Based on the data currently available, there is no evidence to suggest that coronavirus poses an increased risk of miscarriage or birth defects. However, some risk factors have recently emerged that increase the likelihood of a more severe course of COVID-19 in pregnant women. This mainly applies to pregnant women who are in a risk group. Transmission of the virus from mother to child does sometimes occur, but scientific knowledge about how often this happens and at what point during the pregnancy is limited.
The effects of COVID-19 in a healthy pregnant woman do not appear to be any different (for the child and the mother) than for other respiratory infections that are caused by viruses and can lead to fever and pneumonia.
Pregnant women do have a slightly increased chance of being admitted to hospital or ICU. However, these figures are low. Extra caution in the treatment provided to pregnant women who are ill may also play a role here. This may lead doctors to admit pregnant women to the ICU sooner as a precaution.
