Measles and Viral Infections: Symptoms and Vaccination Advice

Measles is one of the most contagious infectious diseases known. It spreads easily through the air and can cause serious illness, particularly in young children, pregnant women, and people with weakened immune systems. New Zealand has seen measles outbreaks in recent years, linked to gaps in immunisation coverage. The good news is that measles is highly preventable through vaccination. This guide explains what measles is, how to recognise it, what to do if you think you have been exposed, and how the free MMR vaccine protects you and your community.

If you think you or your child has measles, do not walk into a clinic or emergency department. Measles is extremely contagious and can spread in a waiting room within minutes. Phone your GP or call Healthline on 0800 611 116 first, so the clinic can arrange to see you safely without putting others at risk.

What is measles?

Measles is a viral infection caused by the measles virus. It is spread through the air when an infected person coughs, sneezes, or breathes, and the virus can linger in a room for up to two hours after that person has left. Because so many people are susceptible if they are not immune, around nine in ten non immune people exposed to the virus will catch it. Measles is a notifiable disease in New Zealand, which means health services track and respond to cases to limit spread.

Symptoms of measles

Measles usually develops in two stages. Symptoms typically appear 7 to 14 days after exposure, and the illness often feels worse than a common cold.

Early symptoms (first 3 to 5 days)

  • A high fever, often above 39 degrees Celsius
  • A dry cough
  • A runny or blocked nose
  • Red, watery, and sore eyes, sometimes with sensitivity to light
  • Tiny white spots inside the mouth (Koplik spots), which can appear before the rash
  • Feeling generally unwell, tired, and off food

The measles rash

  • A red, blotchy rash that usually starts 3 to 5 days after the first symptoms
  • Begins on the face and hairline, then spreads down the neck, body, arms, and legs
  • The spots may join together into larger blotchy areas
  • The fever often stays high while the rash spreads
  • The rash typically fades after about a week

How measles spreads

Measles spreads through airborne droplets and direct contact with nose or throat secretions. It is far more contagious than influenza or most other viruses. A person with measles is infectious from around five days before the rash appears until four days after it appears, which means the virus often spreads before anyone realises it is measles. One infected person can pass measles to 12 to 18 non immune people.

Possible complications

Most people recover from measles, but complications are common and can be serious, especially in young children and adults.

  • Common: ear infections, diarrhoea, and dehydration.
  • Chest infection: pneumonia is the most common cause of measles related death.
  • Brain inflammation: encephalitis affects around 1 in 1,000 cases and can cause lasting harm.
  • In pregnancy: measles raises the risk of miscarriage, premature birth, and low birth weight.
  • Rare and late: subacute sclerosing panencephalitis (SSPE), a fatal brain condition that can develop years after infection.

Seek urgent medical advice (phone first) if someone with measles has:

  • Difficulty breathing or rapid breathing
  • Drowsiness, confusion, or a seizure
  • A stiff neck or severe headache
  • Signs of dehydration, such as little or no urine
  • A high fever that will not come down, or symptoms that are getting worse

Are you protected? Checking your immunity

You are considered immune to measles if you have had two documented doses of the MMR vaccine, or a blood test confirms immunity, or you were born before 1969 (people from this era almost always caught measles in childhood and developed natural immunity). If you are unsure of your vaccination history, it is safe to have another MMR dose.

The MMR vaccine in New Zealand

MMR protects against measles, mumps, and rubella. Two doses give strong, long lasting protection against measles for almost everyone who receives them. In New Zealand the MMR vaccine is funded and free for anyone who is not already immune, regardless of visa or citizenship status.

  • Children are offered MMR at 12 months and again at 15 months under the National Immunisation Schedule
  • Free catch up doses are available for older children, teenagers, and adults who have missed either dose
  • Adults who are unsure whether they had two doses can safely have a catch up MMR
  • MMR is not given during pregnancy, so plan vaccination before pregnancy where possible
  • People with severely weakened immune systems should discuss timing with their GP

What to do if you suspect measles

  • Stay home and keep away from others, especially babies, pregnant women, and anyone with a weakened immune system
  • Phone your GP or Healthline on 0800 611 116 before going anywhere, so you can be assessed without exposing others
  • Follow the advice given about isolation, which is usually until four days after the rash appears
  • Rest, drink plenty of fluids, and use paracetamol for fever and discomfort
  • Let the clinic know about anyone you have been in close contact with, so they can be checked

Frequently asked questions

How long is measles contagious?

A person with measles is infectious from about five days before the rash appears until four days after it appears. This is why measles spreads so easily, since people are contagious before they know they have it. Staying home during this period is important to protect others.

Is the MMR vaccine safe?

MMR has been used worldwide for decades and has a strong safety record. Most side effects are mild, such as a sore arm, low grade fever, or a brief rash. Serious reactions are very rare. The benefits of protection against measles, mumps, and rubella greatly outweigh the small risk of side effects.

Can adults get measles?

Yes. Adults who are not immune can catch measles, and they often become more unwell than children. Many adults in New Zealand missed one or both MMR doses growing up. If you are unsure of your history, a free catch up dose is available through your GP.

I had measles as a child. Do I still need the vaccine?

If you had a confirmed case of measles, you are very likely to be immune for life and do not need MMR for measles protection. If you are not certain, having an MMR dose is safe and ensures you are also protected against mumps and rubella.

Why are measles cases rising again?

Measles outbreaks happen when immunisation rates drop below the level needed to stop the virus spreading. When fewer people are vaccinated, the virus can move quickly through a community. Keeping MMR coverage high is the most effective way to prevent outbreaks.
