Which bodily fluid is excluded from standard precautions?

Standard precautions are guidelines designed to prevent the transmission of infectious diseases within healthcare settings. These precautions apply to all body fluids and substances with the exception of certain fluids that are typically not considered infectious.

Sweat is excluded from standard precautions because it is not known to carry infectious agents through casual contact. Unlike blood, saliva, and urine, which can potentially transmit pathogens through exposure, sweat does not pose a risk of disease transmission when handled in the context of standard precautions. Therefore, while care should always be taken with bodily fluids during medical procedures, sweat does not require the same protective measures as the others listed.
