Streptococcus pneumoniae is a common infectious agent responsible for pneumonia, which can result in serious complications such as meningitis, sepsis, morbidity, and mortality. The objective of this study is to examine the risk factors and complications associated with mortality caused by community-acquired pneumococcal pneumonia in both adults and children. To conduct this research, a thorough literature review was carried out by researchers between May 1, 2021, and August 1, 2021. Various databases, including PubMed, WHO, clinicaltrials.gov, Embase, Web of Science, Cochrane, and Google Scholar, were searched using specific keywords such as mortality, pneumococcal pneumonia, adults, children, and their combinations. The study encompassed patients of all age groups affected by pneumococcal pneumonia, while systematic reviews focusing on other types of pneumonia and non-pneumonia patients were excluded. After eliminating duplicate studies, the search yielded 1783 relevant articles, which underwent title and abstract screening. Ultimately, 8 studies were included in the final review. In conclusion, pneumococcal pneumonia is a significant contributor to mortality among both adults and children. This research emphasizes the importance of implementing effective management strategies to reduce long-term mortality
