> Here you need to remember that the W stands for "World". So they give dubious advice to the entire world since the good advice doesn't perfectly fit the world in entirety? There are many better options: don't give advice, explain two sets of advice, ask for advice from governments to be followed, make the advice generic enough that it still applies to the world. An example of advice that might apply anywhere in the world: "Face coverings will help to reduce transmission. In most parts of the world, masks will be in short supply and needed by health care workers much more than the general population. Masks can be made from any type of cloth. Although these may not have the same efficacy as high grade masks and the efficacy will be dependent upon the material used as well as the degree of seal against the face, these will help to reduce transmission."
