Virus infected patients develop neutralizing antibodies. These are blood proteins, that glob onto the virus and would allow patients to defend themselves - if they were facing only one target. But, the virus disguises itself enough to get away from the antibodies. The virus eventually wears down the immune system into exhaustion.

How do viruses stay hidden?
Viruses can stay hidden by mutating frequently to avoid detection by the immune system. Some viruses can also enter a dormant state within host cells, making them hard to detect and target for treatment. Additionally, viruses can evade the immune response by altering their surface proteins to avoid recognition by antibodies.
How can protozoa avoid being killed by the host immune system?
Protozoa can evade the host immune system by changing their surface antigens to avoid detection and destruction. Some protozoa can also reside within host cells to escape immune detection, or they can suppress the host's immune response by secreting immunomodulatory molecules. Additionally, some protozoa can cause chronic infections by altering their replication rate to avoid being completely eradicated by the immune system.
Why haven't viruses wiped out the human population?
Viruses haven't wiped out the human population due to many people being able to take enough precautions to avoid it all together. Other people are immune to certain viruses that might prove fatal to others. Also, vaccines have been created to reduce deaths among illneses such a the cold virus, flu, fever, etc. So: -taking precautions to avoid the virus -Being immune -Vaccines are just a few answers to why the human population hasn't been wiped out by viruses. Oh, and because we reproduce rather frequently.
Why is it hard to get rid of viruses in your body?
Viruses can be challenging to eliminate because they can mutate rapidly, making it difficult for the immune system to target them effectively. Additionally, viruses can evade detection by hiding inside cells or evolving mechanisms to avoid destruction. Lastly, some viruses have the ability to establish latent infections, where they remain in the body in a dormant state and can reactivate later.
Why leishmania lives within macrophages?
Leishmania lives within macrophages because it has adapted to evade the host immune system by exploiting the intracellular environment of these immune cells. By residing inside macrophages, Leishmania can avoid detection and destruction by the host's immune response, allowing it to establish a chronic infection.
