The New York Times on how Dr Val Cur­tis ‘sold’ hand-washing to Africa:

Dis­eases and dis­or­ders caused by dirty hands — like diar­rhoea — kill a child some­where in the world about every 15 sec­onds, and about half those deaths could be pre­vented with the reg­u­lar use of soap, stud­ies indicate.

But get­ting peo­ple into a soap habit, it turns out, is sur­pris­ingly hard.

To over­come this hur­dle, Dr. Cur­tis called on three top con­sumer goods com­pa­nies to find out how to sell hand-washing the same way they sell Speed Stick deodor­ant and Pringles potato chips.
