Tips for living in novel coronavirus-infected communities (Part 2)
1. How many days could the novel coronavirus stay alive outside the human body?
Studies have found that the virus can remain active for several hours on smooth surfaces such as door handles and elevator buttons. With appropriate temperature and humidity, it may survive for several days. So it is important to wash your hands.
2. Is it possible that the virus sticks to quilts airing on a sunny day?
No, it isn’t. Studies have shown that sunlight can help reduce the activity and survival time of the virus under dry and hot conditions with good airflow accompanied by ultraviolet light.
3.Why should we keep rooms well ventilated? Will the viruses find their way into the house through airborne dust?
Increased ventilation lowers the concentration of viruses in the indoor air while the concentration of viruses outdoors is in itself relatively low as the viruses are exposed to ultraviolet light in a large and open space.
4. How should I disinfect my clothes at home after going outside?
If you do not contact people exposed to the novel coronavirus, you can change your clothes at appropriate intervals. For extra precautions, you can use alcohol spray to sanitize coats. If not available, use any alcoholic drinks with an ABV between 70%-75%.
5. Are there any other ways to sanitize laundry?
Alternative ways of disinfecting clothes based on information on the SARS virus are as follows:
(1) Put into a dryer at a temperature between 56-75℃ for 30-90 minutes;
(2) Get exposed to an ultraviolet lamp for 60 minutes;
(3) Soak in chlorine disinfectant for 5 minutes;
(4) Air for 3 days outdoors;
(5) Hang-dry in the sunshine for more than 60 minutes.
小区有人感染新型冠状病毒,怎么办?(下篇)
1. 新冠病毒在体外环境能存活几天?
研究发现,病毒在门把手、电梯按钮等光滑的物体表面,可存活数小时。
如果温度、湿度合适,可能存活数天。
所以,洗手非常重要。
2. 太阳出来时晒被子,是否有被污染的风险?
晒被子不用担心被污染。
研究显示:受干燥、热、通风和紫外线等综合作用的影响,阳光下,病毒的活性和存活时间都会降低。
3. 为什么要通风?病毒会沾着灰尘飘进家里吗?
通风能降低室内病毒的浓度。
而室外空间大,还有紫外线,病毒的浓度相对更低。
4. 外出回家后,怎么对衣物消毒?
一般不接触危险人群的话,衣物正常换洗即可。
实在担心,也可用酒精喷洒外套消毒。
没有酒精,浓度70%-75%的酒也可以。
5. 除了酒精,还有什么给衣物消毒的方法?
参考以往对SARS病毒的研究,有这几种方法:
(1)合适温度(56-75°C)和时间(30-90分钟)的烘干机;
(2)用紫外线灯照60分钟;
(3)含氯消毒液浸泡5分钟;
(4)窗外自然环境通风3天;
(5)太阳下晾晒60分钟以上。
