In the sanitary statistics stage, what environmental issue was highlighted?

• A. Chronic disease risk factors
• B. Vector-borne disease
• C. Poisoning by soil, air, water
• D. Germ theory

Answer: (C)

The key idea here is how public health began tying illness to the environment created by sanitation conditions. In the sanitary statistics stage, the emphasis is on data showing how people were harmed by environmental exposures, especially contamination of water, air, and soil. This is why poisoning by soil, air, and water stands out: it captures the environmental toxins and pollutants that drove disease burden and outbreaks, guiding reforms like clean water, proper waste disposal, and efforts to reduce air and soil contamination.

Chronic disease risk factors describe modern, lifestyle-related contributors to noncommunicable diseases rather than the environmental contamination focus of this stage. Vector-borne disease centers on diseases transmitted by vectors such as mosquitoes and ticks, which isn’t the core environmental exposure highlighted in sanitary statistics. Germ theory explains that microbes cause disease, a foundational concept that underpins medicine and public health but doesn’t emphasize the environmental poisoning aspect that this stage specifically spotlighted.
