Introduction:
Disease caused by viral infections can be devastating on a local and worldwide basis. Treatment of such infections, although not impossible, is difficult, and many viral infections in a individual have to be left to run their course (although certain symptoms can be treated). The best strategies employed for viral infections are, therefore, those of prevention. The preventative measures can be classified as two main categories, epidemiological control and vaccination, however, both methods are usually used in conjunction with one another.

Epidemiology is the spread of viruses from one organism to another. As obligate intracellular parasites, viruses have had to develop a number of effective routes for transfer between their hosts.
