Overview
Background
Measles, also known as rubeola, is a disease caused by a virus , specifically a paramyxovirus of the genus Morbillivirus.
Reports of measles go as far back to at least 600 B.C. however, the first scientific description of the disease and its distinction from smallpox is attributed to the Persian physician Ibn Razi (Rhazes) 860-932 who published a book entitled "Smallpox and Measles" (in Arabic: Kitab fi al-jadari wa-al-hasbah). In 1954, the virus causing the disease was isolated from an 11-year old boy from the US, David Edmonston, and adapted and propagated on chick embryo tissue culture.[1] To date, 21 strains of the measles virus have been identified.[2] Licensed vaccines to prevent the disease became available in 1963.
Measles is spread through respiration (contact with fluids from an infected person's nose and mouth, either directly or through aerosol transmission), and is highly contagious—90% of people without immunity sharing a house with an infected person will catch it. Airborne precautions should be taken for all suspected cases of measles.
The incubation period usually lasts for 4–12 days (during which there are no symptoms).
Infected people remain contagious from the appearance of the first symptoms until 3–5 days after the rash appears.
German measles is an unrelated condition caused by the rubella virus.
