For people living in the US, at what point does it become particularly important to start following these methods? I assume it’s always beneficial, but risk adjusted not particularly important until there start being more cases in the US or until we start having more cases. Is that assumption right or dangerously wrong?
There doesn’t seem to be any local transmission in the US yet—so for now, I guess it probably wouldn’t help much (though it would still help prevent the spread of the common cold/flu!).
If/when there is local transmission, following this advice will be very important.
