The Centers for Disease Control and Prevention reported more than 5,000 confirmed measles cases nationwide, the highest tally in 35 years and a sharp reversal of the country's 2000 elimination status. According to the agency's latest surveillance data, children and teenagers account for almost 60 percent of all confirmed infections, with the majority of cases concentrated in under-vaccinated communities across several states. Health officials said the outbreak has strained local public health resources and prompted renewed calls for expanded immunization outreach.
CDC officials attributed the surge to declining vaccination coverage and increased international travel introducing the virus into susceptible populations. The agency urged parents to verify their children's measles-mumps-rubella vaccination status and advised clinicians to remain vigilant for symptoms, including fever, cough, and rash. Public health experts noted that measles is among the most contagious known viruses and can cause severe complications, particularly in young children. State health departments in affected regions have launched targeted vaccination clinics, while federal officials said they are coordinating with local authorities to contain further spread. The CDC is expected to publish updated guidance as the investigation continues.
