If you know you have the flu (or COVID-19), surely you know you are likely contagious and can spread it to more vulnerable people. Yes, it is your fault and you deserve blame if you knowingly spread it to others through negligence. Stay home if you're sick.

I agree those who are symptomatic should stay home. But for COVID we go further and tell asymptomatic people to perform (flawed) transmission control measures. Where do we do that with Flu?

The point is if I don’t know I have COVID and spread it to Grandma at the grocery store, in your eyes I’ve killed Grandma. I wonder why we don’t apply that logic everywhere.

The influenza vaccine is a flawed transmission control measure and is the best we have available, same as masks. We do blame people who skip those, although it doesn't show on their faces like the absence of a mask does.

The spreadability of the flu is also much lower than that of COVID-19 (largely thanks to the vaccines), which is really why people never regarded masks as necessary for the flu.
