If you work in health care how do you deal with patients that have aids or hiv? what special precautions?

Universal precaution: All healthcare workers should be familiar with universal precautions. That is, treat every patient as though they are infected with HIV or hepatitis. If you obey that rule, then you don't have to take any special precautions. You always wear gloves when handling anything that could have body fluids on it, all sharps go in a sharp container regardless if it is from a newborn or a prostitute etc.
