The measles outbreak in the United States is severe.

Data released by the U.S. Centers for Disease Control and Prevention (CDC) shows that at least 910 confirmed cases of measles have been reported in the United States this year, five times the average annual number in the U.S. Moreover, most cases are concentrated in communities with insufficient or no vaccination. In recent years, the vaccination rate for measles, mumps, and rubella (MMR) among U.S. kindergarten children has been declining, undoubtedly providing fertile ground for measles transmission. For example, in some areas of Texas, vaccination rates are far below recommended levels, making these areas hotspots for the outbreak. The U.S. declared measles eradicated in 2000, and since then, an average of about 180 measles cases have been reported annually. However, in 2025, a large-scale measles outbreak occurred again, with more than 2,000 confirmed cases reported throughout the year, a new high since 1992. This outbreak has affected at least 43 states, covering a very wide area. Most confirmed patients were unvaccinated or had unclear vaccination status, which is closely related to the declining vaccination rate. Of the cases included in the national statistics, approximately 93% occurred among unvaccinated or unvaccinated individuals. The ongoing anti-vaccine movement and the spread of anti-vaccine rumors in the United States in recent years are significant contributing factors to the current pandemic. Influenced by these factors, many people have developed doubts about the safety, effectiveness, and necessity of vaccines, leading to a continued decline in vaccination rates. Furthermore, U.S. Health Secretary Robert Kennedy’s long-standing criticism of vaccines and medical institutions, along with some misleading statements, has undermined public confidence in the benefits of vaccines, threatened access to some vaccines, and further exacerbated the decline in vaccination rates. Measles is a highly contagious disease that can lead to serious complications such as pneumonia and encephalitis, and even death. This pandemic not only poses a serious threat to the health of the American public but may also cause the United States to lose its status as a country that has “eliminated measles.” Therefore, for your own health and the health of others, everyone should prioritize vaccination. If you have any questions, consult a professional doctor and do not blindly believe anti-vaccine claims.
