neoplasms new or abnormal growths
psychiatric mental disorders
endogenous source of microorganism is within our cells
exogenous source of microorganism comes from environment
toxigenic diseases eating food with toxins and poisons produced by microorganisms in great numbers
incubation stage or period from the initial entrance of the infectious agent into the body
prodromal when signs and symptoms begin to show → few microorganisms are present
acute when the most amount of microorganisms are present
convalescent the amount of organisms begin to decrease
step (2) escape of microorganism from the source portal of exit from reservoir
step (1) source/reservoir of microorganism source or reservoir is where the microorganisms are growing
step (3) spread of microorganism once a microorganism has escaped, it can spread to others
direct contact direct contact with the source
indirect contact contact with surfaces or objects that are contaminated with microorganisms
droplet infection visible drops greater than 5 µm (micrometers) of body fluids are expelled into the air and settle out quickly → droplets drop because they’re bigger transmitted by close contact
airborne infection droplet nucleic or aerosol particles that are smaller than 10 µm in diameter can remain airborne for hours
step (4) portal of entry 4 basic routes (inhalation, ingestion, mucous membranes, broken skin
step (5) infection multiplication and survival of microorganisms on or in our body
step (6) damage to body involve a battle between the infecting organism and the defence of the body
