Health experts recommend handwashing with soap as a key action in protecting the public health because it’s a mainstay in infection control. Are we really following their advice?
People worldwide rinse their hands with water in the common belief that rinsing with water alone suffices to clean hands because it removes visible dirt. But rinsing hands with water alone is significantly less effective for removing germs than washing hands with soap. Handwashing with soap is seldom practiced, however.
Research reveals that the observed rates of handwashing with soap at critical times (after using the toilet or cleaning a child’s bottom and before handling food) around the world, in industrialized and developing nations, ranges from zero to 34 percent.
Low rates of handwashing are rarely caused by a lack of soap. Soap is present in the vast majority of households worldwide, but it is commonly used for bathing and laundry, not for handwashing. Lack of water is usually not a problem either, as hands can be effectively washed with little, or recycled water. In studies around the world, one major reason for low rates of handwashing with soap is that this is simply not a habit.
The challenge remains: make handwashing with soap a worldwide habit and social norm.
To successfully promote the practice of handwashing with soap, public and private sector partners are drawing on their comparative strengths, resources, and best practices to create effective, large scale, and sustainable handwashing promotion programs.
By bringing the lessons learned in social and commercial marketing to hygiene programming, the PPPHW aims to catalyze effective, sustainable changes in handwashing behavior on a large scale.
Ministries of Health, Education, Water, and non-governmental organizations (NGOs), the private sector, and community-based groups must all use every opportunity to promote handwashing with soap, based on the lessons learned.
Research shows that handwashing behavior tends to stick once individuals and families have adopted the practice. However, bringing about large-scale handwashing behavior change remains a challenge.
Behavioral research from several developing countries shows that people are often motivated to wash their hands with soap by factors other than health, such as disgust, or a wish to be seen as a good parent, to appear attractive, or to protect and nurture children. Additionally, the presence of a handwashing facility is critical in getting people to wash their hands.
