When was the first measles epidemic?
Measles was first reported in the United States in 1765, eventually killing about 6,000 people a year in the early 20th century. The creation and licensure of the measles vaccine in 1963, followed by widespread vaccination, led to the elimination of measles in the United States in 2000.
Is measles a man made virus?
Like many human diseases, measles originated in animals. A spill-over of a cattle-infecting virus, the common ancestor to both measles virus and its closest relative rinderpest virus is understood as likely to have given rise to the disease.
How did the measles outbreak stop?
Measles was declared eliminated from the United States in 2000 by the World Health Organization due to the success of vaccination efforts. However, it continues to be reintroduced by international travelers, and in recent years, anti-vaccination sentiment has allowed for the reemergence of measles outbreaks.

What did measles evolve from?
Measles, caused by measles virus (MeV), is a common infection in children. MeV is a member of the genus Morbillivirus and is most closely related to rinderpest virus (RPV), which is a pathogen of cattle. MeV is thought to have evolved in an environment where cattle and humans lived in close proximity.
Is measles a natural virus?
Measles is an acute viral respiratory illness caused by a single-stranded, enveloped RNA virus with a single serotype (genus Morbillivirus, family Paramyxoviridae). Humans are the only natural host of measles virus. Patients are considered to be contagious between 4 days before and 4 days after the rash appears.
