The reason it's necessary to wear masks during Covid1-9 is to prevent the spread of the Covid-19 virus through droplets by sneezing, coughing and simply talking.
The mask prevents you from getting the Covid-19 virus as well as prevents you from spreading it to others just in case you may have Covid-19 and not know it.
Eventually this pandemic for Covid-19 will be over hopefully within the end of 2022 or 2024 but for now we should still wear our face masks.
Yes masks are effective against the coronavirus disease.
The Covid-19 Virus or disease is spread through droplets that come out of a persons nose and mouth and then those droplets go through the air.
Even when someone simply speaks they can spew the Covid-19 virus out of their body which then gets in the air and then you breathe it in.
Then if you're not vaccinated against Covid-19 you can get the virus yourself.
Having Covid-19 is not always serious for everyone but the Covid-19 virus is much more serious than the simple flu.
When you wear the face masks you prevent yourself from getting Covid-19 as well as the flu or cold virus.
Since I started wearing masks during the Covid-19 pandemic I have not gotten Covid-19 or even the normal cold or flu virus.
Usually I get sick with the flu and cold at least 3 times per year but this year so far I have not had the cold or flu.
So I will continue wearing the face masks.
