From January 1, 2020, through March 28, 2024, there were 338 confirmed measles cases, 29% of which occurred during the first quarter of 2024, according to Centers for Disease Control and Prevention’s (CDC’s) recent report. Researchers note that almost all cases reported in 2024 occurred in people who were unvaccinated or whose vaccination status was unknown. The study is subject to some limitations such as underreported cases of measles resulting from exposure outside of the United States and discarded cases after investigation. According to CDC, the risk of widespread measles transmission remains low in the US; however, the agency encourages routine measles, mumps, and rubella vaccination coverage and vaccination before international travel.
