We need to wear a face mask-and also wash our hands-Not just to try and protect our self-We need to wear a mask to stop us spreading the virus.Especially in shops & public transport
If we have a face mask on before we realize we have the virus .If later we are infectious the mask has reduced us spreading the virus to other people directly or indirectly
Where does the virus mainly come from our lungs Every time we cough or sneeze we shower everything and still do not know then we have The Virus.
When we have the virus and cant breathe that is another world
China-South Korea-Hong Kong all appear to wear face masks so why not us.in the West.-Compare the deaths.
