WHO 6/8/20: "The widespread use of masks by healthy people in the community setting is not yet supported by high quality or direct scientific evidence"
Below are the key excerpts and links.
They also released some new videos including this one, which directly contradicts their previous videos, which are below:
The exact same woman a short time ago said "You do not need to wear a mask. Masks alone can give you a false feeling of protection and can even be a source of infection." Watch it here:
Another recent WHO video said: "If you have cough, fever and difficulty breathing, you should wear a mask and seek medical care. If you do not have these symptoms, you do not have to wear masks, because there is no evidence that they protect people who are not sick."
Page1 of WHO PDF dated 6/5/20:
Background- The use of masks is part of a comprehensive package of the prevention and control measures that can limit the spread of certain respiratory viral diseases, including COVID-19. Masks can be used either for protection of healthy persons (worn to protect oneself when in contact with an infected individual) or for source control (worn by an infected individual to prevent onward transmission). However, the use of a mask alone is insufficient to provide an adequate level of protection or source control, and other personal and community level measures should also be adopted to suppress transmission of respiratory viruses.
Whether or not masks are used, compliance with hand hygiene, physical distancing and other infection prevention and control (IPC) measures are critical to prevent human-to- human transmission of COVID-19.
[Page 6:] Advice to decision makers on the use of masks for the general public:
Many countries have recommended the use of fabric masks/face coverings for the general public. At the present time, the widespread use of masks by healthy people in the community setting is not yet supported by high quality or direct scientific evidence and there are potential benefits and harms to consider (see below).
Coronavirus disease (COVID-19) advice for the public: When and how to use masks 6/8/20
https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public/when-and-how-to-use-masks Footnote #73 in who PDF dated 6/5/20 states "Medical masks, general masks, and handkerchiefs were found to provide little protection against respiratory aerosols."
[Comparison of Filtration Efficiency and Pressure Drop in Anti-Yellow Sand Masks, Quarantine Masks, Medical Masks, General Masks, and Handkerchiefs
The aims of this study were to evaluate the filter efficiency of various mask types using the Korean Food and Drug Administration (KFDA) [similar to the European Union (EU) protocol] and the National Institute for Occupational Safety and Health (NIOSH) protocol and to compare the test results. We tested a total of 44 mask brands of four types (anti-yellow sand, medical, quarantine, general) and handkerchiefs with a TSI 8130 Automatic Filter Tester. A wide variation of penetration and pressure drops was observed by mask types....
