Most communicable of all contagious diseases is measles. It spreads much faster than its nearest morbid rivals, smallpox and influenza. And it infects practically every person exposed to it, unless he has been immunized by an attack of the disease. In this country next winter and spring some 800,000 people, chiefly children, will catch measles. Only a few will die, and those the victims chiefly of broncho-pneumonia which often accompanies a measles attack. But many will suffer the rest of their lives from poor hearing which measles often initiates.
