The problem of coronavirus infection has captured the whole world. In one year, the views on the disease itself and its treatment have radically changed. Doctors all over the world cannot give definite answers to a number of questions regarding this virus and its impact on newborn babies. Low susceptibility to coronavirus in young children may be due to some peculiarities of the immune system. Today it is considered to be the main ways of transmission of the virus are airborne and contact. However, the airborne route of infection in newborns is unlikely, because from birth the child is isolated from the sick mother. The issue of the vertical transmission of the virus from an infected mother to a child is discussed. There is no evidence of transmission of coronavirus through breast milk. The diagnosis of coronavirus infection in children is established with a positive epidemiological history and with 2 clinical symptoms with laboratory confirmation. The article presents a single clinical case of coronavirus infection in a newborn. The possible ways of infection of the newborn, the clinical picture, the possibility of joint stay of the mother and the child, breastfeeding, and treatment of the newborn are discussed.

The problem of coronavirus infection has been the world’s concern since 2019. At the same time, the issues of infection of newborn children remain unclear, the issue of vertical transmission of the virus from mother to child is being discussed. The aim of our study was to study the features of the period of postnatal adaptation of newborns born to mothers with coronavirus infection SARS-CoV-2 (COVID-19), taking into account the time of infection occurrence. We analyzed the features of the neonatal course in children from the mothers with confirmed Covid-19 infection (PCR RNA of SARS-Cov 2) revealed in the mothers either during pregnancy or in the postpartum period. When examining children, we used clinical, laboratory, and biochemical research methods. It was found that children whose mothers contracted coronavirus infection COVID-19 immediately before childbirth had an aggravated course of the neonatal period compared with children from mothers who had recovered in the middle of pregnancy, and the manifestations of infection and post-hypoxic syndrome were more pronounced in the former. Laboratory investigations proved that newborns from the mothers who fell ill shortly before childbirth had acute viral inflammation.
