Wearing a face mask does help reduce the risk of transmitting COVID-19, according to a major UK study, that found that specialized N95 types or two surgical masks worn together were likely to have the greatest effect.
In contrast to some European neighbors, the British government has lifted all requirements for wearing face coverings, although businesses and transport companies are able to make their own rules.
