Question: Has WHO made a recommendation on using masks?

Answer passage (source: WHO):
page_title: Q&A: Masks and COVID-19
section_headers: What is WHO recommending to countries that are considering public mask use in community?
section_content: For countries that are currently considering the use of masks, WHO advises
decision makers to apply a risk-based approach and consider the following:
Purpose of mask use: if the intention is preventing the wearer
transmitting infection to others (that is source control) or to offer
protection to the wearer against infection (that is prevention).
Risk of exposure to COVID-19

due to epidemiology/number of cases in the population: if there is high community transmission and other measures such as contact tracing or ability to carry out testing are not possible. 
depending on occupation: e.g., individuals working in close contact with public (e.g., community health worker, cashier). 

Vulnerability of the mask wearer/population: for example, if supplies are
adequate medical masks could be used by people with comorbidities, such as
cardiovascular disease or diabetes mellitus, older people, immunocompromised
patients.
Setting in which the population lives: settings with high population
density (e.g. refugee camps, those living in cramped conditions) and settings
where individuals are unable to keep a safe distance (e.g. crowded buses or
other transport).
Feasibility: availability and costs of masks, access to clean water to
wash non-medical masks, and ability of mask wearers to tolerate adverse
effects of wearing a mask.
Type of mask: medical mask versus non-medical mask (prioritization of
medical masks for health care providers, symptomatic people and their
caregivers).
In addition to these factors, potential advantages of the use of masks by
healthy people in the community setting include reducing potential exposure
risk from an infected person during the ‘pre-symptomatic’ period or if an
infected person is asymptomatic.
There are potential risks and disadvantages that should be taken into account
in any decision-making process on the use of masks:

Non-medical or cloth masks could increase potential for COVID-19 to infect a person if the mask is contaminated by dirty hands and touched often, or kept on other parts of the face or head and then placed back over the mouth and nose 
Depending on the type of mask used, could cause difficulty in breathing 
They can lead to facial skin breakdown 
They can lead to difficulty with communicating clearly 
They can be uncomfortable to wear 
It is possible that mask use, with unclear benefits, could create a false sense of security in the wearer, leading to diminished practice of recognized beneficial preventive measures such as physical distancing and hand hygiene. 


Reviewer feedback on this answer:
This answer is excellent because it provides information directly from WHO about the different usages of face masks during the pandemic, which answers the question.
Way too much info presented, too easy to get bogged down in the slog trying to get through this only to find out it gives no actual recommendations.

Answer passage (source: WHO):
page_title: Q&A: Masks and COVID-19
section_headers: How did WHO reach its scientific conclusions on mask use?
section_content: WHO convenes global teams of experts that collectively review the latest
studies. Throughout the COVID-19 pandemic, a group of more than 80 experts in
infection prevention and control from institutions worldwide participate in
weekly advisory calls to help inform WHO guidance documents. Advice on mask
use for healthy individuals in community settings was developed in
consultation with several senior experts.

Reviewer feedback on this answer:
Dances all around the topic but never actually answers the question. Sounds like a politician wrote it.
This answer is bad because it doesn’t clarify much about what the WHO has said about properly using face masks during the pandemic.

Answer passage (source: WHO):
page_title: Q&A: Masks and COVID-19
section_headers: What is WHO’s view on masks?
section_content: WHO recognizes that there are many questions about the use of face masks to
prevent the transmission of COVID-19 in the community, and that many countries
are recommending that people wear them. Wearing a medical mask can limit the
spread of certain respiratory viral diseases, including COVID-19. However, the
use of a mask alone is not sufficient to provide an adequate level of
protection. Other measures such as physical distancing and hand hygiene should
be adopted.
WHO aims to provide the most scientifically sound yet practical
recommendations for the safety and wellbeing of individuals in all settings.
At present, WHO recommends a risk-based approach to be considered by decision
makers when deciding in which settings and circumstances non-medical masks
could be used in the community.

Reviewer feedback on this answer:
This answer is acceptable because it does answer the question regarding the WHO and face masks, but could use a little more detailed information about what exactly the WHO says about different types of face mask situations.
To the "average Joe" asking about WHO mask recommendations this is not very informational. Needs to include concrete recommendations.
