Measles is one of the most highly contagious diseases, but is preventable through vaccination. The measles virus is spread through coughing and sneezing. Before widespread use of measles vaccines there was an average of half a million measles cases and hundreds of deaths each year in the United States.
Measles is common in many parts of the world, including both industrialized and developing countries. Local cases of measles are often linked to travel or exposure to recent travelers. Worldwide, more than 20 million people are infected each year. Measles is the leading cause of vaccine-preventable death among children in the world.
