If you feel you may have been exposed to parvovirus (slapped cheek) in your pregnancy then please contact your community midwife or GP to have a blood test to check if you are already immune to the virus. If it is found that you have been exposed to parvovirus for the first time in this pregnancy you will need follow up with a fetal medicine consultant. A leaflet explaining more about Parvovirus.
