Measles virus

Ultrastructural appearance of a single virion of the measles virus, transmission electron microscopy (TEM). The virus is 100-200 nm in diameter, with a core of single-stranded RNA. It causes measles, an infection of the respiratory system. It is very contagious and is spread by coughing, sneezing and close personal contact or contact with infected fluids. Symptoms may include fever, runny nose, cough, red eyes and a generalized rash. Prior to 1963, almost everyone got measles. However, after vaccination became available for the disease, the number of cases dropped by 98 %. Image courtesy of the Centers for Disease Control and Prevention (CDC / Cynthia S.
