Differentiate between persistent and latent animal virus infections.

Persistent animal virus infection:

Persistent infections are those infection which are present continuously everytime or persistently present in animals and can be detected on their symptoms of infection or by diagnosis at the lab.

Latent animal virus infection:

Latent infections are those in which viruses are not active although they are present in the host but does not produce disease and whenever they found favorable environment they induced the disease in the host. Before this they will remain in latent phase means just present in the body but not produces the disease.

The difference between both infections is that viral infections where the virus is latent, this virus once infected is protected in the nerves of the animal organism, as for example in humans the herpes family viruses (HSV1) are housed in ganglionic terminals such as the trigeminal ganglion or the V cranial nerve, so that in a situation of immunodepression, reinfect the individual again, causing him to be unable to remove the virus from his body.

On the other hand, persistent infections diseases are the threats that persist because the microorganism cannot be eliminated, either because it is very complex, or the cure does not exist, or the correct treatment is not carried out. Furthermore, it is necessary to consider that some microorganisms mutate becoming resistant to these drugs and thus persist longer in the body until they are eliminated.

Explanation:

In short, latency refers to the fact that the individual lives with the virus for life, and persistence is that it is possible to eliminate it over a long period of time since the infectious microorganism is considered very difficult.
