What do standard precautions published by the CDC assume about human blood or body fluids?

Standard precautions from the CDC are grounded in the principle that human blood and certain body fluids should be regarded as potentially infectious. This assumption stems from the understanding that not all infectious diseases present visible symptoms, and infections can be present in otherwise healthy individuals. By treating all blood and body fluids as if they may be contaminated, nail technicians and other healthcare providers minimize the risk of disease transmission to themselves and others.

This approach is crucial in ensuring infection control practices are stringent and consistent regardless of the perceived status of a person's health or setting. Ignoring this principle may lead to significant health risks, as it could result in the improper handling of potentially contaminated materials, especially in environments where skin is being worked on or where cuts may occur. Hence, the emphasis on treating all blood and body fluids as potentially infectious is a vital aspect of maintaining safety and hygiene in medical and therapeutic practices.
