A Mother Transmitted COVID-19 to Her Baby During Pregnancy

A Mother Transmitted COVID-19 to Her Baby During Pregnancy

Though each mom and child recovered, the case highlights the significance of limiting COVID-19 publicity for pregnant ladies.

A pregnant mom who examined optimistic for COVID-19 transmitted the virus inflicting the illness to her prematurely born child, UT Southwestern physicians report. Each had been handled and recovered.

The case, detailed in an article revealed final month in The Pediatric Infectious Illness Journal, provides to a rising physique of proof that the SARS-CoV-2 virus might be transmitted in utero. It additionally underscores the significance of limiting COVID-19 publicity for pregnant ladies.

“Particularly with the rising prevalence of the virus right here in Texas, it’s essential to deliver to the forefront this discovering that moms and infants might be affected by COVID-19, transmission can happen throughout being pregnant, and pregnant moms want to shield themselves,” says Amanda Evans, M.D., an assistant professor of pediatrics specializing in infectious ailments at UT Southwestern and senior writer of the paper. “We don’t know whether or not there are any long-term results of COVID-19 an infection in infants.”

Though greater than 20 million individuals world wide have been contaminated with SARS-CoV-2 – the virus that causes COVID-19 – information on how the virus impacts pregnant ladies have been restricted. An early examine out of Wuhan, China, concluded that SARS-CoV-2 transmission from mom to child was unlikely, for the reason that researchers discovered no copies of the virus in any amniotic fluid, umbilical wire blood, or breast milk. However a handful of more moderen research have prompt there could also be remoted situations through which such viral transmission does happen throughout being pregnant.

Within the case described within the paper, a girl who was 34 weeks pregnant visited the emergency room with indicators of untimely labor and was admitted to the COVID unit at Parkland Memorial Hospital when she examined optimistic for the SARS-CoV-2 virus. Whereas she didn’t have the standard respiratory signs related to COVID-19, she did have a fever and diarrhea, which prompt doable viral an infection.

“At the moment, we had been doing common testing of anybody with the commonest signs of COVID-19, together with respiratory signs and gastrointestinal signs,” says Wilmer Moreno, M.D., an assistant professor of obstetrics and gynecology at UTSW who was concerned within the case.

The girl, who didn’t understand how she acquired the virus, remained hospitalized due to her COVID-19 analysis. Three days after admission, her water broke. Following an eight-hour labor in early Could, she gave beginning to a wholesome 7-pound, 3-ounce woman.

“The newborn actually did high-quality the primary 24 hours of life,” says Julide Sisman, M.D., an affiliate professor of pediatrics who cared for the new child and first writer of the paper. “However as a result of she was prematurely born to a COVID-19-positive mom, we did admit her to the NICU in a particular space away from different infants.”

About 24 hours after beginning, the new child developed a fever that spiked, and he or she additionally confirmed indicators of respiratory misery, together with an abnormally excessive respiration charge and decrease ranges of oxygen in her blood. Sisman and her colleagues ran assessments for viruses and micro organism. Whereas different assessments got here again destructive, a COVID-19 check was optimistic at each 24 and 48 hours after beginning.

“At the moment, the information we had was that transmission doesn’t happen in utero, so we actually weren’t anticipating that in any respect,” says Sisman.

To assist pin down how and when the transmission between mom and child occurred, Dinesh Rakheja, M.D., a UTSW professor of pathology who holds the John Lawrence and Patsy Louise Goforth Chair in Pathology, analyzed the placenta from the being pregnant.

“We discovered indicators of irritation and proof that the child had been harassed,” says Rakheja. “After which, to search for the virus, we did assessments past these routinely performed.”

He and his colleagues first examined skinny slices of the placenta beneath an electron microscope, recognizing constructions that seemed like viruses. Then they examined small samples of the placenta for the SARS-CoV-2 virus. At present out there industrial assessments for the COVID-19 virus all depend on bodily fluids, somewhat than strong tissues, to check for the virus. So Rakheja co-opted a check that had initially been developed for the 2003 SARS virus. Tailored for the brand new coronavirus, the immunohistochemical check enabled the pathologist to establish the nucleocapsid protein of the SARS-CoV-2 virus.

Neither the mom nor the child had extreme sufficient signs to warrant therapy apart from oxygen and fluids, and each totally recovered. The newborn stayed within the hospital for 3 weeks and was then launched.

“A few week later, I adopted up with the household and the child was doing actually nice, and nonetheless gaining weight,” says Evans. “The mother was additionally doing properly.”

Extra information – together with not solely particular person case experiences however giant cohort research – are wanted to higher perceive how COVID-19 impacts each pregnant ladies and infants, the physicians agree. At UTSW, the case elevated consciousness that it’s doable for newborns to be born already harboring the virus.

“The truth that this could happen, even when uncommon, illustrates how necessary it’s to restrict publicity for moms and newborns,” says Moreno. “Something, like telemedicine visits, that may get rid of the necessity for mother to be round different individuals can be very useful.”
