I'm not a statistician or a scientist, but I don't it does any good to lump everything together over the past ~9 months and compare it to Influenza and Pneumonia. Just think about it. We barely knew anything about covid or how to treat it at the start of the year. Now, it seems like we have a better understanding and how to potentially treat it. Compare this to Influenza/Pneumonia, which I'm just guessing we've been…
Do we? It's mostly the same symptomatic treatment afaik, influenza antivirals are barely effective. The real difference is that there is a vaccine.
