Measles is an infection that spreads very easily. It's unpleasant and can sometimes have serious complications. Having the measles,mumps and rubella (MMR) vaccine is the best way to prevent it.
Anyone can get measles if they haven't been vaccinated or they haven't had it before. It's most common in young children.
Measles usually clears in around 7 to 10 days.
Symptoms of measles
The first symptoms of measles develop around 10 days after you're infected. These can include:
- cold-like symptoms, such as a runny nose, sneezing, and a cough
- sore, red eyes that may be sensitive to light
- watery eyes
- swollen eyes
- a high temperature (fever), which may reach around 40°C (104°F)
- small greyish-white spots in the mouth
- aches and pains
- loss of appetite
- tiredness, irritability and a general lack of energy
The measles rash appears around 2 to 4 days after the initial symptoms and normally fades after about a week. The rash:
- is made up of small red-brown, flat or slightly raised spots that may join together into larger blotchy patches
- usually first appears on the head or neck, before spreading outwards to the rest of the body
- is slightly itchy for some people
If you or your child have measles and:
- shortness of breath
- a high temperature that does not come down after taking paracetamol or ibuprofen
- is coughing up blood
- fits (convulsions)
You need urgent help.
Go to the nearest Hospital Emergency (A&E) Department or phone 999

Self care - treatment for measles
There are things you can do to help relieve your symptoms:

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
How measles can be prevented
Measles can be prevented by having the MMR vaccine.
This is given in 2 doses as part of the NHS childhood vaccination programme.
You can be vaccinated at any age if you haven't been fully vaccinated before.
If the MMR vaccine isn't suitable for you, a treatment called human normal immunoglobulin (HNIG) can be used if you're at immediate risk of catching measles.
