Measles

Measles usually starts with cold-like symptoms, followed by a rash a few days later. Some people may also get small spots in their mouth.

Cold-like symptoms

The first symptoms of measles include:

  • a high temperature
  • a runny or blocked nose
  • sneezing
  • a cough
  • red, sore, watery eyes

Spots in the mouth

Small white spots may appear inside the cheeks and on the back of the lips a few days later. These spots usually last a few days.

The measles rash

A rash usually appears a few days after the cold-like symptoms.

The rash starts on the face and behind the ears before spreading to the rest of the body.

The spots of the measles rash are sometimes raised and join together to form blotchy patches. They're not usually itchy.

The rash looks brown or red on white skin. It may be harder to see on brown and black skin.

If you're not sure it's measles

It's very unlikely to be measles if you've had both doses of the MMR vaccine or you've had measles before.

  • you've been in close contact with someone who has measles and you're pregnant or have a weakened immune system
  • you or your child have a high temperature that has not come down after taking paracetamol or ibuprofen
  • you or your child have difficulty breathing – you may feel more short of breath than usual
  • your baby or young child is not feeding well, or taking less feeds or fluids than usual

Measles usually starts to get better in about a week.

After seeing a GP, there are things you can do to help ease the symptoms and reduce the risk of spreading the infection.

It can help to:

  • rest and drink plenty fluids, such as water, to avoid dehydration
  • take paracetamol or ibuprofen for a high temperature
  • give your child paracetamol or ibuprofen if they're distressed or uncomfortable – check the packaging or leaflet to make sure the medicine is suitable for your child, or speak to a pharmacist or GP if you're not sure
  • use cotton wool soaked in warm water to gently remove any crusts from your or your child's eyes

Important

Stay off nursery, school or work for at least 4 days from when the rash first appears.

Also try to avoid close contact with babies and anyone who is pregnant or has a weakened immune system.

Measles is spread when an infected person breathes, coughs or sneezes.

You’re infectious from when you first have symptoms (around 4 days before the rash appears) until 4 days after you get the rash.

There are things you can do to reduce the risk of spreading or catching measles.

  • are unable to stay awake – cannot keep their eyes open for more than a few seconds
  • suddenly become confused – your child may be very unsettled, behaving differently, or crying non-stop
  • your child is limp, floppy or not responding normally – their head may fall to the side, backwards or forwards, or they may find it difficult to lift their head and focus on your face

The MMR vaccine can prevent measles. It also protects you from mumps and rubella.

The MMR vaccine is offered to all children in the UK. 2 doses can give lifelong protection against measles, mumps, and rubella.

Ask at your GP surgery if you're not sure you or your child have had the vaccine. They can give it for free on the NHS.
