Opinion: How measles reemerged as a threat in California and elsewhere
LA TimesThe measles virus is resurging in the U.S. despite the long-standing availability of a vaccine that provides nearly life-long immunity. In the past few weeks, hundreds of people were exposed to a child with the virus in a Northern California healthcare facility; our state is one of 17 jurisdictions with reported measles cases in 2024, higher than seen in recent years. Before the measles vaccine was introduced and licensed in 1963, the Centers for Disease Control and Prevention cites an annual average of 549,000 cases, 48,000 hospitalizations, nearly 500 deaths and 1,000 people with chronic disability. But a recent nationwide survey found that Southern California alone has 350 schools falling short of the desired vaccination threshold, meaning a single measles case in these schools could easily become an outbreak among the unvaccinated. Marin County had among the lowest measles vaccination rates in the state in 2011 and now has coverage close to 99% among children entering school.
