The United States is currently experiencing its worst year for measles in over three decades, as reported cases surge to the highest levels since the disease was declared eliminated in 2000. The CDC has documented a staggering 1,288 cases, marking the highest annual tally in 33 years. Outbreaks have spread across various states, including Missouri and Wisconsin, prompting health officials to urge vaccination in light of significant sliding vaccine rates. Concerns are growing as the U.S. faces the largest measles outbreak in more than 30 years, with cases surpassing numbers recorded in 2019 and approaching a 25-year high.
