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. Enhance indoor environment cleaning and ventilation through Windows can reduce respiratory diseases.There is no evidence of airborne transmission of COVID-19.If there is a member of the family who needs home health monitoring, it is necessary to disinfect the room.

In daily disinfection, specific measures can be taken:

1. Choose to use 500mg/L chlorine-containing disinfectant and 0.3% peroxyacetic acid disinfectant to wipe and disinfect. It is not recommended to spray disinfection when there are people in the room.

與流感相比，新冠病毒更易于傳播，主要傳播途徑為經呼吸道飛沫和密切接觸傳播，接觸病毒污染的物品也可造成感染，在相對封閉的環境中長時間暴露于高濃度氣溶膠情況下存在經氣溶膠傳播的可能。

這就對個人日常消毒提出了具體的要求。，如果家庭成員無新冠肺炎疑似、確診病例或無癥狀患者接觸史，或居住小區未發現上述病例，不用在家居消毒上特別費心，加強室內環境清潔和開窗通風可減少呼吸道疾患。目前尚無新冠肺炎病毒通過空氣傳播的證據。如果家里有需要居家健康監測的成員，有必要對室內進行消毒。

日常消毒中，具體可以采取這些措施：

1.選擇使用500mg/L含氯消毒劑和0.3%過氧乙酸消毒劑進行擦拭消毒，室內有人的情況下不建議噴灑消毒。

2.每天清潔、消毒家庭成員經常觸碰的物品，如床頭柜、床架、門把手等進行擦拭消毒1-2次；電子設備采用75%的酒精擦拭消毒。

3.每天清潔、消毒浴室和廁所表面1-2次；

4.用洗衣機常規洗滌衣物，最好能將水溫設定為56℃以上，洗滌時間大于30分鐘，然后晾干或高溫烘干；5.接觸居家健康監測成員體液污染的物品后用香皂認真洗手，必要時用含有酒精成分的手消毒液進行手消毒。

消毒劑推薦使用：

1.75%醫用酒精：主要用于金屬用品和電子產品的消毒，如手機、電視機、鑰匙等。不能用酒精噴灑在嬰幼兒和成人身體上，一則容易引起酒精過敏；二則可能引發火災。

2.含氯消毒劑：84消毒液、含氯消毒粉或含氯泡騰片等都屬于含氯消毒劑。居家使用濃度為500mg/L，如含氯泡騰片每1000mL水中放入1片溶解，消毒液濃度就是500mg/L。
