Which parts of the body should never be touched?

The touch of the anus is one of the most important ways of transmitting germs, and even the bacteria "E coli" (a bacterium that can cause nausea, diarrhea and even diarrhea). Scientists say the touch of the anus helps ease the transfer of natural gastrointestinal organs through the hands. Direct or indirect contact with the eyes and mouth causes infections in these areas.
