Advocates of government edicts have asserted that these would bring the pandemic “under control” in a matter of weeks. The authors of this Backgrounder found that 97 of the 100 counties with the most confirmed cases had mask mandates. Nor did a national mask mandate prevent a surge in Italy. These findings do not deny the efficacy of mask-wearing, nor should they discourage the practice. Instead, they point to the inadequacy of public health strategies that rely too heavily on lockdowns and mask mandates. Governments should undertake more effective interventions, such as specifically protecting nursing home residents, enabling nationwide screening through use of rapid self-tests, and establishing voluntary isolation centers where infected people can recover, rather than exposing their families to infection.
