Control of infectious intestinal diseases requires which factor?

The control of infectious intestinal diseases is a multifaceted challenge that requires a comprehensive approach, which is why the correct answer encompasses all the listed factors.

Provision of safe water supplies is crucial because contaminated drinking water can be a significant source of pathogens that cause intestinal diseases. Ensuring that water is free from contaminants reduces the risk of infection and helps protect public health.

Proper waste disposal is equally important as it prevents the spread of pathogens through environmental contamination. When waste is not disposed of correctly, it can contaminate soil and water sources, leading to a higher incidence of infectious diseases.

Personal hygiene plays a critical role as well. Practices such as regular handwashing, particularly after using the restroom or before handling food, significantly reduce the transmission of pathogens. Good hygiene practices help to break the chain of infection at an individual level.

Considering these factors collectively demonstrates that a holistic approach involving safe water, waste management, and personal hygiene is essential for effectively managing and controlling infectious intestinal diseases. Thus, the answer includes all these vital components.
