Seems like we are living through what would happen if the 1918 Spanish Flu meets 2020 modern medicine / epidemiology. I can't help but be optimistic that this problem will be solved. Here is another study on the way:

""The virus can't live by itself, right? It needs our genes and proteins in order to live and to replicate." Camostat mesylate is one of several candidate drugs that block those interactions. They don't target the virus, but us, the host."
"First, a protein on the viral surface called the spike attaches to a receptor on the human cell called ACE2. Then, another human protein, TMPRSS2, cleaves the spike protein, allowing the virus to fuse with the cell and start to replicate inside it. Camostat mesylate blocks TMPRSS2; in the Cell paper, molecular biologist Stefan Phlmann of the German Primate Center and other researchers showed the drug kept SARS-CoV-2 from infecting lung cells in the lab."
