The U.S. is experiencing a significant surge in measles cases, with reports indicating over 300 total infections across 15 states, marking the highest number since a record wave in 2019. Texas is at the forefront of this outbreak, witnessing a rise to 259 cases, primarily affecting children and teens but with only a small fraction among fully vaccinated individuals. Health officials, including those in the Bay Area, are urging vaccination as a key protective measure against the outbreak. Experts warn that the actual number of cases could be larger than reported, and there are growing concerns in areas such as West Texas and even reaching toward Ohio. As vaccination efforts ramp up, discussions about the necessity of measles immunization in schools and among the public continue to intensify.
