The burden of pneumonia in children in Latin America

Area of Science:

• Global Health
• Pediatrics
• Epidemiology

Background:

• Under-five mortality rates exhibit significant international disparities, with acute respiratory infections (ARIs) being a major cause of death.
• The World Summit for Children aimed for a two-thirds reduction in global child mortality by 2015, but progress has been uneven.
• In 2000, developing countries accounted for 70% of the 1.89 million under-five deaths from ARIs.

Purpose of the Study:

• To analyze under-five mortality trends, particularly those related to acute respiratory infections, in Latin American countries.
• To identify disparities in mortality rates within the region and assess progress towards global child survival goals.
• To recommend effective interventions for reducing under-five mortality in Latin America.

Main Methods:

• Analysis of under-five mortality data across different countries and regions.
• Examination of the proportion of deaths attributed to acute respiratory infections.
• Review of regional variations in mortality rates, with a focus on Latin America.

Main Results:

• Under-five mortality rates range widely, from 4 to over 300 deaths per 1000 live births globally.
• Latin American countries show varied mortality percentages due to ARIs, with Chile and Uruguay at 5-10% and Bolivia, Peru, and Guyana at 15-20%.
• While mortality rates from lower respiratory infections have declined in many areas, they remain high in others.

Conclusions:

• Effective interventions are essential to achieve the 2015 goal of reducing under-five mortality.
• Key interventions include promoting breastfeeding and complementary feeding, Haemophilus influenzae type B vaccination, zinc supplementation, and antibiotic treatment for pneumonia.
• Universal implementation of these strategies across all Latin American countries is necessary to significantly decrease child mortality.
