Why measles is the master childhood infection
By Michael Mina
Measles was once so common it was considered a near right-of-passage into adulthood. Until the introduction of the measles containing vaccine in the 1960’s, the measles virus, arguably the most transmissible pathogen to infect humans, infected nearly 100% of children. Today, approximately 7 million cases continue to occur annually, or about 5% of the annual global birth cohort, reflecting a massive reduction in expected measles incidence of approximately 95%.
