Bloodborne Pathogens 101: Key Terms You Should Know

Understanding bloodborne pathogens and their associated terminology is essential for maintaining a safe and healthy workplace, particularly in environments where employees may be exposed to blood or other bodily fluids. This guide provides an overview of key terms related to bloodborne pathogens, ensuring that individuals can effectively navigate the risks and preventive measures associated with these infectious microorganisms.

1. Bloodborne Pathogens

Bloodborne pathogens are microorganisms found in blood and certain other bodily fluids that can cause diseases when transmitted from an infected person to another individual. Common bloodborne pathogens include hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV).

2. Hepatitis B Virus (HBV)

HBV is a viral infection that attacks the liver and can lead to chronic hepatitis, cirrhosis, or liver cancer. It is highly infectious and can survive outside the body for extended periods.

3. Hepatitis C Virus (HCV)

HCV is another viral infection affecting the liver. Chronic HCV infection can lead to liver damage, cirrhosis, and an increased risk of liver cancer.

4. Human Immunodeficiency Virus (HIV)

HIV is the virus that causes acquired immunodeficiency syndrome (AIDS). It weakens the immune system, making the body susceptible to various infections and certain cancers.

5. Universal Precautions

Universal precautions are safety measures that treat all blood and bodily fluids as if they are infectious. This approach ensures consistent use of personal protective equipment (PPE) and infection control practices to prevent exposure.

6. Personal Protective Equipment (PPE)

PPE includes gloves, gowns, masks, and eye protection used to protect individuals from exposure to bloodborne pathogens. It is an essential component of infection control.

7. Exposure Control Plan

An exposure control plan is a written document that outlines an organization's strategies and procedures for protecting employees from exposure to bloodborne pathogens. It includes preventive measures, training, and incident response protocols.

8. Needlestick Injury

A needlestick injury occurs when a sharp object, such as a needle or syringe, punctures the skin. Needlestick injuries can result in the transmission of bloodborne pathogens.

9. Post-Exposure Prophylaxis (PEP)

PEP is a preventive treatment administered after potential exposure to bloodborne pathogens to reduce the risk of infection. It typically involves antiviral medications and must be initiated promptly.

10. Exposure Incident

An exposure incident refers to any situation where an individual is exposed to blood or other bodily fluids that may contain bloodborne pathogens. Prompt reporting and evaluation are essential in such cases.

11. Engineering Controls

Engineering controls are physical or mechanical devices, such as safety-engineered needles or sharps containers, designed to minimize the risk of exposure to bloodborne pathogens.

12. Work Practice Controls

Work practice controls are policies and procedures that employees follow to minimize the risk of exposure. Examples include safe needle practices and proper disposal of contaminated materials.

13. Occupational Exposure

Occupational exposure occurs when employees are at risk of coming into contact with blood or bodily fluids in the course of their work. Employers must implement measures to protect workers from occupational exposure.

14. Bloodborne Pathogen Training

Training provided to employees to educate them about the risks associated with bloodborne pathogens, preventive measures, and proper response to potential exposures. Training often includes bloodborne pathogen certification.

15. Biohazard

A biohazard is a substance that poses a potential risk to human health or the environment due to its biological nature. Blood and certain bodily fluids are considered biohazards due to their potential for carrying bloodborne pathogens.


Familiarizing oneself with these key terms related to bloodborne pathogens is a crucial step in creating a safe and informed workplace environment. By understanding the terminology and the risks associated with bloodborne pathogens, individuals can take proactive measures to protect themselves and others from potential exposure and infection. Additionally, compliance with workplace safety regulations is essential for maintaining a secure and healthy workplace for all.
