Infection Methods
Exogenic
▸
Majority of viral infections

\usepackage in a document
Endogenic
▸
5 – 8% of our own genetic pool (retro-viruses)
▸
\RequirePackage in a class
▸
T

XLive 2009: 95% classes have 4 (av.) endogenic
infections
Endosymbiosis

e.g. mitochondria ⇐ former prokaryotes

▸
\let\@ldfoo\foo\def\foo{...\@ldfoo ...}
\renewcommand etc.
Satellites
▸
Delta virus (HDV) over HBV
▸
DoX, Graphicx etc.
Host-dependent
▸
Rely on the host instead of another virus
▸
e.g. Beamer themes
Cheaters
▸
Competition instead of cooperation
▸
e.g. Umbravirus steals coat protein from Luteovirus
▸

There are too many problems with varioref.
Nobody has time to sort them out. Therefore
this package is now unsupported.

Adaptive Immunity
▸
Acquisition of defenses against a pathogen

Immunological memory:
history of previously encountered infections

Active immunological memory: long-term
●
Naturally acquired: mumps, measles etc.
