NEW YORK: Covid-19 can be transmitted in the womb, say researchers after a case study provides evidence of intrauterine (in the womb) transmission of the novel coronavirus from mother to infant.
A US baby girl born prematurely to a mother with Covid-19 is the strongest evidence to date that intrauterine transmission of (SARS-CoV-2) can occur, the findings published in the Pediatric Infectious Disease Journal reported.
"Our study is the first to document intrauterine transmission of the infection during pregnancy, based on immunohistochemical and ultrastructural evidence of SARS-CoV-2 infection in the fetal cells of the placenta," said study lead author Amanda S Evans from the University of Texas Southwestern Medical Centre in the US.
The authors report on an infant delivered to a mother diagnosed with Covid-19, who also had type 2 diabetes. The infant was born at 34 weeks' gestation after the mother had premature rupture of the membranes.
The baby was born "large for gestational age" (LGA) - an important complication in infants of diabetic mothers. She was treated in the neonatal ICU due to prematurity and possible coronavirus exposure.
The infant appeared initially healthy, with normal breathing and other vital signs. On the second day of life, she developed a fever and relatively mild breathing problems.
"It is unlikely that the respiratory distress observed in this infant was due to prematurity since it did not start until the second day of life," the researchers wrote. (IANS)
