Bloodborne Pathogen Overview

Posted on: January 21st, 2011 by Sheree Wertz, RDH, BS


Bloodborne Pathogens a quick overview:
 
 

What are bloodborne pathogens?
 

Bloodborne Pathogens are bacteria and viruses present in blood and body fluids that can cause disease in humans.  

Bloodborne pathogens are spread through:

 - direct contact

 - indirect contact

 - droplet transmission

 - vector-borne transmission

  Diseases of primary concern:

- Hepatitis B

- Hepatitis C 

- HIV

How are bloodborne pathogens transmitted? 

Direct contact:  Occurs when infected blood or body fluids from one person enter another person’s body at a entry site.  


Indirect contact: 
 Occurs when a person touches an object that contains the blood or body fluid of an infected person, and that infected blood or body fluid enters the body at a entry site.


Droplet transmission: 
 Occurs when a person inhales droplets from an infected person’s cough or sneeze.


Vector-borne transmission:
Occurs when the body’s skin is penetrated by an infectious source.
   
 


Four conditions must be met for transmission:
 

- A pathogen is present.

- There is enough of the pathogen present to cause disease.

- A person is susceptible to the pathogen.

- The pathogen passes through the correct entry site.    


Remember this is all preventable with Universal /  Standard precautions.
 
 

Universal / Standard precautions you should take while providing care include:  

- Avoiding contact with blood and other body fluids.  

- Using personal protective equipment, such as disposable gloves, protective eyewear, protective footwear, gowns and breathing barriers.  

- Using safer equipment such as self-sheathing needles, needleless systems or sharps with engineered sharps protection. 

- Placing sharps in proper containers.

- Cleaning and disinfecting all possibly contaminated work surfaces and equipment after each use. 

 - Avoiding touching your eyes, mouth and nose while providing care or when exposure to infectious materials is possible.  

 - Avoid eating drinking, smoking, applying cosmetics or lip balm, or handling contact lenses while providing care or when exposure to infectious materials is possible.  

- Thoroughly washing your hands with soap and warm water or other disinfectant products immediately after providing care, even if you are using disposable gloves.  

- Use alcohol based rubs where handwashing facilities are not available.  

- Remove/dispose of soiled protective clothing as soon as possible.  

- Disposing of contaminated materials in appropriate receptacles 

Exposure procedures:

Exposure incidents involve contact with blood or other potentially infectious materials.


If there is an exposure:

- Clean the area of contact.

- Write down what happened.

- Notify your supervisor.

- Seek medical attention.

- Follow your facility’s post-exposure policies and procedures.
