Doctor's advice about coronavirus:
醫生關於新型冠狀病毒的建議：

1. It is pretty large in size (cell is about 400-500nm diameter), so any normal mask (not just the N95 feature) should be able to filter it out.
However, when someone who's infected sneezes in front of you, it will take a great 3 meters (about 10 feet) before it drops to the ground and is no longer airborne.
1. 病毒細胞直徑大約400-500納米，任何正常口罩（不一定是N95類型）都可以將病毒細胞過濾出去。當感染者在你面前打噴嚏，病毒細胞會經過橫向距離為3米的拋物線落在地上，之後才會不經過空氣傳播。

2. When the virus drops on metal surface, it will live for at least 12 hours. So remember if you come in contact with any metal surface, wash your hands with soap thoroughly.
2. 當病毒細胞落在金屬表面後會存活12個小時。所以如果你觸碰了金屬表面的話，請記得認真用肥皂或者洗手液洗手。

3. The virus can remain active on fabric for 6-12 hours. Normal laundry detergent should kill the virus. For winter clothing that does not require daily washing, you can put it out under the sun to kill the virus.
3. 病毒在布料上可以存活6到12個小時。普通的洗衣液即可殺死病毒。如果是在衣物無需每天清洗的冬天，將衣服放在太陽下曬一曬可以有助於殺死病毒。
