INTRODUCTION
Overview
Bloodborne pathogens are an ever existing threat for medical workers. It is important for anyone involved in medical care to familiarize themselves with ways of protecting themselves from said threat.
This topic provides an overview on common bloodborne pathogens and biological hazards in the healthcare setting, based on OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030). [1] Upon reading this topic, healthcare professionals will learn the following:
- Define bloodborne pathogens and biological hazards.
- Identify common bloodborne pathogens and their transmission routes.
- Understand the importance of infection control measures.
- Learn strategies for preventing exposure to bloodborne pathogens and other biological hazards.
- Know how to respond in case of exposure incidents.
For exposure to bloodborne pathogens due to needlestick injuries see topic "Exposure to Bloodborne Pathogens and Needlestick Injuries".
Background
Definition
- Bloodborne pathogens are infectious microorganisms that can cause disease in humans. [2]
- The following are common examples of pathogens:
- Hepatitis B (HBV)
- Hepatitis C (HCV)
- Human Immunodeficiency Virus (HIV)
BLOODBORNE PATHOGENS
Routes and Transmission
The following are the common means by which bloodborne pathogens are transmitted [3]: - Accidental puncture from contaminated needles, broken glass, or other sharps
- Contact between broken or damaged skin and infected body fluids (e.g. open wounds, wound exudate)
- Contact between mucous membranes and infected body fluids
- Sexual Contact
- Sharing of hypodermic needles
- From mothers to their babies at/before birth
Preventing Exposure
Occupational hazards have been traditionally controlled in terms of a hierarchy and presented in order of priority. Below are the controls to prevent needle-stick injuries and other blood exposures:
- Elimination of Hazard
- Refers to the complete removal of a hazard from the work area as the most effective way to control hazards.
- Engineering controls
- These are used to isolate or remove a hazard from a workplace
- Administrative Controls
- These are policies, such as SOPS, which aim to limit exposure to the hazard.
- Work Practice Controls
- These are controls to change the behavior of workers, and reduce exposure to occupational hazards
- Personal Protective Equipment
- These are controls to change the behavior of workers, and reduce exposure to occupational hazards.
Infection Control Measures
The following are minimum infection preventive precautions taken by healthcare team members and staff at healthcare facilities to prevent the spread of infections as defined by the CDC
[4]:
- Hand hygiene, proper washing of hands before and after patient contact
- Use of appropriate protective equipment (i.e., gloves) before patient contact
- Respiratory hygiene (i.e., covering your cough and sneeze)
- Injection and sharp object safety and proper disposal
- Cleaning of supplies and disposal of waste
Responding to Bloodborne Pathogen Exposure
Should someone be exposed to Bloodborne Pathogens, the following should be done to immediately:
- In cases of cuts, wash needlesticks and cuts with soap and water.
- For splashes, immediately flush the splashed area (nose, mouth, or skin) with water.
- For exposure to the eyes, irrigate the eyes with clean water, saline, or sterile wash.
- Report all exposures promptly to ensure that you receive appropriate follow up care.
OTHER BIOLOGICAL HAZARDS
Various workplaces and industries have ways of dealing with different biohazards. The following are the common threat to health and safety of the workers
[5]:
- Animal Waste
- Human bodily matter
- Microbiological waste
- Pathological waste
- Sharp waste
- Molds and yeasts
- Organic material
- Airborne Pathogens
- Stinging insects

SUBTOPICS
Exposure to Bloodborne Pathogens and Needlestick InjuriesIntroductionNeedlestick and other sharps injuries are a serious hazard in any medical care situation. These injuries are caused by different types of needles and sharps, such as scalpels and broken glass containers. Contaminated nee- dles and sharps may inject healthcare work- ers with blood that contains pathogens such as hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV), all of

Musculoskeletal Disorders and Ergonomic InterventionsIntroductionAll healthcare workers who lift and move patients are at high risk for back injury and other musculoskeletal disorders [Owen 1999; Waters et al. 2006]. A work-related musculoskeletal disorder is an injury of the muscles, tendons, ligaments, nerves, joints, cartilage, bones, or blood vessels in the extremities or back that is caused or aggravated by work tasks such as lifting, pushing, and pulling [Orr 1997]
Occupational StressIntroductionHome healthcare work involves challenges that are not present in hospital or other in- patient healthcare settings. Not many stud- ies have looked into stress levels of home healthcare workers, but the few studies that have show that home healthcare may be quite stressful. The home setting may in- volve stressors, such as lack of control over work planning, that are risks for shoulder and neck pain, especially when combined with physical risk f
Violence in The WorkplaceIntroductionServing patients in the community is the essence of home healthcare. Yet, the com- munity setting makes home healthcare pro- viders more vulnerable to violent assaults. Home healthcare workers face an unpro- tected and unpredictable environment each time they enter the patient’s community and home. According to estimates of the Survey of Occupational Injuries and Illnesses (SOII) [BLS 2007a], 330 nonfatal assaults on home healt
Exposure to Other Hazards7.1 Introduction
Handling Medical WasteOverviewHealthcare settings, including hospitals, doctor's offices, dental clinics, blood banks, veterinary clinics, and research labs, produce various kinds of medical waste. As someone working in healthcare, you might encounter these wastes directly in your role, whether you're involved in patient care, housekeeping, maintenance, or other tasks. It's important to note that some medical waste can pose health risks. This training aims to outline the potenti
