Your mouth contains more bacteria than any other part of your body, including the anus or intestines. Whilst speaking (let alone coughing or sneezing) you constantly spray a fine mist of saliva containing your own DNA, bacteria, and particles of whatever has recently been in your mouth - this spray settles on surfaces (such as the clothes and skin of the person you are talking to) and leaves a forensically detectable residue. The bacteria living in your mouth are capable of making other people very ill, which is one of the reasons that a tetanus jab is administered in cases where someone has been bitten (whether by an animal such as a dog, or by a human) - to fight the potentially flesh-eating infection that could result.
