It is also possible to be infected by the new coronavirus by wearing a mask.
Since novel coronaviruses are mainly transmitted through respiratory droplets, wearing a mask can effectively prevent oneself from being infected with novel coronaviruses. However, wearing a mask is not 100% effective in preventing infection. If you do not wear a mask correctly, or if you wear a mask in close contact with an infected person, you may still be infected with the novel coronavirus.
There is no way to achieve 100% prevention of infection with the novel coronavirus, but vaccination, wearing masks, washing hands frequently, and avoiding crowded areas can effectively reduce the likelihood of infection with the novel coronavirus.
If you are suspected to be infected with novel coronavirus, it is recommended that you seek medical attention promptly.
