cord-349656-baoqgu8v	Wang, Chen	Intrauterine vertical transmission of SARS‐CoV‐2: what we know so far	2020-04-07		.txt	text/plain	735	62	68	[2] In a study by Chen et al., [3] paired neonatal pharyngeal swab samples and placental tissues of three pregnant women with COVID-19 were used as samples to evaluate the potential risk of intrauterine vertical transmission, and all samples tested negative for SARS-CoV-2 RNA. Notably, a neonate born to a pregnant woman with COVID-19 tested positive for SARS-CoV-2 RNA in the pharyngeal swab sample at 36 hours after birth was subsequently confirmed that the qRT-PCR testing of the placenta and cord blood was negative for SARS-CoV-2, suggesting that intrauterine vertical transmission might not have occurred. Furthermore, in a cohort study by Zeng et al., [13] 3 of 33 (9%) infants were diagnosed with neonatal early-onset infection with SARS-CoV-2 based on positive qRT-PCR results of the nasopharyngeal and anal swabs in two consecutive tests at day 2 and 4 of age. Possible vertical transmission of SARS-CoV-2 from an infected mother to her newborn.	./cache/cord-349656-baoqgu8v.txt	./txt/cord-349656-baoqgu8v.txt
