California probably has a month tops, nobody is going to accept completely halting their lives for two months let alone anything longer.
There will be overlap between people who die of diseases routinely (the elderly, the immuno-compromised, and those with underlying conditions, and the unlucky) and those who die of this disease. No matter, the point still stands - if 100,000 people dying is what it takes to change people's behaviour significantly, that ought to happen every month, and it doesn't.
The death rate among the under-70 population is a different matter. If the medical system is overloaded and working-age people start dying en masse, I imagine that would change public consciousness quickly.
