I think Rene you brought a real concern and that is issue with water. Well , I think that children do not need bath every single day, we were 7 and took bath once a week and were just fine. I think what is more important is what Ika said. Make sure that our children hands are clean. Maybe each of us can bring antibacterial liquid to wipe their hands often. Also, let us now start taking sugar out of their diet so they have a good immunity. As far as adults I think we can still remember how to take a quick shower and we can train our spouses to do the same for just few days. I think we all are tolerant it can all work just fine.
