In Iran even very young children are learned to wash their hand with liquid soap after using the bathroom and not doing that is highly regarded non-hygienic. In Iran, there is a water tap beside the toilet and there is no hand contact with feces or urine.
Disturbingly, a friend of mine who lives in a hostel in Sydney told me that none of his roommates wash their hands or even use a toilet papers. Her roommates are from various continents. (There are even hand washing denialists )
Is there any statistics about the issue in various countries
