The aim: To characterize the course of the most common perinatal infections on the basis of assessment of the literature data. Materials and methods: This article provides an assessment of 125 literature sources submitted to PubMed, Medline, Cochrane Library, CyberLeninka, Google Scholar and V.I. Vernadsky National Library of Ukraine. The description of the most common viral, bacterial and parasitic perinatal infections, transmission methods, clinical manifestations, methods of diagnosis and treatment, their clinical consequences are described. Perinatal infections are the leading cause of severe congenital pathology, a serious worldwide medical and social problem that needs to be addressed. Conclusions: Perinatal infections are a serious issue of today, requiring a multidisciplinary approach and the collaboration of doctors of different specialties. Their prevalence among the population, high rates of perinatal mortality, concealment under the mask of other disorders, and the absence of specific clinical symptoms in pregnant and newborns require careful consideration of this problem. Improving the quality of diagnosis and treatment of this pathological condition will help to minimize the risk of transmission of infection, as well as to avoid a number of abnormaalities in the neonatal period and the development of congenital infection.

The aim: According to the literature sources to summarize statistics on the prevalence of intrauterine infection and its impact on pregnancy and the condition of newborns at the present stage. Materials and methods: The article analyzes 35 literature sources (scientific publications) from 2000 to 2021, indexed in international scientometric database and covers the incidence of intrauterine infections in countries with different income levels, as well as their impact on pregnancy, childbirth and the condition of newborns. Conclusions: The main task of obstetrics and gynecology at the present stage is to reduce reproductive losses, which necessitates further study of the etiology of IUI, especially in low- and middle-income countries. The screening for IUIs during pregnancy is cost-effective because treatment of the effects of IUIs requires disproportionately greater resources.
