How long do pathogens live?

The survivability of the pathogen depends on its type. Some pathogens will live for a few minutes to hours, while others may survive for a few days, outside of a host.

How are pathogens transmitted?

Some pathogens are transmitted directly through blood. These pathogens require that infected blood from the reservoir be directly exposed to the blood of the susceptible host. This can be accomplished by blood from a needlestick and blood entering mucous membranes or other open wounds.

What is the mode of transmission of pathogens?

Mode of Transmission: Airborne. Airborne transmission occurs when pathogens smaller than five microns in size remain suspended in the air long after the infected person has left the area. A host then enters the space where the pathogen is suspended and has the potential to become infected.
