Measles symptoms: What to look for and how to protect yourself
Measles symptoms typically begin 10 -14 days after exposure and include a fever above 101°F, a runny nose, cough, and red, watery eyes. A red rash usually appears one to four days later, starting on the face and spreading to the rest of the body.
People who may have been exposed should monitor for symptoms for up to 21 days. If symptoms such as fever or rash develop, individuals should avoid public places, including schools and work, and contact their healthcare provider before visiting a doctor’s office or emergency room.
Health officials are particularly concerned about individuals who are at higher risk for complications from measles, including pregnant women, infants younger than 1 year old, and those with compromised immune systems.
