No vertical transmission of the new coronavirus has been detected

pregnant mother and baby safe if they are diagnosed with new crown pneumonia? On February 13th The Lancet published a retrospective study of nine pregnant women with neo-coronary pneumonia, saying there was no definitive evidence that infection with the new coronavirus could cause serious adverse consequences in newborns, nor had fetal infections caused by vertical transmission in the womb been detected.
the study was carried out by Wuhan University Central South Hospital, Wuhan University School of Basic Medicine, Peking University First Hospital and other institutions. Qiao Jie, a member of the Chinese Academy of Engineering and president of Peking University's Third Hospital, wrote in a commentary published at the same time: In the current emergency situation, the results of the study are of great value to prevention and clinical practice in China and else regions. However, due to the small sample size and short study period, more follow-up studies of pregnant women and infants are needed.
9 patients in the paper ranged in age from 26 to 40 years old, and were admitted to the hospital at 36 to 39 weeks, without diabetes, chronic hypertension and other diseases. After being diagnosed with the new coronavirus, the patient developed fever, cough, muscle pain, sore throat and other symptoms. All patients were treated with nasal intives for oxygen and empirical antibiotics, and 6 were treated with antivirals.
as of 4 February, none of the nine patients had serious cases or deaths. However, due to the small sample size, it is not possible to determine whether there is a risk of mother-to-child transmission during vaginal delivery, and all nine were delivered by caesarean section in the late stages of pregnancy. The researchers tested negative for amniotic water, umbilical cord blood, breast milk samples and newborn pharynx swabs from six patients taken at the site of the caesarean section.
addition, no clinical symptoms are currently present in all newborns and no special paediatric treatment is required.
, due to the affected immune mechanisms, pregnant women are highly susceptible to respiratory diseases and more likely to develop severe diseases, physiological changes can also put pregnant women at higher risk.
For the protection of mothers and babies, the National Health And Wellness Commission on February 12th published a list of designated hospitals for suspected or confirmed pregnant women with new coronavirus infections in various provinces (districts and municipalities). In his comments, Jorge also noted that pregnant women and newborns should be considered critically at high risk and that pregnant women and newborns with suspected and confirmed infections should be isolated in designated locations;
also compared the clinical manifestations of two pregnant women who were diagnosed with SARS and the new coronavirus, which were more prone to adverse maternal and child complications, such as spontaneous abortion, premature birth, limited in-house growth, etc. Pregnant women with newly diagnosed coronary pneumonia are currently observed to have fewer complications and adverse pregnancy outcomes. This is consistent with the findings of a previous study published by the Hubei Provincial Maternal and Child Health Hospital: no evidence of vertical mother-to-child transmission of the new coronavirus has been found.
