Measles is a very contagious disease caused by a virus that lives in the nose and throat of an infected person.
The virus is released when an infected person breathes or coughs. It spreads easily from person to person through the air or by direct contact with nose or throat discharges from someone who is infected. Measles symptoms include fever and a rash that starts on the face at the hairline and spreads to the neck, trunk, arms, legs, and feet. A cough, runny nose, or red, itchy eyes might also be present. Symptoms usually begin 7–14 days after exposure, but can appear up to 21 days after exposure. Measles is a serious illness that can cause complications that lead to hospitalization and even death.

Measles is easily preventable.
A safe and effective vaccine that prevents measles is given as part of the measles, mumps and rubella (MMR) vaccine or the measles, mumps, rubella, and varicella (MMRV) vaccine series. Since measles-containing vaccines became available in the United States, the disease has become rare in this country. Two doses of the vaccine are given to provide lifetime protection. The first dose is given at age 12-15 months and the second dose is given before kindergarten entry (age 4-6 years). Over 90% of the U.S. population is vaccinated against measles and approximately 95% of kindergarteners in Virginia are vaccinated against measles. However, infants younger than 12 months old are too young to be vaccinated. These infants and others who are not vaccinated are very susceptible to infection if they are exposed to someone with measles.
