Epidemic problems in major cities occurred during which century?

• A. 18th Century
• B. 19th Century
• C. 17th Century
• D. 20th Century

Answer: (B)

Urban epidemics in major cities arose prominently in the 19th century as cities expanded rapidly but sanitation lagged behind. The rapid growth of urban populations created crowded living conditions and contaminated water supplies, which fueled outbreaks of diseases like cholera that struck big cities hardest. A key moment was the London cholera outbreak of 1854, where John Snow linked transmission to a contaminated water pump, demonstrating a waterborne cause and triggering public health reforms. This led to the building of modern sewer systems and broader sanitation improvements, marking the rise of organized urban public health measures. With these advancements, the frequency and impact of epidemics in large cities diminished as the century progressed and into the 20th century. While earlier centuries had outbreaks, they did not pattern as strongly across major cities in the same way, and the 20th century saw further reductions due to vaccines and public health infrastructure.
