Objective: To describe the epidemiology of invasive and non-invasive pneumococcal disease during a 5-year period in a major hospital in Bahrain.   Design and Setting: Retrospective study of cases of pneumococcal diseases among patient ≥ 14 years old during a five-year period (2010-2014), who attended Salmaniya Medical Complex, Bahrain.   Patients and Methods: Laboratory data was obtained on Streptococcus pneumoniae isolates. Patients ≥14 years old of age, both inpatient and outpatient with cultures positive for Streptococcus pneumoniae were included. Only samples from blood, cerebrospinal fluid (CSF), pleural fluid, sputum, deep tracheal aspirate (DTA), bronchial wash, eye discharge and middle ear fluid were included. Demographics and clinical records from medical files were then reviewed.   Results: A total of 130 culture samples met the inclusion criteria and were analyzed. One-hundred twenty-six patients with pneumococcal disease were identified; with 65% being non-invasive and 35% being invasive pneumococcal disease. Overall, non-bacteremic Pneumonia was the most frequent manifestation, followed by bacteremia. Pneumococcal disease was more common among male patients (62.7%). Mean age was 57.67 (15-95 years). The most common comorbidities were hypertension, Diabetes Mellitus followed by cardiovascular disease. Twenty-seven patients received mechanical ventilation during their admission, 13 patients were admitted to the intensive care unit, and 6 patients developed para-pneumonic effusion as a complication. In-hospital Mortality rate was 13.5%.     Conclusion:  This study supports the current literature where pneumococcal infection is more prevalent in elderly and those with comorbidities. Mortality was related to age, certain chronic medical illness, admission to intensive care unit and need for mechanical ventilation.
