Abstract
Measles, mumps, and rubella have impacted millions of American lives over the last 100 years. During the last century, researchers have identified viral diseases, developed a combination vaccine, and have continued ongoing research when outbreaks have occurred. Despite the high incidence of vaccinated individuals, these highly communicable diseases continue to flourish within clusters of outbreaks throughout the United States. Emergency medicine providers play a key role in early recognition and diagnosis of the disease. The proper management and reporting reflect the emphasis on prevention of widespread outbreaks.
