I see your point. But we're exposed to many risks in this fragile, densely populated metropolis, including flu epidemics, traffic accidents, terrorism, typhoons, earthquakes, and tsunamis, that we could avoid by staying home or living elsewhere. Once we have made the decision to keep living here, I guess many of us also decide to go on with our lives as best we can.

Has there been any concrete evidence of asymptomatic spread? Also from start I know most Pele fall in the 5 days range for showing symptoms. I think you'll find out much sooner if there is community spread. In Singapore they've done an amazing job at contact tracking and nearly all the cases are in distinct related clusters.
