Varicella during pregnancy: what to know

A new itchy blistering rash, fever or known contact with chickenpox should be reported to the maternity or medical team. The significance can depend on the stage of pregnancy, previous immunity, symptoms and timing of exposure. The clinician may coordinate follow-up for both the pregnant person and baby; this does not mean a complication is certain.

Call for advice before going to a clinic, because an unplanned visit could expose other patients. Mention the date of contact, whether you have had chickenpox or vaccination, and any rash or fever. Do not start antiviral or other medicines without guidance; Antiviral Treatment may be considered after an individual assessment. Avoid contact with vulnerable people until advised.

Seek urgent medical help for breathing difficulty, chest pain, confusion, severe headache, inability to keep fluids down, or rapidly worsening symptoms. Contact your maternity team promptly after a significant exposure or at the first sign of fever or Skin Blisters, even if the rash seems limited.

Ask whether you need testing, treatment, monitoring or an appointment; how to protect household contacts; and whether Chickenpox Vaccination can be considered after pregnancy if you are not immune.
