Omicron appears to be in retreat, even if the official national data doesn’t yet reflect that reality. Omicron also appears to be mild in a vast majority of cases, especially for the vaccinated. This combination means that the U.S. may be only a few weeks away from the most encouraging Covid situation since early last summer, before the Delta variant emerged.

If that happens — and there is no guarantee it will, as Katherine Wu of The Atlantic explains — it will be time to ask how society can move back toward normalcy and reduce the harsh toll that pandemic isolation has inflicted, particularly on children and disproportionately on low-income children.

When should schools resume all activities? When should offices reopen? When should masks come off? When should asymptomatic people stop interrupting their lives because of a Covid exposure? Above all, when does Covid prevention do more harm — to physical and mental health — than good?
