Measles

Measles (sometimes known as English 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 living space with an infected person will catch it. The infection has an average incubation period of 14 days (range 6–19 days) and infectivity lasts from 2–4 days prior, until 2–5 days following the onset of the rash (i.e. 4–9 days infectivity in total).
 * Measles**, also known as **rubeola** or **morbilli**, is an infection of the respiratory system caused by a virus, specifically a paramyxovirus of the genus //Morbillivirus//. Morbilliviruses, like other paramyxoviruses, are enveloped, single-stranded, negative-sense RNA viruses. Symptoms include fever, cough, runny nose, red eyes and a generalized, maculopapular, erythematous rash.



Complications with measles are relatively common, ranging from relatively mild and less serious diarrhea to pnemounia and acute encephalitis (and rarely subacute sclerosing panencephalitis; corneal ulceration leading to corneal scarring. Complications are usually more severe amongst adults who catch the virus.
