Pregnant women with Covid in their last trimester are three times as likely to give birth early - a risk that rises to seven-fold for those after their 34th week of pregnancy, a new study reports.
The Israeli study of more than 5,000 mums-to-be is one of the first to look at pregnancy outcomes for Covid patients by trimester. Researchers advised mums-to-be to wear masks and social distance to reduce their risk of infection.
For Covid infections in the first and second trimesters, the study found no association with increased risk of preterm birth. It also reported no difference in the chances of losing a baby between infected and non-infected women.
