Why the US has had so much trouble containing COVID-19

This study tells you a lot about why it’s so hard to contain COVID-19 unless everyone chips in.

A 13-year-old girl with COVID-19 infected 11 relatives during a three-week family gathering this summer , a spread that extended over 4 states.

Way way way too many people – including kids! – can pass this infection on to others without getting very sick – or even slightly sick – themselves.

Wear your masks – please!
