Which work activity increases the risk of hookworm infection?

1. Using protective footwear

2. Working in an air-conditioned environment

3. Walking barefoot in soil

4. Performing indoor office work

The correct answer is: Walking barefoot in soil

Walking barefoot in soil significantly increases the risk of hookworm infection because hookworms are parasitic worms that typically penetrate the skin, usually through bare feet. These parasites are commonly found in contaminated soil, particularly in warm, moist climates. When someone walks barefoot in such environments, the larvae can enter the body, leading to infection. In contrast, using protective footwear can effectively prevent direct contact with contaminated soil, while working in an air-conditioned environment or performing indoor office work generally minimizes exposure to the natural environment where hookworms thrive. Thus, the choice of walking barefoot in soil clearly poses the highest risk for hookworm infection.
