someone should tell this to the butcher as he swans around hospitals
Although I agree with the findings re masks, the Guardian Headline is misleading. Masks will not cut infection rates by 53%. The actual research doesn’t say that. The Guardian, once again has taken research out of context. Masks are a useful and effective barrier for all respiratory disease including flu and covid. The single most effective way is to ensure you have up to date vaccine.
