Quick fact check: first of all, 3 deaths out of 750 isn't relevant without knowing the timeline of transmission, as most deaths occur 3-4 weeks post infection.

Second, there have deaths of people in there 20's a casual google search of 'youngest death coronavirus' yields that information as the first result.

And if you believe every young death (or every death) in Hubei province is being publicized, you haven't been paying attention.

I do agree that it's important not to panic, but we absolutely should be taking social distancing measures to reduce the r0.
