Can wearing masks stop the spread of viruses?

They could help stop the spread of viruses, but not for the reason ordinary people say they use masks: that they protect against viruses or bacteria carried in the air

Dr David Carrington, of St George’s, University of London, told BBC News “routine surgical masks for the public are not an effective protection against viruses or bacteria carried in the air”, which was how “most viruses” were transmitted, because they were too loose, had no air filter and left the eyes exposed.

Where they work is they help you avoid touching your eyes and nose unnecessarily: preventing “Ownself infect ownself”.

Remember that viruses can land on yr hands but they only cause problems when they enter yr body. Likely entry points are the mouth and eyes. The ears and nose have hair filters.

After reading the BBC article in above link especially this bit

The NHS says the best way to avoid catching viruses such as flu is to:

  • regularly wash your hands with warm water and soap
  • avoid touching your eyes and nose wherever possible
  • maintain a fit and healthy lifestyle

I came to the conclusion that they help prevent “Ownself infect ownself”.
