Overview
Measles is an infection that spreads very easily. It is usually mild, but it can lead to serious complications in some people, which is why preventing it matters [1].
Symptoms
Measles often starts with cold-like symptoms such as a high temperature, a runny nose and sore, watery eyes, followed a few days later by a rash that usually starts on the face and spreads. Small white spots may also appear inside the mouth [1].
The MMR vaccine
The MMR vaccine protects against measles (as well as mumps and rubella) and is the best way to prevent it. It is offered to children as part of the NHS vaccination schedule [1].
What to do
Ask for an urgent GP appointment or call NHS 111 if you think you or your child has measles — phone first rather than going in, so it does not spread. Stay off school or work for at least 4 days after the rash appears, and avoid close contact with babies, pregnant women and people with weakened immune systems [1].
