Blood borne Pathogens quick facts
Blood borne
Pathogens are bacteria and viruses present in blood and body fluids that
can cause disease in humans.
Diseases of
primary concern are Hepatitis B, Hepatitis C and HIV.
Bloodborne
pathogens are spread through direct contact, indirect contact, droplet
transmission and vector-borne transmission.
Direct contact occurs when infected blood
or body fluids from one person enter another person’s body at a correct
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 correct 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.
