Best case scenario of all these response measures would be stretching out cases over time so that the healthcare system can manage the load. And, if a vaccine can be successfully developed in time, the outbreak may have only one peak. However, there may be a risk that after several months of the new reality, people get complacent, stop washing hands, start gathering in large groups again, etc.; and if the virus is still active, the virus might then infect everyone even worse in a second outbreak. I hope to see some discussion about such a possibility.
