We study pandemics, and the resurgence of measles is a grim sign of what’s coming - Ars Technica

Analysts warn that the U.S. resurgence of measles—once declared eliminated—is a troubling sign tied to persistent immunity gaps. The South Carolina outbreak, the largest in decades, is a concrete example of that vulnerability and has now been declared over. Early indications that the outbreak prompted increased vaccinations offer a possible path to closing immunity gaps, but uneven coverage still leaves the country at risk for future resurgences.
