[More than 4,000 confirmed cases of measles in the United States this year] October 31, the latest data released by the US Centers for Disease Control and Prevention on October 30 showed that as of October 29, the cumulative number of confirmed cases had reached 4,852, more than double the total number of cases in 2025 of 2,289. About 96% of confirmed cases have not been vaccinated against measles or their vaccination status is unknown. U.S. media quoted expert opinions as reporting that the rebound in measles epidemics reflects the serious challenges faced by the U.S. public health system, including declining vaccination rates and declining public trust in health institutions. These problems may cause the United States to face greater difficulties in responding to future infectious disease threats. (CCTV International News)
