Doss [256]
No this virus does not follow the Central Dogma of Biology. The Central Dogma refers to the process involved in cellular replication starting from the replication of DNA, followed by transcription of DNA to RNA, and finally translation of RNA to proteins.

Viruses are special because they hijack cells and use the cell's own mechanisms in order for it replicate. Retroviruses are even more special because they go against the unidirectional flow of the Central Dogma. This is done with the use of their <em>reverse transcriptase.</em>

This implies, epidemiologists focus on diseases outbreaks rather than on inherited diseases. Moreover, epidemiology plays an important role in preventive health as well as actions to control epidemics.
