Phone your GP urgently if:
you think you or your child might have measles
you’ve been in close contact with someone who has measles and you’ve not been fully vaccinated (had 2 doses of the MMR vaccine) or haven’t had the infection before – even if you don’t have any symptoms
you’ve been in close contact with someone who has measles and you’re pregnant – measles can be serious in pregnancy
you have a weakened immune system and think you have measles or have been in close contact with someone with measles
If your GP is closed, phone 111.
You should phone your GP first before visiting. They can make arrangements to reduce the risk of spreading the infection to others.
Is measles serious?
Measles can be unpleasant, but will usually pass in about 7 to 10 days without causing any further problems.
Once you’ve had measles, your body builds up resistance (immunity) to the virus. It’s highly unlikely you’ll get it again.
However, measles can lead to serious and potentially life-threatening complications in some people. These include infections of the lungs (pneumonia) and brain (encephalitis).
How measles is spread
The measles virus is contained in tiny droplets that come out of the nose and mouth when an infected person coughs or sneezes.
You can easily catch measles by breathing in these droplets. Or, if the droplets have settled on a surface, by touching the surface and then placing your hands near your nose or mouth. The virus can survive on surfaces for a few hours.
People with measles are infectious from when the symptoms develop until about 4 days after the rash first appears.
How to prevent spreading measles to others
If you have measles:
stay off school or work for at least 4 days from when the rash first appears
regularly wash your hands with soap
use and dispose of tissues when you sneeze
avoid close contact with anyone who isn’t fully vaccinated
