I have not found any change in the Universal Precautions recommendation since
the 1988 publication by the CDC. Although I realize that books have a time
lag before publication, my pathophysiology text, copyright date 1994 uses the
same resource in the section about AIDS and Universal Precautions. Hepatitis
B and AIDS are spread under similar circumstances. Hepatitis B vaccine is
recommended as an adjunct to universal precautions for health care workers
who have exposure to blood.

The reference is
CDC: Update: Universal precautions for prevention of transmission of HIV,
Hepatitis B virus and other bloodborne pathogens in health-care settings.
Morbidity and Mortality Weekly Reports 37:378-87, 1988. (June 24, 1988)

Here is two quotes from this publication.

<Universal precautions do not apply to feces, nasal secretions, sputum,
sweat, tears, urine, and vomitus unless they contain visible blood. The risk
of transmission of HIV and HBV from these fluids and materials is extremely
low or nonexistent.>

<...occupational exposure to human breast milk has not been implicated in the
transmission of HIV nor HBV infection to health-care workers. Moreover, the
health-care worker will not have the same type of intensive exposure to
breast milk as the nursing neonate. Whereas universal precautions do not
apply to human breast milk, gloves may be worn by health-care workers in
situations where exposures to breast milk might be frequent, for example, in
breast milk banking.>

Gloves are part, but not all of the Universal Precautions procedure. Gloves
are part of aseptic procedures and provide protection from potential
infections to and from heath care workers. There are many reasons for wearing
gloves. It is good to think about what we are doing.

My job is not limited to lactation consulting. I wash my hands very
frequently, use lotion to prevent cracking, and glove when appropriate.
