The U.S. is experiencing a dramatic surge in measles cases, reaching a 35-year high with over 2,300 reported cases this year alone. This alarming rise marks the second consecutive record-breaking year for the disease, driven by declining vaccination rates. Health officials are warning that the resurgence threatens to undermine decades of progress toward measles elimination, as certain states, including Florida and California, report significant spikes. Experts are urging communities to increase vaccination efforts to combat this highly contagious virus and protect vulnerable populations.
