Did you read the paper I linked? Read it, and then tell me what the facts are. Whether or not they are offering advice based on facts or political considerations is a matter of debate. There is no real meaningful debate on the mechanisms of influenza transmission. 1 mechanism is decidedly airborne. How else can you reasonably explain infection rates? Hundreds of thousands of people are letting other people sneeze directly on them? The literature is clear about this, frankly I have no idea what the WHO is smoking.
