From Wiki:
Measles, also known as morbilli, English measles, or rubeola (and not to be confused with rubella or roseola) is a highly contagious viral infection of the respiratory system, immune system, and skin caused by a paramyxovirus of the genus Morbillivirus.[1][2] Symptoms usually develop 7–14 days (average 10–12) after exposure to an infected person and the initial symptoms usually include a high fever (often > 40 °C [104 °F]), Koplik’s spots (spots in the mouth, these usually appear 1–2 days prior to the rash and last 3–5 days), malaise, loss of appetite, hacking cough (although this may be the last symptom to appear), runny nose and red eyes.[1][3] After this comes a spot-like rash that covers much of the body.[1] The course of measles, provided there are no complications, such as bacterial infections, usually lasts about 7–10 days.[1]
Measles is an airborne disease that is spread through respiration (contact with fluids from an infected person’s nose and mouth, either directly or through aerosol transmission via coughing or sneezing). The virus is highly contagious—90% of people without immunity sharing living space with an infected person will catch it.[4] An asymptomatic incubation period occurs nine to twelve days from initial exposure.[5] The period of infectivity has not been definitively established, some saying it lasts from two to four days prior, until two to five days following the onset of the rash (i.e., four to nine days infectivity in total),[6] whereas others say it lasts from two to four days prior until the complete disappearance of the rash. The rash usually appears between two and three days after the onset of illness.[7]
