cord-304115-xs54f295	Zamaniyan, Marzieh	Preterm delivery in pregnant woman with critical COVID‐19 pneumonia and vertical transmission	2020-04-17		.txt	text/plain	1793	98	51	Given the patient's history and fever and cough, two nasal and throat swab samples were taken and tested to be positive for SARS-CoV-2 with SuperScript III Platinum, Quantitive Real-time PCR system Kits (Invitrogen company, USA) 4 . The RT-PCR tests was positive for amniotic fluid and neonate, suggesting the infant might have been affected intrauterine by COVID-19; therefore, once more, it raised the concerns regarding possible vertical transmission of the virus in mothers with serious illness. In some previous studies, the authors reported 21 healthy babies delivered by infected mothers to COVID-19, but they could not detect the virus in any of the feto-maternal parts namely placenta, amniotic fluid and cord blood [9] [10] [11] . The current case study, once again, raises concerns regarding possible vertical transmission of COVID-19 in pregnant women infected by SARS CoV-2 in contrast to the findings reported in some small studies published previously.	./cache/cord-304115-xs54f295.txt	./txt/cord-304115-xs54f295.txt
