Measles virus. Coloured transmission electron micrograph (TEM) of a measles virus (rubeola),with its envelope broken exposing the nucleocapsid filaments. Nucleocapsids are protein-nucleic acid complexes that are normally coiled up into a ball,which contain the genetic material of the virus. Measles viruses are morbilliviruses,a type of paramyxovirus. Measles is highly infectious and mainly affects children,producing fever and a rash. One attack usually provides lifelong immunity | |
