topic is necessary. The organisms of most
concern are M. tuberculosis, HIV, and Viral
Hepatitis. These are potentially pathogenic.
Tuberculosis can survive outside the human body,
but its mode of transmission is by droplet nuclei.
When infected individuals a cough, they release
droplet nuclei into the air, and these carry the
Tuberculosis organism. These droplet nuclei may
be breathed in by another person, but prolonged
exposure to the infected person is usually
necessary for infection to occur.
HIV and Viral Hepatitis are both viruses that are
not living cells themselves but can duplicate when
in a living "host" cell. Both of these organisms are
usually passed on by person-to-person contact,
and both need to be in the human body to survive.
Once outside the body, viruses do not survive.
