and then there is this:
Hygiene refers to acts that can lead to good health and cleanliness, such as frequent handwashing, face washing, and bathing with soap and water. Keeping hands clean is one of the most important ways to prevent the spread of infection and illness. However, in many areas of the world, practicing personal hygiene is difficult due to lack of resources such as clean water and soap. Many diseases (including diarrheal diseases) can be spread when hands, face, and body are not washed appropriately at the key times.
one of the outreach works we did in Africa 40 years ago was to provide (shallow) wells for villages, so that during the dry season moms did not have to walk a mile to get water.
of course, to have safe drinking water, you need a filter or a deep well.
But that is another story...
