I agree 1% high, and I wish it were lower. On the other hand, weโre specifically targeting stealth pathogens: ones where any distinctive symptoms come well after someone becomes contagious. Absent a monitoring system, you could be in a situation most people had been infected before anyone noticed there was something spreading. Flagging this sort of pathogen at 1% cumulative incidence still gives some time for rapid mitigations, though itโs definitely too late to nip it in the bud.
