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.

П роблема острых средних отитов (ОСО) у детей сохраняет свою актуальность и активно изуча-ется во всех странах мира ввиду стабильно высокой распространенности и отсутствия тенденции к ее снижению. По данным различных авторов, на первом году жизни частота развития ОСО варьирует в широком диапазоне от 21 до 62% [1].Диагностика заболевания в этом возрасте представ-ляет трудную задачу. В значительной степени это связано с малосимптомностью, стертостью клинических проявле-ний болезни, высокой частотой сопутствующей патологии, маскирующей картину воспаления среднего уха. Особую опасность представляют собой ОСО у новорожденных и детей первых месяцев жизни, поскольку в этот возраст-ной период закладываются основы для формирования здорового организма, а младенцы в силу незрелости защитных механизмов наиболее уязвимы перед действи-ем патогенов. В силу указанных причин формирование групп риска развития воспаления среднего уха у детей первых месяцев жизни на основе выявления и стратифи-кации факторов, способствующих заболеванию, пред-ставляет собой важное направление современной педи-атрии. Знание факторов риска имеет смысл использовать как в диагностике, так и в профилактике заболевания.В литературе достаточно много внимания уделяется анатомо-физиологическим особенностям, предрасполага-ющим к развитию ОСО в данной возрастной группе: кра-нио-фациальному дисморфизму, возрастным особенно- Results. In the pregravid health status of the mother the most significant in terms of the risk of developing of otitis media in children in the first months of life are the presence of respiratory allergy (OR = 7,74; P = 0,014) and chronic infections of ENT organs (OR = 1,15; P = 0,022). In the prenatal period the risk of early manifestations of the first episode of otitis media in a child increases obesity during pregnancy (OR = 11,78, p<0,000), waterless period of more than 8 hours (OR = 8,60, p<0,000), TORCH and urogenital infections in the mother (OR = 7,29, P = 0,028). Formula (OR = 4,20, p = 0,004) and mixed (P = 0,008) feeding in the postnatal period and the male sex (58,6%) of the child are also associated with an increased risk of developing otitis media. For this age group otitis media was characterized by a high association with ARI (99,1%). Conclusion. We have identified risk factors of otitis media in infants and children during the first months of life allow us to form a high-risk group for development of this disease.
