What effect have antibiotics had on death rates from infectious disease?

• A. They have greatly reduced death rates.
• B. They have slightly increased death rates.
• C. They have no effect.
• D. They eliminated all infectious diseases.

Answer: (A)

Antibiotics dramatically cut deaths from infectious disease by turning many lethal bacterial infections into treatable conditions. Before antibiotics, illnesses like pneumonia, sepsis, meningitis, and tuberculosis caused high mortality. Once antibiotics became available, these infections could be cured or controlled with drugs, so death rates dropped by a large margin across the population. This profound improvement isn’t because all infectious diseases disappeared—viral infections and some resistant bacteria still pose challenges—but the overall mortality from bacterial infections fell dramatically thanks to antibiotics.
