Question: How much is known about the transmission of COVID-19 from mother to baby during pregnancy?

Answer passage (source: WHO):
page_title: Q&A: Pregnancy, childbirth and COVID-19
section_headers: Are pregnant women at higher risk from COVID-19?
section_content: Research is currently underway to understand the impacts of COVID 19 infection
on pregnant women. Data are limited, but at present there is no evidence that
they are at higher risk of severe illness than the general population.
However, due to changes in their bodies and immune systems, we know that
pregnant women can be badly affected by some respiratory infections. It is
therefore important that they take precautions to protect themselves against
COVID-19, and report possible symptoms (including fever, cough or difficulty
breathing) to their healthcare provider.
WHO will continue to review and update its information and advice as more
evidence becomes available.

Reviewer feedback on this answer:
Talks about the risk of COVID-19 to pregnant women, but doesn't discuss the risk of transmision to babies.
This response mostly talks about how pregnant women may be at increased risk because of changes to their immune system but it doesn't really mention about what could pass to the baby

Answer passage (source: WHO):
page_title: Q&A: HIV, antiretrovirals and COVID-19
section_headers: Should pregnant and breastfeeding women living with HIV with COVID-19 and their newborns be managed differently?
section_content: There is currently no known difference between the clinical manifestations of
COVID-19 or risk of severe illness or foetal compromise for pregnant and non-
pregnant women or adults of reproductive age. Pregnant and recently pregnant
women with suspected or confirmed COVID-19 should be treated with supportive
and management therapies, considering the immunologic and physiologic
adaptations during and after pregnancy which may overlap with COVID-19
symptoms. Data are limited but, until the evidence base provides clearer
information, special consideration should be given to pregnant women with
concomitant medical illnesses who could be infected with COVID-19. There are
no reported deaths in pregnant women at time of publishing this
information[17] however, COVID-19 testing of symptomatic pregnant women may
need to be prioritized to enable access to specialized care. All recently
pregnant women with COVID-19 or who have recovered from COVID-19 should be
provided with information and counselling on safe infant feeding and
appropriate IPC measures to prevent COVID-19 virus transmission[18].
With confirmed disease or under investigation, management is similar to non-
pregnant women, with appropriate isolation of confirmed or under
investigation. Obstetric facilities must be notified and prepared, noting that
each infant born to any mother with confirmed COVID-19 should be considered a
‘person under investigation’ and should be isolated according to the IPC
guidance. Currently, it is unknown whether newborns with COVID-19 are at
increased risk for severe complications.

Reviewer feedback on this answer:
It feels like this response never gets to the heart of what's being asked. It seems to mostly just compare pregnant and non-pregnant women but doesn't talk about transmission to the baby
Specifies what is and is not known about the risk of COVID-19 transmission during pregnancy.

Answer passage (source: WHO):
page_title: Q&A: Pregnancy, childbirth and COVID-19
section_headers: Can COVID-19 be passed from a woman to her unborn or newborn baby?
section_content: We still do not know if a pregnant woman with COVID-19 can pass the virus to
her foetus or baby during pregnancy or delivery. To date, the active virus has
not been found in samples of amniotic fluid or breastmilk.

Reviewer feedback on this answer:
Clearly answers the question about how much is known about whether pregnant women can transmit the virus to their babies.
They want to know how much is known about mother to baby transmission and this response states that not much is known so that's what was being asked.
