Measles is a viral disease.
Measles lives in the mucus of an affected person. It is highly contagious, enough so that "if one person has it, 90% of the people close to that person who are not immune will also become infected."
The symptoms of measles can appear anywhere from 7 to 14 days after a person is infected. It begins with high fever, cough, runny nose, affecting the respiratory system. A few days after symptoms begin, a rash breaks out. It usually starts as red spots on the face that then spread to the rest of the body. When this rash appears, a person's fever will spike. After a few days, the fever subsides and the rash fades, making the condition acute. For every 1,000 children who get measles, 1 or 2 will die from it.
"Measles can be prevented with MMR vaccine. CDC recommends children get two doses of MMR vaccine, starting with the first dose at 12 through 15 months of age, and the second dose at 4 through 6 years of age. Teens and adults should also be up to date on their MMR vaccination."
In 2016, 70 people from 16 states were reported to have measles. The majority of people who get measles are unvaccinated. Measles is still common in many parts of the world including some countries in Europe, Asia, the Pacific, and Africa.
