What is measles?
Measles can be a serious disease. It's caused by a virus. Measles spreads very easily from one person to another. Measles is also known by the names morbilli or rubeola.
Measles is the most common vaccine-preventable cause of death among children throughout the world.
What are the signs and symptoms of measles?
It usually takes 10 - 12 days from contact with someone with measles to the first symptom appearing but it can take from 7-18 days. This is called the incubation period.
The illness begins with the following, which last for 2 to 4 days:
- high fever
- runny nose
- loss of appetite
- sore red eyes (conjunctivitis or 'pink eye')
You can sometimes see small white spots (Koplik spots) inside the mouth near the back teeth early in the disease, as in the photo.
A rash follows and the white spots inside the mouth fade. The rash appears on the head and gradually spreads down the body to the arms and legs, as in the photos. It lasts for up to one week.
A person who has measles is most infectious in the early stages of their disease - from 5 days before the symptoms first appear to 5 days after the appearance of the rash.
Children usually look and feel quite unwell and miserable with measles. They are most unwell during the first day or two after the appearance of the rash.
How serious is measles?
1 in 10 people with measles will get complications.
1 - 3 out of 1,000 people with measles will die in developed countries.
1 in 10 people with measles will get complications including:
- ear infections
- other diseases of the airways (like bronchiolitis and croup)
- ulcers of the eye (corneal ulcers)
- idiopathic thrombocytopenic purpura (low platelets)
Measles in pregnancy increases risk for premature labour, miscarriage and stillbirth.
1 in 1000 people with measles develop inflammation of the brain (encephalitis ) - 15 in 100 of these people die and approximately 30 in 100 are left with permanent brain damage.
1 in 100,000 people who have had measles will, years later, develop a serious brain inflammation called subacute sclerosing panencephalitis (SSPE). This serious complication always results in death.
Who is most at risk of complications from measles?
- children under 5
- adults over 20
- those with long-lasting (chronic) diseases
- those with a weakened infection-fighting (immune) system
- those who are malnourished
How do you catch measles?
Measles is very easy to catch. It spreads through the air by infectious droplets through coughing, sneezing and talking, or by touching a surface with infected saliva or mucus.
Who is most at risk of catching measles?
- all children who have not received at least 1 dose of MMR
- anyone with certain immune deficiencies is at special risk - these children often can't be immunised and rely on protection from those around them
- pregnant women - measles during pregnancy increases the risk of premature labour, miscarriage, and low birth weight infants
Can I do anything to prevent my child catching measles?
Immunisation given on time is the only way to prevent measles. 2 doses of the measles, mumps, rubella (MMR) vaccine is 99 percent effective in preventing measles.
See the page about measles immunisation on this website.
What should I do if I think my child has measles?
Phone Healthline on 0800 611 116 or your family doctor as soon as possible for advice. Make sure to phone your doctor before visiting. That way they can take steps to make sure you don't wait in a public area where other people might catch measles from your child.
How do I prevent measles spreading?
If your child has measles, you will need to keep them away from other people (in isolation). That means staying away from:
- daycare, early childhood services or school
- group and social activities
- sports and recreation events
- public places like cinemas and shopping malls
- work and community gatherings
You should only see people who are immune to measles when you are in isolation.
Your child will need to stay in isolation until they are no longer infectious. The infectious period usually ends 5 days after the appearance of the rash. Your public health service or family doctor should give you advice about this. They should also give advice to people who have been in contact with your child and are at risk of catching measles.
What is the treatment for measles?
Because measles is caused by a virus, there is no specific treatment.
Antibiotics are not helpful for measles and your doctor won't give them to your child unless your child also develops a bacterial infection as a complication of measles.
In severe cases of measles, particularly when there are more serious complications, hospital treatment may be necessary.
How can I care for my child with measles at home?
- give paracetamol for pain or discomfort if needed - you must follow the dosage instructions on the bottle - it is dangerous to give more than the recommended dose
- never give your child or young person aspirin as this may increase the risk of Reye syndrome, which is a rare and serious illness
- see information about treating fever
- give your child fluids often, to prevent dehydration
- use saltwater drops (saline) to treat a stuffy nose - ask your pharmacist or family doctor for instructions
- use damp cotton wool to clean away any crustiness around the eyes - use one piece of cotton wool per wipe for each eye and gently clean the eye from inner to outer lid
- keep your child at home and resting until they are well and your public health service advises that they can return to school or daycare
When should I seek help for my child with measles?
When do I need to see a doctor urgently?
You need to see a doctor urgently if your child:
- is under 3 months old

- is very irritable and is not wanting to be held
- is becoming less responsive
