The latest types of viruses infecting humans today are the enzootic and epizootic viruses; these viruses come from the transmission of animals to humans. Another virus, Human immunodeficiency virus (HIV), …show more content…
Studies show however that the recombination of the genome poses more harmful effects; the structure and proteins of the virus begin to break causing the virus’s ability to infect the cell to function at a less optimum level and replicate at a slower rate. Recombination is an important aspect in host switching since it allows the virus to better adapt in a different environment. The adaptation for a host-switching virus can take variable amounts of time; some adapt faster than others. A reason seen for this is the binding site on the host cell; those receptors that are more hospitable will allow the virus to infect the cell faster and will allow the virus to remain in the cells for a longer period of
