There are currently no data suggesting an increased risk of miscarriage or early pregnancy loss in relation to COVID-19. Case reports from early pregnancy studies with SARS and MERS do not demonstrate a convincing relationship between infection and increased risk of miscarriage or second-trimester loss.
Reports from the USA conquers with similar research reports from China. It says that when a woman becomes infected at any stage of pregnancy, with Covid-19, the born child shows no vertical transmission of COVID-19 infection.
They were 82 patients in this study, with 28 pregnant and 54 of similar age none-pregnant women, 7.1% were mild type and 24 were in moderate type category. Only 2 pregnant patients were categorized as severe pneumonia.
There was no association between the severity of COVID-19 and pregnancy.
22 pregnant women, delivered 23 live births either by cesarian section or vaginal delivery.
The good news was in their study 'NO' neonate was infected by COVID-19 infection.
This is a small study and further research is needed to conclude their findings.
Two reports have published evidence of IgM for SARS-COV-2 in neonatal serum at birth. Since IgM does not cross the placenta, this is likely to represent a neonatal immune response to in utero infection.
China suggested that there was no evidence for this and amniotic fluid, cord blood, neonatal throat swabs, placenta swabs, genital fluid, and breastmilk samples from COVID-19 infected women and their babies have so far all tested negative for the virus.
