Compared with influenza, novel coronavirus is more easy to spread, the main way of transmission is via respiratory droplets and close contact transmission, contact virus contaminated articles can also cause infection, in the relatively closed environment for a long time exposed to high concentration of aerosol in the presence of the possibility of aerosol transmission.

This puts forward the specific request to the individual daily disinfection.. If family members have no contact history of suspected or confirmed cases of COVID-19 or asymptomatic patients, or no such cases have been found in the residential area, there is no need to make special efforts to disinfect the home.

In daily disinfection, specific measures can be taken:

与流感相比，新冠病毒更易于传播，主要传播途径为经呼吸道飞沫和密切接触传播，接触病毒污染的物品也可造成感染，在相对封闭的环境中长时间暴露于高浓度气溶胶情况下存在经气溶胶传播的可能。

这就对个人日常消毒提出了具体的要求。，如果家庭成员无新冠肺炎疑似、确诊病例或无症状患者接触史，或居住小区未发现上述病例，不用在家居消毒上特别费心，加强室内环境清洁和开窗通风可减少呼吸道疾患。目前尚无新冠肺炎病毒通过空气传播的证据。如果家里有需要居家健康监测的成员，有必要对室内进行消毒。

日常消毒中，具体可以采取这些措施：

1.选择使用500mg/L含氯消毒剂和0.3%过氧乙酸消毒剂进行擦拭消毒，室内有人的情况下不建议喷洒消毒。

2.每天清洁、消毒家庭成员经常触碰的物品，如床头柜、床架、门把手等进行擦拭消毒1-2次；电子设备采用75%的酒精擦拭消毒。

3.每天清洁、消毒浴室和厕所表面1-2次；

4.用洗衣机常规洗涤衣物，最好能将水温设定为56℃以上，洗涤时间大于30分钟，然后晾干或高温烘干；5.接触居家健康监测成员体液污染的物品后用香皂认真洗手，必要时用含有酒精成分的手消毒液进行手消毒。

消毒剂推荐使用：

1.75%医用酒精：主要用于金属用品和电子产品的消毒，如手机、电视机、钥匙等。不能用酒精喷洒在婴幼儿和成人身体上，一则容易引起酒精过敏；二则可能引发火灾。

2.含氯消毒剂：84消毒液、含氯消毒粉或含氯泡腾片等都属于含氯消毒剂。居家使用浓度为500mg/L，如含氯泡腾片每1000mL水中放入1片溶解，消毒液浓度就是500mg/L。
