Are pregnant women more susceptible to infection, or at increased risk for severe illness, morbidity, or mortality with COVID-19, compared with the general public?

There is no information from published scientific reports about susceptibility of pregnant women to COVID-19. Pregnant women experience immunologic and physiologic changes which might make them more susceptible to viral respiratory infections, including COVID-19. 

Are pregnant women with COVID-19 at increased risk for adverse pregnancy outcomes?

There is no information on adverse pregnancy outcomes in pregnant women with COVID-19. Pregnancy loss, including miscarriage and stillbirth, has been observed in cases of infection with other related coronaviruses [SARS-CoV and MERS-CoV] during pregnancy. High fevers during the first trimester of pregnancy can increase the risk of certain birth defects.

Can pregnant women with COVID-19 pass the virus to their fetus or newborn (i.e. vertical transmission)?

The virus that causes COVID-19 is thought to spread mainly by close contact with an infected person through respiratory droplets. Whether a pregnant woman with COVID-19 can transmit the virus that causes COVID-19 to her fetus or neonate by other routes of vertical transmission (before, during, or after delivery) is still unknown. However, in limited recent case series of infants born to mothers with COVID-19 published in the peer-reviewed literature, none of the infants have tested positive for the virus that causes COVID-19. Additionally, virus was not detected in samples of amniotic fluid or breastmilk.

Are infants born to mothers with COVID-19 during pregnancy at increased risk for adverse outcomes?

Based on limited case reports, adverse infant outcomes (e.g., preterm birth) have been reported among infants born to mothers positive for COVID-19 during pregnancy. However, it is not clear that these outcomes were related to maternal infection, and at this time the risk of adverse infant outcomes is not known. 

Is maternal illness with COVID-19 during lactation associated with potential risk to a breastfeeding infant?

Human-to-human transmission by close contact with a person with confirmed COVID-19 has been reported and is thought to occur mainly via respiratory droplets produced when a person with infection coughs or sneezes.

In limited case series reported to date, no evidence of virus has been found in the breast milk of women with COVID-19. No information is available on the transmission of the virus that causes COVID-19 through breast milk (i.e., whether infectious virus is present in the breast milk of an infected woman).
