Mold: A growth of fungi.
How Pathogens Enter The Body
Alimentary canal (airborne).
Parenteral openings (direct and indirect).
Vector transmission (bites and scratches from
insects, animals, etc.).
Through mucous membranes. In mouth, nose, and
eyes (direct and indirect).

Must be enough of it to overcome immune
system.

pathogen.
The pathogen must pass through the correct
portal of entry.
Pathogen Control
Personal protective equipment.
Good preventive practices.
Engineering controls.
Administrative processes.
Healthy lifestyle.
Pathogen Control
Personal hygiene (proper hand washing is best
deterrent to infectious diseases).
Heating for one minute at or above 180º F. Will

Bacteria usually airborne.
Transmitted by airborne mist droplets or
particles.
Infectious, but treatable.
