Measles and pregnancy

Measles (Opens in new tab) is a contagious illness caused by a virus. It can make you very unwell and lead to serious complications.

Measles is now quite rare in Australia due to a successful vaccination program. Sometimes measles outbreaks still occur when travellers become infected while overseas and bring measles back to Australia. For this reason, it's important to make sure that everyone in your family is protected by getting vaccinated.

Measles is caused by a virus. Anyone who has not already had measles or been vaccinated can catch it.

Measles is very contagious. Most unvaccinated people who have contact with someone with measles will get sick.

Measles is spread through:

• coughing and sneezing
• touching objects that have infected mucus or body fluids on them

The virus can survive in the air and on surfaces for a couple of hours.

When you have measles, you're contagious from the day before you start to feel unwell. You remain contagious until 4 days after the rash appears.

If you think you may have measles, you should call your doctor or midwife straight away. You should also speak with your doctor or midwife if you have been in contact with someone with measles.

Do not go to the clinic, because you could infect people in the waiting room. Rather, call your doctor and they will let you know the safest way to see them.

Measles is a notifiable disease (Opens in new tab). If you have measles, your doctor will tell your local public health unit. They may ask to talk with you to try and find out where you caught measles. They may also ask who you have been in contact with (this is called contact tracing (Opens in new tab)). This helps limit the spread of measles and protects your community.

Measles can be a very serious illness, with some people needing to go to hospital.

Common complications include middle ear infection (Opens in new tab) and pneumonia (Opens in new tab) (lung infection). A rare but life-threatening complication of measles is inflammation of the brain (Opens in new tab).

If you're pregnant, you have a higher chance of complications such as pneumonia. You are more likely to need to go to hospital.

How can measles affect my pregnancy?

A measles infection during pregnancy can lead to miscarriage or premature birth. It can also affect your baby's growth.

If you are pregnant, you should not be vaccinated for measles until after you've had your baby.

How can measles affect my unborn baby?

Having measles in pregnancy will not cause your baby to have birth differences.

Your baby is more likely to be small (have low birth weight) and born early.

Your baby could catch measles and be born with a rash.

There is no specific treatment for measles.

It's a good idea to:

• rest
• drink plenty of fluids (Opens in new tab)
• take paracetamol (Opens in new tab) for fever — be sure to check the instructions on the packet

Remember, you may need to avoid other pain-relief medicines (Opens in new tab) during pregnancy. Talk to your doctor or pharmacist before taking any medicine during pregnancy.

The best way to protect yourself against measles is through vaccination.

The measles vaccine is given as part of a combined vaccination that protects against several viruses. There are 2 options:

• measles-mumps-rubella vaccine (known as MMR)
• measles-mumps-rubella-varicella vaccine (known as MMRV)

The vaccines contain a live, weakened form of these viruses. You can't have these vaccines during pregnancy, as there are concerns that they may affect the health of your baby. Ask your doctor about getting vaccinated after your baby is born.

It is safe for people who are pregnant to have contact with people who have recently been vaccinated.

I'm planning a pregnancy — should I be vaccinated?

If you want to become pregnant, you should see your doctor for a pre-conception health check.

If you have never had measles and aren't vaccinated, now is a good time to get vaccinated.

Your partner might also want to consider getting vaccinated. The vaccine is recommended for all adults born since 1966 who have never had measles or been vaccinated.

You can check if you've been vaccinated by looking at your Immunisation History Statement (Opens in new tab).

If you've never been vaccinated, you'll need 2 doses of the measles vaccine, at least 4 weeks apart. You should avoid pregnancy for 28 days after vaccination, so keep using contraception until at least a month after your second dose.

If you've had one dose of the measles vaccine, you should have a second dose — even if the first dose was a long time ago.
