What type of virus is rubeola?

Measles is caused by Rubeola virus, which belongs to the Paramyxovirus family. Measles is an acute systemic viral infection with fever, respiratory involvement and symptoms, and a rash. Measles can cause serious complications and even fatalities. Infection confers lifelong immunity.
