The six elements necessary for infection are a causative
organism, a reservoir of available organisms, a portal or mode of
exit from the reservoir, a mode of transmission from reservoir to
host, a susceptible host, and a
a) mode of entry to host.
The six elements necessary for infection are a causative organism, a

b) mode of exit from the host.
A mode of entry to the host, not a mode of exit from the host, is
necessary for infection.
c) virulent host.
