I don't believe the WHO because they are one of the notorious agenda driven agencies that wouldn't know the truth if it bit them.You believe the WHO, CDC and Imperial College London are all being driven by social media?
I take the CDC with a grain of salt because like other government agencies they tend to have agendas like the Surgeon General and his manipulative lies.
No clue about the Imperial College...
In short, I'll take what they say as something to consider, but only after I've looked at the data behind what they are saying... but I wouldn't just accept anything they say on its face.
