Clinical Burden of Invasive Pneumococcal Disease in Selected Developing Countries

Area of Science:

• Global Health
• Infectious Diseases
• Epidemiology

Background:

• Invasive pneumococcal disease (IPD) represents a substantial global health challenge.
• Developing countries often face a disproportionately high burden of infectious diseases due to various socioeconomic and healthcare factors.

Purpose of the Study:

• To quantify the clinical burden of invasive pneumococcal disease (IPD) in selected developing countries.
• To analyze the incidence and case-fatality ratios (CFR) of IPD across different regions.

Main Methods:

• An extensive literature review was conducted, analyzing published articles on IPD.
• Articles published between 2000 and 2010 from East Asia, South Asia, the Middle East, sub-Saharan Africa, and Latin America were included.
• Inclusion, exclusion, and quality criteria were applied to select relevant studies.

Main Results:

• Ten articles from ten developing countries were included, providing data on pneumococcal meningitis, septicemia/bacteremia, and pneumonia.
• IPD incidence ranged from less than 5/100,000 to 416/100,000 population.
• Case-fatality ratios (CFR) varied significantly, ranging from 12.2% to 80%.

Conclusions:

• The clinical burden of IPD is high in developing countries.
• IPD incidence and CFR exhibit considerable regional and national variation.
• The highest burden of IPD was observed in sub-Saharan African and South Asian countries, with lower CFRs reported in high-income countries compared to low-income nations.
