Download the Guidance on viral rash in pregnancy PDF.
This document updates and consolidates previous guidance, specifically the 2000 report of the Public Health Laboratory Service (PHLS - now Public Health England, Working Group, as of 1 April 2013).
A specialist Working Group was established to review all currently available scientific evidence and consult with experts where required. The revised guidelines were published in January 2011 and aim to help decision making in the investigation and management of pregnant women who have 'a rash compatible with a systemic viral illness', or who have had contact with a person with such an illness. It addresses particularly measles, rubella, parvovirus B19, and chickenpox infection, but considers other infective causes of viral rash illness in the UK. It gives the magnitude and degrees of risk to the fetus in terms of outcomes for the gestation at which maternal infection occurs.
