There are tribes who follow the old ways, who very rarely contract insect born diseases. These people carry water miles from it's source, to their camps. "What a burden for those who carry the water," you say? The water bearers bathe, and drink their fill at the river's edge, before carrying the water spirit gift back to their families, where it is shared sparingly. There is always balance.
Before we adopt a practice intended to make life easier, we must carefully consider the cost to our human spirit.
