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.

小區(qū)有人感染新型冠狀病毒，怎么辦？（下篇）

1. 新冠病毒在體外環(huán)境能存活幾天？

研究發(fā)現(xiàn)，病毒在門(mén)把手、電梯按鈕等光滑的物體表面，可存活數(shù)小時(shí)。

如果溫度、濕度合適，可能存活數(shù)天。

所以，洗手非常重要。

2. 太陽(yáng)出來(lái)時(shí)曬被子，是否有被污染的風(fēng)險(xiǎn)？

曬被子不用擔(dān)心被污染。

研究顯示：受干燥、熱、通風(fēng)和紫外線等綜合作用的影響，陽(yáng)光下，病毒的活性和存活時(shí)間都會(huì)降低。

3. 為什么要通風(fēng)？病毒會(huì)沾著灰塵飄進(jìn)家里嗎？

通風(fēng)能降低室內(nèi)病毒的濃度。

而室外空間大，還有紫外線，病毒的濃度相對(duì)更低。

4. 外出回家后，怎么對(duì)衣物消毒？

一般不接觸危險(xiǎn)人群的話，衣物正常換洗即可。

實(shí)在擔(dān)心，也可用酒精噴灑外套消毒。

沒(méi)有酒精，濃度70%-75%的酒也可以。

5. 除了酒精，還有什么給衣物消毒的方法？

參考以往對(duì)SARS病毒的研究，有這幾種方法：

（1）合適溫度（56-75°C）和時(shí)間（30-90分鐘）的烘干機(jī)；

（2）用紫外線燈照60分鐘；

（3）含氯消毒液浸泡5分鐘；

（4）窗外自然環(huán)境通風(fēng)3天；

（5）太陽(yáng)下晾曬60分鐘以上。
