US measles outbreak: 3,000+ cases, 4 deaths, worst since 1991

A measles epidemic in the US has caused over 3,000 cases and four deaths, the largest outbreak since 1991, in a disease declared eliminated in 2000. The resurgence is attributed to declining vaccination rates and growing mistrust of health authorities. This marks a significant reversal of a previously eliminated disease, signaling a public-health crisis with potential for further spread.
