Based on the analysis of 176 reported infant cases, the researchers found that most (70%) newborn novel coronavirus infection (SARS-COV-2) was caused by environmental exposure, while the other 30% reported cases may be caused by environmental exposure. Vertical contraction from the mother.

Daniele De Luca, correspondent and colleague of Saint-Université de Paris, conducted a meta-analysis of the published neonatal novel coronavirus infection (within 30 days after birth), in which viral infection was defined as at least one nasopharyngeal swab test and/or the detection of positive specific antibodies in blood. They analyzed 176 cases as of August 30, 2020, and found that 70% of the cases were caused by environmental exposure, 30% may be the result of vertical transmission (mother-to-child transmission of the virus), and about 9% of 176 cases were diagnosed as vertical transmission, which may occur before or during delivery.

According to the author's analysis, 55% of infants (97 cases) later developed coronavirus pneumonia-19, and their clinical symptoms seemed similar to those reported by elderly patients, including respiratory symptoms (52% cases), fever (44%), gastrointestinal symptoms (36%) and nervous system symptoms (18%). In addition, when studying the infection that occurred at least 72 hours after birth, the author of this paper found that the infection rate of infants who shared a room with their mothers in the sample-hospital cribs placed beside their mothers' beds-seemed to be higher. Novel coronavirus infection. They believe that if the mother and son live together, they should provide appropriate sanitary measures and protective equipment to reduce the risk of transmission caused by environmental exposure.

The author also points out that breastfeeding has nothing to do with novel coronavirus infection, which shows that the virus is rarely transmitted through breast milk, and further research is needed in this aspect.
