Can certain blood-borne pathogens, such as Human Immunodeficiency Virus (HIV) or Hepatitis B Virus (HBV), be transmitted through skin-to-skin contact?

From the Guidelines

False. Blood-borne pathogens, by definition, are infectious microorganisms present in blood that can cause disease in humans. These pathogens typically require direct contact with infected blood or certain body fluids to be transmitted, not merely skin-to-skin contact. Common blood-borne pathogens include Hepatitis B virus (HBV), Hepatitis C virus (HCV), and Human Immunodeficiency Virus (HIV). For transmission to occur, these pathogens need a direct route into the bloodstream, such as through open cuts, sores, or mucous membranes. Intact skin provides an effective barrier against these pathogens. This is why healthcare workers use personal protective equipment like gloves when handling blood or body fluids, and why protocols for needlestick injuries and blood exposure are so important. It's worth noting that some pathogens can be transmitted through skin-to-skin contact, but these are not classified as blood-borne pathogens; they include organisms that cause conditions like scabies, ringworm, or herpes.

According to the most recent and highest quality study available, 1, persons with HBsAg should be advised to cover cuts and skin lesions to prevent spread by infectious secretions or blood, but this does not imply that skin-to-skin contact can transmit blood-borne pathogens. The key factor in transmission is the presence of an open wound or mucous membrane exposure, as stated in 1.

Some key points to consider:

• Blood-borne pathogens require a direct route into the bloodstream to cause infection, such as through open cuts, sores, or mucous membranes 1.
• Intact skin provides an effective barrier against blood-borne pathogens 1.
• Healthcare workers use personal protective equipment like gloves when handling blood or body fluids to prevent transmission 1.
• Protocols for needlestick injuries and blood exposure are crucial in preventing the transmission of blood-borne pathogens 1.

In summary, blood-borne pathogens cannot be transmitted through skin-to-skin contact alone, and require a direct route into the bloodstream to cause infection.

From the FDA Drug Label

In all exposures, a regimen combining Hepatitis B Immune Globulin (Human) with hepatitis B vaccine will provide both short- and long-term protection, will be less costly than the two-dose Hepatitis B Immune Globulin (Human) treatment alone, and is the treatment of choice. For inadvertent percutaneous exposure, a regimen of two doses of Hepatitis B Immune Globulin (Human), one given after exposure and one a month later, is about 75% effective in preventing hepatitis B in this setting. For an infant with perinatal exposure to an HBsAg-positive and HBeAg-positive mother, a regimen combining one dose of Hepatitis B Immune Globulin (Human) at birth with the hepatitis B vaccine series started soon after birth is 85%–95% effective in preventing development of the HBV carrier state.

The statement that certain blood borne pathogens can be transmitted simply by having skin to skin contact is False. The text only mentions transmission through:

• Parenteral exposure (e.g. needlestick)
• Direct mucous membrane contact (e.g. accidental splash)
• Oral ingestion (e.g. pipetting accident)
• Perinatal exposure from mother to infant
• Sexual exposure There is no mention of skin to skin contact as a mode of transmission. 2

From the Research

Blood Borne Pathogen Transmission

• The statement that certain blood borne pathogens can be transmitted simply by having skin to skin contact is false.
• According to the studies, blood borne pathogens such as HBV, HCV, and HIV are transmitted through blood and other body fluids, not through skin to skin contact 3, 4, 5, 6.
• The risk of transmission of these pathogens can be reduced by using personal protective equipment, improving engineering controls, and developing better work practices 6.
• Postexposure prophylaxis is an important consideration for preventing the transmission of blood borne pathogens, and it involves the use of vaccines, immune globulin, and antiviral agents 3, 4.
• The management of exposure to blood borne pathogens requires a detailed risk assessment and the use of appropriate preventive measures, including vaccination and antiviral therapy 4, 5.
