What should you do if you’re exposed to chickenpox while pregnant?

If you’ve never had chickenpox, an exposure needs a phone call the same day.

Medically reviewed by Dr. Christopher Sterling, obstetrician ·

The short answer

If you have not had chickenpox (or aren’t sure) and you’re in contact with someone who has chickenpox or shingles, contact your doctor or midwife straight away. Treatment given soon after exposure can help. The same applies to slapped cheek syndrome and measles.

Why it matters

Chickenpox can be more severe in pregnancy and, rarely, affect the baby. Preventive treatment works best when given quickly after contact.

Slapped cheek (parvovirus B19) and measles can also cause complications in pregnancy.

A simple blood test can show whether you’re already immune.

What to do

  • Find out if you’ve had chickenpox — ask family or check your records.
  • After contact with chickenpox, shingles, slapped cheek or measles: call your doctor or midwife that day.
  • Avoid the waiting room until you’ve spoken to them, to protect other pregnant people.

Common questions

Can shingles cause chickenpox in pregnancy?

Yes. Contact with shingles can give chickenpox to someone who isn’t immune, so report it too.
