Which of the following infections is estimated to be among the top five causes of death for adolescents aged 10-14 years?

• A. Diarrhea
• B. Pneumonia
• C. Measles
• D. Tuberculosis

Answer: (B)

Pneumonia is estimated to be among the top five causes of death for adolescents aged 10-14 years due to its significant impact on health, particularly in regions where access to healthcare is limited. Pneumonia can arise from various infectious agents, including bacteria, viruses, and fungi, and is especially critical for young children and adolescents who may have developing immunities. In this age group, pneumonia can lead to severe respiratory distress and complications, highlighting its importance as a public health concern.

Diarrhea, measles, and tuberculosis are also serious infectious diseases, but their prevalence and direct impact as leading causes of death have differed over time and across regions compared to pneumonia. For instance, while diarrhea-related diseases are critical, improved sanitation and access to clean water have reduced their mortality rates. Similarly, measles has seen declining mortality rates due to widespread vaccination efforts. Tuberculosis remains a significant health issue globally, particularly in adults and those with compromised immune systems, but it does not rank as the leading cause of death in the 10-14 age group as pneumonia does. Thus, pneumonia stands out due to its relatively higher incidence in this specific age demographic, marking its position as a key health challenge.
