CNN —The number of measles cases around the world nearly doubled from 2022 to 2023, researchers say, presenting a challenge to efforts to achieve and maintain elimination status in many countries. The US has had 128 measles cases reported in 20 jurisdictions this year, as of Friday, according to the US Centers for Disease Control and Prevention. Measles was declared eliminated in the US in 2000, “meaning there is no measles spreading within the country and new cases are only found when someone contracts measles abroad and returns,” the CDC says. However, the rapid rise in cases this year poses a threat to that disease elimination status, the agency says.
