    On October 15, 2008, the world first celebrated Global Handwashing Day. According to the Centers for Disease Control, “Good hand hygiene is one of the most critical control strategies in outbreak management.” 
    Handwashing can reduce outbreaks of dysentery and pneumonia, the two most common causes of child mortality around the world. Handwashing can also reduce the spread of the cold, flu, and illnesses caused by exposure to harmful chemicals, bacteria, viruses, and dirt.
    One of the most effective ways to promote good “hand hygiene” is the tippy tap. The tippy tap is a simple, affordable, and ingenious way to reach communities in the developing world who live in rural areas where there is limited running water.
    The tippy tap is a device that uses inexpensive and widely available materials (such as sticks or poles), a jug of water, and soap. It is easily constructed and operated by a foot lever, which reduces the chances of transmitting bacteria on the device. Communities in India, Uganda, the Dominican Republic, Kenya, Laos, South Sudan, Ecuador, and Haiti have established tippy taps to promote good hand hygiene and reduce deadly disease outbreaks.
