A red, flat rash which usually starts on the face and then spreads to the rest of the body typically begins three to five days after the start of symptoms.<ref name=CDC2014SS>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days.<ref name=WHO2014/><ref name=Conn2014>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref> Complications occur in about 30% and may include diarrhea, blindness, inflammation of the brain, and pneumonia among others.<ref name=WHO2014/><ref name=CDC2012Pink/> Rubella (German measles) and roseola are different diseases.<ref>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref>

Measles is an airborne disease which spreads easily through the coughs and sneezes of those infected. It may also be spread through contact with saliva or nasal secretions.<ref name=WHO2014/> Nine out of ten people who are not immune who share living space with an infected person will catch it. People are infectious to others from four days before to four days after the start of the rash.<ref name=CDC2012Pink>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref> People usually only get the disease at most once.<ref name=WHO2014/> Testing for the virus in suspected cases is important for public health efforts.<ref name=CDC2012Pink/>

The measles vaccine is effective at preventing the disease. Vaccination has resulted in a 75% decrease in deaths from measles between 2000 and 2013 with about 85% of children globally being currently vaccinated. No specific treatment is available. Supportive care may improve outcomes.<ref name=WHO2014/> This may include giving oral rehydration solution (slightly sweet and salty fluids), healthy food, and medications to control the fever.<ref name=WHO2014/><ref name=Conn2014/> Antibiotics may be used if a secondary bacterial infection such as pneumonia occurs. Vitamin A supplementation is also recommended in the developing world.<ref name=WHO2014>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Measles affects about 20 million people a year,<ref name=MM2014/> primarily in the developing areas of Africa and Asia.<ref name=WHO2014/> It causes the most vaccine-preventable deaths of any disease.<ref name=Kabra2013>{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref> It resulted in about 96,000 deaths in 2013, down from 545,000 deaths in 1990.<ref name=GDB2013>{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref> In 1980, the disease is estimated to have caused 2.6 million deaths per year.<ref name=WHO2014/> Before immunization in the United States between three and four million cases occurred each year.<ref name=CDC2012Pink/> Most of those who are infected and who die are less than five years old.<ref name=WHO2014/> The risk of death among those infected is usually 0.2%,<ref name=CDC2012Pink/> but may be up to 10% in those who have malnutrition.<ref name=WHO2014/> It is not believed to affect other animals.<ref name=WHO2014/>
