Which of the following is an essential element of WASH?

• A. Safe water.
• B. Hospital-based treatment.
• C. Nutritional counseling.
• D. Genetic screening.

Answer: (A)

WASH focuses on preventing disease through access to clean water, safe sanitation, and good hygiene practices. Safe water is the foundational element because it directly reduces exposure to waterborne pathogens that cause diarrheal diseases and other illnesses. When water quality and supply are secure, it supports effective handwashing, safer sanitation, and overall lower transmission of fecal-oral infections. Without safe water, the benefits of sanitation and hygiene are undermined.

Hospital-based treatment, nutritional counseling, and genetic screening are important health interventions, but they fall outside the public health prevention scope that WASH addresses.
