In some countries people wear masks when they have any respiratory diseases and do not touch the strangers they are greeting, which seems sensible. Otherwise, it depends on the parameters of the diseases you are trying to stay safe against. The thing about the flu is that you develop symptoms earlier, so the window of oportunity for unknowing transmission is shorter (on average). From what we know at this time, it's a less deadly disease than COVID-19. And it mutates quickly, with each season bringing new strains. I think if it was possible to erradicate it completely through vaccination that would be something worth considering, too. Nobody likes that it exists. https://www.cdc.gov/flu/symptoms/flu-vs-covid19.htm https://www.cdc.gov/flu/symptoms/flu-vs-covid19.htm https://bgr.com/2020/10/21/coronavirus-death-rate-vs-flu-cdc-study/ https://bgr.com/2020/10/21/coronavirus-death-rate-vs-flu-cdc...
