Whoa, crossing into personal attack and flamewar comments like you did here, and elsewhere in this thread, is totally not cool on HN, no matter how wrong someone else is or you feel they are.

We ban accounts that post like this, because it's so destructive of the community we're trying to have here. If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and sticking to the rules, we'd be grateful.

Flu is an influenza virus not a coronavirus - it's literally in the name.

Additionally, varying levels of contagiousness and mechanisms of spread absolutely make actions more effective for some diseases and less effective or not effective at all for others. This is not a controversial statement despite your dramatic insistence on ignorance.

Similar sized virus, respiratory and seasonal. Plenty of similarities.

The median R value for seasonal influenza(aka flu) was 1.28 (IQR: 1.19–1.37), whereas the R rate for COVID without any protection is much higher. It means people staying at home, reducing visits and social distancing might be enough to lower the R rate below one for influenza, however, not necessarily for COVID as the R rate is higher.

R-factor.

If 90%* wear masks and the R-factor of the "flu" is is low enough it "disappears". But if the R-factor for covid is high enough it still spreads even if 90%* wear masks (10% don't).

It's mindboggling how simple simple thinking can evade people.

Influenza is not a coronavirus

Flu is not a coronavirus but a completely different one. Different viruses behave differently. How hard is that to rationalize?

Influenza is not a coronavirus.

Please don't feed flamewars on HN. We're trying for the opposite here.
