" The WHO-commissioned meta-study on the effectiveness of facemasks, published in the medical journal The Lancet in June 2020, has been instrumental in shifting global facemask policies during the Covid-19 pandemic. However, the meta-study, which claimed a risk reduction of 80% with facemasks, is seriously flawed on several levels and should be retracted"

Op 03.05.2009 ( ! ) heeft de WHO een rapport gepubliceerd waarin zij het gebruik van mondmaskers in het kader van de Mexicaanse INFLUENZA epidemie ... af raadde en zelf aangaf dat niet aangetoond is dat dat het dragen van mondmaskers voordelen oplevert.
"The benefits of wearing masks has not been established, especially in open areas, as opposed to enclosed spaces while in close contact with a person with influenza-like symptoms. Nonetheless, many individuals may wish to wear masks in the home or community setting, particularly if they are in close contact with a person with influenza-like symptoms, for example while providing care to family members.
Furthermore, using a mask can enable an individual with influenza-like symptoms to cover their mouth and nose to help contain respiratory droplets, a measure that is part of cough etiquette.
"Using a mask incorrectly however, may actually increase the risk of transmission, rather than reduce it. If masks are to be used, this measure should be combined with other general measures to help prevent the human-to-human transmission of influenza, training on the correct use of masks and consideration of cultural and personal values. https://www.who.int/.../Adviceusemaskscommunityrevised...
