Face coverings became mandatory in UK shops and supermarkets from 24 July 2020. They were commonly worn for indoor public settings and sometimes outdoors too.
Following this guidance, the wearing of masks was adopted to varying degrees by the British public and some people will also wear a mask outdoors or in cars.
More than 150 Comparative Studies and Articles on Mask Ineffectiveness and Harms
Brownstone Institute, Paul Elias Alexander
It is not unreasonable to conclude that surgical and cloth masks, used as they currently are being used (without other forms of PPE protection), have no impact on controlling the transmission of Covid-19 virus. Current evidence implies that face masks can be actually harmful. The body of evidence indicates that face masks are largely ineffective.
My focus is on COVID face masks and the prevailing science that we have had for nearly 20 months. Yet I wish to address this mask topic at a 50,000-foot level on the lockdown restrictive policies in general. I build on the backs of the fine work done by Gupta, Kulldorff, and Bhattacharya on the Great Barrington Declaration (GBD) and similar impetus by Dr. Scott Atlas (advisor to POTUS Trump) who, like myself, was a strong proponent for a focused type of protection that was based on an age-risk stratified approach.
Face masks in the COVID-19 era: A health hypothesis
An official Stanford University facemask study published in the US National Library of Medicine
Many countries across the globe utilised medical and non-medical face masks as non-pharmaceutical intervention for reducing the transmission and infectivity of coronavirus disease-2019 (COVID-19). Although, scientific evidence supporting face masks’ efficacy is lacking, adverse physiological, psychological and health effects are established. Is has been hypothesised that face masks have compromised safety and efficacy profile and should be avoided from use. The current article comprehensively summarises scientific evidences with respect to wearing face masks in the COVID-19 era, providing prosper information for public health and decision making.
