This statement is incorrect. Standard precautions should be followed for all body fluids, including saliva and tears. Standard precautions are a set of infection control practices to prevent the transmission of infections and diseases in healthcare settings. It includes the use of personal protective equipment (such as gloves, masks, and gowns) and proper hand hygiene. Saliva and tears can potentially contain infectious agents, and therefore, standard precautions should be used when in contact with these fluids.
