Yes, that's exactly right, but 3 months (or even 1 month) may be enough time to prevent unnecessary deaths by preparing hospitals, getting more ventilators, rolling out testing, and hopefully finding a therapeutic drug (vaccines are probably farther off).
Hey - owner of the model in question here. The idea here is to buy time; time to roll out testing (so only those that test positive need to isolate), prepare beds and ventilators, and develop therapeutics (vaccines are likely quite a bit farther off).
Hey guys - owner of the model in question here. Thanks for your feedback, and yes, the model isn't perfect. Idea is just to give some forward-looking picture for policy-makers to use to make decision.
Interestingly, the model is not nearly as sensitive to R-values as you would think, until they get under 1.5 (half the current observed number in most places).
