• I gather that the reason to be careful is not just to avoid illness, but to protect the most vulnerable and not slam the healthcare system all at once.
• because of toxicity of even microscopic amounts of feces (and nonhealthy urine) and spread of disease from and in them.
• I read in news that feces are found in dift parts of bathrooms (splatter travels from one thing 2 another it would seem, like at least 6 feet)
• crotches/pelvises probably always have microscopic feces, even when they seem to have been cleaned (because of imperfection in cleaning, gas, living & moving)
• It is important that children learn good habits and that adults model them, for the health benefit of themselves and the future generations.
