ABSTRACT=<p><bold>Objectives:</bold> There are limited data on the impact of the COVID-19 outbreak in Poland on newborn health. The aim of the study is to show recent information on hospitalizations of newborns in Poland in the pre-pandemic and COVID-19 pandemic era.</p><p><bold>Methods:</bold> A retrospective, population-based study was conducted using data from hospital discharge records of patients hospitalized in 2017–2021.</p><p><bold>Results:</bold> The data on which the study was based consisted of a substantial number of 104,450 hospitalization records. Annual hospitalization rate was estimated to be 50.3–51.9 per 1,000 in 2017–2019, 56 per 1,000 in 2020 and it rose to 77.7 per 1,000 in 2021. In comparison to the pre-pandemic period, in the COVID-19 era, we observed significantly more hospitalization cases of newborns affected by maternal renal and urinary tract diseases (<italic>p</italic> &lt; 0.001), syndrome of infant of mother with gestational diabetes (<italic>p</italic> &lt; 0.001), maternal complications of pregnancy (<italic>p</italic> &lt; 0.001). In the COVID-19 era, the prevalence of COVID-19 among newborns was 4.5 cases per 1,000 newborn hospitalizations.</p><p><bold>Conclusion:</bold> The COVID-19 pandemic outbreak could significantly contribute to qualitative and quantitative changes in hospitalizations among newborns.</p>
