外研究显示,集中空调是常见引发军团病流行与传播的重要因素。军团病是由军团菌属细菌引起的临床综合征。因1976年美国费城召开退伍军人大会时暴发流行而得名。军团病近年来并非少见,研究资料显示,欧洲2009年共有5551例军团菌病例报道,发病率为1.07/10万;2010年发病数字提高到6305例,发病率升至1.2/10万;2015年8月,美国纽约暴发的军团病导致近百人感染,并出现7例死亡。50岁以上、吸烟、有慢性疾病或免疫功能低下者更容易感染。军团菌感染后病死率较高,可达10%,但在医疗机构获得的病死率更高,可达25%。

军团菌为需氧革兰阴性杆菌,广泛存在于自然界水源中,在适宜环境中,如31-36℃水中可长期存活,在普通自来水中可存活400天以上。而集中空调冷却塔的典型温度是29℃-35℃,非常适宜军团菌的生长。因此,医院总务或后勤保障部门应根据WS/T 396—2012《公共场所集中空调通风系统清洗消毒规范》的要求,对集中空调通风系统进行定期清洗消毒,具体方法如下:


最后,集中空调系统清洗、消毒后7日内,由经培训合格的检验人员按照有关卫生要求进行检验,不具备检验能力的也可以委托检验。
