Which set of health issues is central to life in low-income nations according to the material?

• A. Noncommunicable diseases
• B. Infectious diseases, high infant mortality, scarce medical personnel, and inadequate water and sanitation
• C. Mental health disorders
• D. Injuries from accidents

Answer: (B)

In low-income nations, the health landscape is shaped by a heavy burden of infectious diseases and weak health systems. Infectious diseases are a major driver of illness and death because prevention, vaccination, diagnosis, and treatment options are often limited. High infant mortality arises from gaps in prenatal and postnatal care, malnutrition, and vulnerable living conditions, all of which are linked to broader resource constraints. Scarcity of medical personnel and health facilities means fewer doctors, nurses, and midwives to reach rural communities and provide essential services like immunizations, maternal care, and timely treatment. Inadequate water and sanitation further amplify disease transmission, especially diarrheal illnesses, which disproportionately affect children and contribute to overall health declines. While other health issues exist, this combination—infectious disease burden, weak care capacity, and poor WASH infrastructure—best captures the central health challenges described for life in low-income nations.
