Dr Jake Dunning, head of emerging infections and zoonoses [infectious disease spread between humans and animals] at Public Health England, told The Independent that there is “very little evidence of a widespread benefit” in members of the public wearing masks.
Dr Dunning explains there are a number of reasons why they aren’t effective. “Face masks must be worn correctly, changed frequently, removed properly, disposed of safely and used in combination with good universal hygiene behaviour in order for them to be effective.”
And most of the paper options being worn do not have a respirator to filter out infectious air particles.
If they are not worn properly and are loose fitting it means that bacteria can easily access the nose and mouth. Experts have also warned coronavirus could enter the body through the eyes.
Even when users do comply with these rules initially, research shows if users wear them for long periods of time they gradually become slack and are less likely to do so.
