Early-onset sepsis (EOS) remains a major cause of neonatal morbidity and mortality worldwide, with significant differences in the incidence and outcome of the disease in Europe. Eastern European countries face particular challenges due to differences in access to healthcare, diagnostic facilities, and prevention strategies. This review summarizes the results of recent research to provide insights into maternal risk factors, regional inequalities in access to healthcare, diagnostic biomarkers, pathogen patterns, and treatment protocols for EOS. This review also examines how healthcare infrastructure and socioeconomic factors influence EOS outcomes in Eastern Europe. Introduction: Early-onset sepsis (EOS) presents a significant health challenge for newborns, characterized by sepsis occurring within the first 72 h of life, primarily caused by the vertical transmission of pathogens from mother to child. Despite advancements in medical care, EOS remains particularly burdensome in resource-poor settings, especially in Eastern Europe, where disparities in healthcare access and maternal health are pronounced. This systematic review aims to provide insights into maternal risk factors, regional inequalities in healthcare access, diagnostic biomarkers, pathogen patterns, and treatment protocols for EOS. Background/Objectives: EOS is increasingly recognized as a public health issue, with outcomes significantly influenced by maternal health, socioeconomic status, and healthcare infrastructure. The review seeks to summarize the existing literature on EOS, particularly focusing on differences between high-income Western and low-resource Eastern European countries. The influence of maternal access to antenatal care, pathogen prevalence, and antibiotic resistance on EOS outcomes across regions will also be examined. Methods: To achieve the review’s objectives, a comprehensive search was conducted across multiple databases including PubMed, Google Scholar, ScienceDirect, and Scopus, adhering to PRISMA guidelines for systematic reviews. The inclusion criteria encompassed studies published within the last 20 years (January 2004–August 2024) that addressed EOS in late preterm or term infants, emphasizing maternal health, risk factors, diagnostic approaches, and treatment protocols pertinent to European populations. Exclusion criteria included non-English publications and studies lacking a focus on maternal and neonatal health. A total of 29 peer-reviewed articles meeting the specified criteria were ultimately included in the analysis. Results: The findings highlight significant regional disparities in EOS management between Western and Eastern Europe. Key issues include maternal risk factors, socioeconomic barriers to healthcare, diagnostic biomarkers, and pathogen resistance trends. Limited access to prenatal screenings and healthcare infrastructure in Eastern European countries, especially in rural regions in Romania, exacerbate the challenges faced by expectant mothers. Financial burdens, such as high out-of-pocket expenses, were shown to further restrict access to necessary maternal care. Conclusions: This systematic review emphasizes the urgent need for targeted investments in maternal healthcare infrastructure in Eastern Europe to mitigate the impacts of EOS. Enhanced screening programs, standardized surveillance systems, and ensuring equitable health policies are essential to improving neonatal outcomes. Additionally, tailored education and awareness campaigns for disadvantaged groups and comprehensive health policy reforms, including universal antenatal care and Group B Streptococcus (GBS), are essential to bridging healthcare gaps.
