You're all for shutting down the economy for a virus of marginal danger, but can't see why we should change our way of life for an extinction level danger. This virus has been overblown. SARS was a completely different matter. This is not an emergency and we shouldn't be treating it as such.
There's lots of reports that the major airports aren't doing proper screening or often any screening of passengers on planes coming from China. Screening doesn't reduce economic activity, it's just being proactive.
The sky isn't falling but we should take it seriously if the WHO is saying it's "a global health emergency of international concern".
