Why did WHO say Sweden is the model?
Joe provided half the story, whether intentionally or due to lack of comprehension, or failure to dive beyond the headlines I can't say...
Anyway, what the WHO is saying is that IF we are to escape lockdown, Sweden is the model because they have managed to (semi) successfully rely on a combination of enhanced social responsibility AND a comprehensive public health policy including thorough testing, etc.
What The WHO is pointedly NOT saying is that the Swedish model is inherently superior or is "working better." But you'll miss those subtleties if you rely on nothing but headlines and preconceived opinion.
