哪些是過度消毒？
一般情況下，車轱轆消毒、樓道空氣消毒、鞋底消毒、快遞外賣包裝消毒、空曠地面消毒，都屬于過度消毒。
如果有明確的局部環境受到了傳染源污染，用消毒劑做一次性終末消毒就夠了。大面積反復噴灑消毒劑存在環境污染的風險，一定要避免。
日常居家沒必要頻繁消毒
如果家中沒有陌生人進屋，沒有疫區回來的親戚朋友串門，沒有病人，也沒有人感到身體不適，不必頻繁消毒。
常通風、勤洗手、做好清潔即可。
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.
