I wonder how much home pneumonia treatment options like humidifiers, steam, and drinking tons of fluids can impact the hospitalization rate? Quitting/taking a break from smoking has to be a big one too. Can we find ways to encourage more people to do these things, like some kind of viral science-based "Lower Your Covid Risk" website or app? It could promote social distancing too. One of the biggest problems so far imo is lack of clear, unambiguous guidance from authority figures. People in the general population still have wildly misinformed views. Finding creative ways to inject this kind of crucial information into the collective consciousness could have a big impact.
