For Everyone Else

In a Channel 4 clip, Hugh Montgomery does some back-of-the-napkin math contrasting the normal flu against the coronavirus.

“If you are irresponsible enough to think that you don’t mind if you get the flu, remember it’s not about you – it’s about everybody else.”

Montgomery assumes that on average, someone infected by the coronavirus infects 3 others and that someone with the normal flu infects 1.3 to 1.4 others. There’s still more to find out about that 3x figure, but the main point — that staying at home right now is for the good of everyone — still holds.
