Rubella

Rubella is serious if a pregnant woman catches the disease, especially during the first 3 months of her pregnancy. A mother can pass rubella on to her unborn baby.

Summary

Rubella is usually a mild viral illness – but if a pregnant woman catches it, it can lead to birth defects in her unborn baby.

Rubella is spread through the air by breathing, coughing and sneezing.

If you’ve caught rubella, it takes 14–23 days before you get sick. You’ll be infectious from 7 days before the rash appears until at least 4 days after.

A few cases of rubella occur in New Zealand each year.

Stop rubella spreading

If you have rubella you should stay away from school, early childhood centre and work for 7 days from the appearance of the rash. This will help prevent the spread of rubella in your community.

Prevention

Immunisation

Getting immunised before pregnancy is the best way to protect unborn children from rubella.

All children in New Zealand can be immunised against rubella as part of their free childhood immunisations at 15 months and 4 years old.

All women of child-bearing age can be screened to see whether they’re immune to rubella at no cost. If you’re not immune, you’re eligible for free rubella vaccine.

Vaccine

This disease is covered on the New Zealand Immunisation Schedule. The vaccine used is M-M-R® II.

Risks associated with rubella

  • For women in early pregnancy, 85% of babies infected during the first 8 weeks after conception will have a major congenital abnormality such as deafness, blindness, brain damage, or a heart defect. This declines to about 10–20% by 16 weeks of the pregnancy.
  • About 1 in 3000 patients gets thrombocytopaenia (low platelets causing bruising or bleeding).
  • 1 in 6000 develops encephalitis (inflammation of the brain). This usually occurs in young adults. This may result in death.

Risks associated with the vaccine

  • Joint symptoms may occur in 0–3% of children vaccinated. This is mild and short-lasting.

Immunisation is your choice. If you have questions, talk to your doctor or practice nurse or call the Immunisation Advisory Centre free helpline 0800 IMMUNE (0800 466 863).
