SARS-COV-2 causes the  infectious disease COVID-19.

Some people with COVID-19 have no symptoms of disease, others may experience a flu-like illness with fever, aching muscles and cough. A small proportion of infected people develop severe disease which can cause significant breathing problems and can require hospital care and intensive care support.


Cases were first reported in December 2019, from Wuhan province in China, and since then have spread across the globe. By July 2021 there have been our 3 million cases in the UK and over 185 million cases worldwide.


SARS CoV-2 is a completely new virus and many of its effects are still unknown, including any potential effects on pregnant women and their unborn children.




In the last year researchers have data from over 11,000 women affected by COVID-19 in pregnancy from across the world.  

We can be reassured that most pregnant women do not appear to be at any greater risk of contracting the infection that the general public, and that the majority of women who do become infected will experience mild to moderate symptoms.

However, there are still many unanswered questions about mother to child transmission of the virus and whether vaccination of the mother gives protection to their babies.


This Study hopes to answer these questions, to provide evidence that will inform guidance and policy decisions for the clinical and public health management of pregnant women, their infants and the staff that care for them.

Doctor Examining a Pregnant Woman

The periCOVID study was set up by a group of doctors and researchers who are interested in understanding if pregnant women who test positive for the novel coronavirus (SARS-COV-2) can transmit the infection to their unborn babies and if baby's of mothers who have been vaccinated against SARS-CoV-2 will be protected from COVID-19 infection.
