cord-282449-7mxp3sdy	A, Amouroux	Evidence for and against vertical transmission for SARS-CoV-2 (COVID-19)	2020-05-04		.txt	text/plain	1511	95	55	Abstract COVID-19 can severely affect pregnant women and the issue of vertical transmission of sars-cov-2 has also emerged. Sars-cov-2 could be recovered by real-time (RT) PCR from nasal and throat swabs, sputum and feces of symptomatic patients including neonates but not from vaginal swabs, amniotic fluid, placenta, cord blood, neonatal blood or breast milk. Detection rates of real-time PCR and the interpretation of IgM and IgG antibodies levels in cord and neonatal blood are discussed in relation with the immaturity of the fetal and neonatal immune system. Based upon RT-PCR identification of SARS-CoV-2 virus, early reports from China suggested that intrauterine vertical transmission was unlikely 1 . Total (Ab) and IgG antibodies seem to be acquired over 2 weeks' in infected individuals from the onset of symptoms and the introduction of SARS-CoV-2 serology is a rapidly evolving field of research and much-needed aid in the management of the pandemic.	./cache/cord-282449-7mxp3sdy.txt	./txt/cord-282449-7mxp3sdy.txt
