> If you are healthy, you only need to wear a mask if you are taking care of a person with suspected 2019-nCoV infection.
The World Health Organization still recommends that you wear masks only if you're taking care of someone with COVID-19. Why is it so?
Like if the evidence is so clear, why aren't they advising the general public about this? (PS. non-native english speaker, ignore poor english)
