The Original Taxonomy of Viruses

The taxonomy of viruses is well known to all and is still in progress, as science is. But do you know what the original taxonomy was? Quite simply, it consisted of infectivity, filterability and their requirement for human hosts.

Infectivity is how well the virus infects a host, which quite determines it's strength.

Filterability represents how well it can be filtered through the chamberland filter (refer to previous post on the birth of virology).

Finally, their requirement for hosts, such as which kind, perhaps humans. This determines their flexibility.

Through these, viruses were first classified. Of course, like I mentioned earlier, the road of change is never ending. Who knows, maybe you may be next to change this taxonomy.
