The history of epidemics is rife with examples of society rebelling against tough public-health edicts, such as the breach of plague quarantine in 18th-century Marseille or protests against face masks during the 1918 influenza pandemic. The grim consequence is a fresh wave of deadly infections.

COVID-19’s million deaths may pale in comparison to the estimated 50 million lives lost in 1918, but the cycle risks unfolding again. France, the U.K. and Spain face a triple threat: A jump in cases, a population exhausted by lockdown-induced recession, and rising resistance to tougher measures.

Curfews and closures of restaurants and bars have seen business owners literally throw their keys to the ground in present-day Marseille. In Madrid, protesters have bristled at a targeted local lockdown they view as discriminatory. It’s not just conspiracy theorists on the streets in London and Berlin who are angry.
