The first human disease associated with a filterable agent was Yellow fever
From clinical point of view, viruses are considered to be alive as they cause infection and disease (just as pathogenic bacteria, fungi, and protozoa do)
The trully distinctive features of viruses are now known to relate to their:
Viruses have few or no enzymes of their own for metabolism; for example, they lack enzymes for protein synthesis and ATP generation
For some bacteriophages, the receptor site is part of the cell wall of the host
The percentage of NA in relation to protein is about 1% for the influenza virus and about 50% for certain bacteriophage
Spikes are a reliable characteristic of some virus, can be used for identification
When the host has been infected by a virus, the host immune system is stimulated to produce antibodies
The suffix -virinaedenotes a subfamily. Viral genera aredesignated by the suffix -virus
