Los Angeles County has become one of the most closely watched epicenters of the national measles outbreak — and for heartbreaking reason. Public health officials confirmed earlier this year that a child in Los Angeles County died from a measles-related complication, becoming one of only four measles-associated deaths recorded in the United States during the current outbreak cycle. The death sent a chilling signal through a city that has long prided itself on strict school vaccination requirements and high overall immunization coverage.
