哪些是过度消毒？
一般情况下，车轱辘消毒、楼道空气消毒、鞋底消毒、快递外卖包装消毒、空旷地面消毒，都属于过度消毒。
如果有明确的局部环境受到了传染源污染，用消毒剂做一次性终末消毒就够了。大面积反复喷洒消毒剂存在环境污染的风险，一定要避免。
日常居家没必要频繁消毒
如果家中没有陌生人进屋，没有疫区回来的亲戚朋友串门，没有病人，也没有人感到身体不适，不必频繁消毒。
常通风、勤洗手、做好清洁即可。
Tips on disinfection (Part 2)
Unnecessary disinfection
It is unnecessary to disinfect such items as tires, shoes, and packages of express delivery or take-away food or sterilize air in the corridor or open ground.
A terminal disinfection will suffice when a certain area is contaminated by an infection source. Repeated spraying of disinfectants on large areas poses a risk to the environment and must be avoided.
Unnecessary frequent disinfection at home
Frequent disinfection is not necessary if you have:
1. No stranger visiting your house;
2. No friend or relative back from the epidemic areas;
3. No family member diagnosed with COVID-19;
4. Or no one feeling unwell.
Keep your rooms well ventilated, wash your hands frequently, and maintain good hygiene.
