Invasive Pneumococcal Disease and Risk Factors

Paediatrics

Invasive pneumococcal disease (IPD), caused by Streptococcus pneumoniae, includes serious infections such as bacteraemia, meningitis, and bacteraemic pneumonia. The risk is higher in young children, older adults, and individuals with underlying conditions such as immunodeficiency, functional or anatomical asplenia, chronic cardiopulmonary disease, diabetes, and chronic kidney or liver disease. Clinical presentation may vary, making early recognition, appropriate microbiological testing, and timely antibiotic treatment essential. Understanding host-related risk factors and pneumococcal serotype patterns can help identify vulnerable populations. Preventive strategies include age- and risk-appropriate pneumococcal vaccination, management of comorbidities, and surveillance of antimicrobial resistance to reduce disease burden and improve clinical outcomes.
