dumb question...…. if chloroquine is so hard to get now, why not just use quinine? It is readily available.
If you do any self medication first take a sheet of paper and a pencil, exactly write down what you did take and store it a highly visible point!
There is a long road, which will end with a vaccine.
That's dreaming of an UFO that will save the world...
That is, 12% of the adult population that is infected, not the whole population. I think this would be enough to push mortality significantly above the expected rate of ~2% or 3% for untreated patients in a catastrophic situation. Even if hospitals are not overwhelmed, there is no doubt that the 40% obese population will die at a higher rate than the average Japanese or Korean population, because obesity is rare in these countries. What it boils down to is that 40% of our population will die at the rate 70-year-old Japanese patients do, because we have a gigantic burden of comorbidity.
America is not a homogenous country. On the country side you can easily do a lockout for 6-8 weeks but in larger cities where people are used to buy their stuff almost on a daily basis the mess will start immediately after the lockdown will be announced. 10% of the people will buy 90% of the food and goods. Some people will have no food for at least 3 days and walk around like mad.
America is not an advanced civilization as the rich believe, In reality it's world ranked 30 or even behind in most things that are important to deal with modern threats. I expect hat the US will end much worse than Italy simply because nobody will care about the 70'000'000 people without healthcare, that will loose their jobs first and stay on the street with no money because the can no longer pay the rent.
All countries (like Germany, France, eastern Europe ) with a socialist background will perform much better as the sense for human behavior has been lived now for almost 100 years. USA mentally still lives in the Wild West where money is power and keeps you alive - most of the time...
