Rubella transmission in pregnancy

A person with rubella can release the virus in droplets from the nose and mouth. Someone nearby may breathe them in, or pick up the virus after touching contaminated secretions and then touching the face. A person can spread rubella before recognising the illness, so exposure may occur without an obvious rash. Rubella itself may cause a mild rash, fever, swollen glands or joint pain; these symptoms are also described on the Rubella, Fever, Swollen Glands and Joint Pain pages. Infection in pregnancy can pass through the placenta to the developing baby, particularly early in pregnancy, which is why suspected exposure should not be managed by waiting for symptoms alone.

Contact your maternity team or a GP consultation service promptly and explain when the contact happened, whether the other person had confirmed rubella, and how many weeks pregnant you are. Avoid close contact with people who may be pregnant until you receive advice, and call before attending a clinic if you have a rash or fever so the service can reduce exposure to others. Do not arrange an MMR vaccination during pregnancy without specific clinical advice; immunity and next steps can be checked after assessment.

Seek same-day advice after known rubella exposure during pregnancy, even if you feel well. Contact a clinician promptly for a new rash, fever, swollen glands or joint pain after possible exposure. Ask for urgent help if you become very unwell, have trouble breathing, cannot keep fluids down, or have pregnancy symptoms that concern you. A clinician may review your vaccination history and arrange testing or follow-up based on the timing of exposure.

Ask whether you are immune, whether testing is appropriate now or later, what symptoms should trigger another call, and how to protect household members. You can also ask about the MMR Vaccination page and whether a GP Consultation is the right route for follow-up.
