Measles cases in the U.S. are at their highest in three decades. The U.S. Centers for Disease Control and Prevention says the U.S. has 1,288 cases since the beginning of the year. That’s higher than 2019, when there 1,274 cases driven by 22 outbreaks over 12 months. Seventeen states have seen outbreaks this year. Experts fear the U.S. may lose its status as having eliminated measles. There are also large outbreaks of the vaccine-preventable disease in Mexico and Canada.
