Answer:
A person who receives a gene for sickle cell disease from one parent and a normal gene from the other has a condition called "sickle cell trait." Sickle cell trait produces no symptoms or problems for most people. Sickle cell disease can neither be contracted nor passed on to another person.
Answer:
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.
