15. Infectious Diseases
The infectious disease process is defined as the
interaction between the pathogenic microorganism,
the environment, and the host.
16. The chain begins with the
existence of a specific pathogenic
microorganism.
The second link is the
reservoir, an
environment where
the pathogen can
survive.
17. The third link is the
means of escape from
the reservoir.
The fourth link is the mode
of transmission from the
reservoir to the host.
18. The fifth link is the means of
entry into the host.
And the last link is the
host's susceptibility to the
pathogenic
microorganism.
19. If even one link of the chain is missing, it
interrupts the process, and no infection will
occur.
