Detailed explanation-1: -If the infection is not treated, it becomes chronic HIV infection. Often, there are no symptoms during this stage. If it is not treated, eventually the virus will weaken your body’s immune system. Then the infection will progress to AIDS.

Detailed explanation-2: -Asymptomatic HIV infection is the second stage of HIV/AIDS. During this stage, there are no symptoms of HIV infection. This stage is also called chronic HIV infection or clinical latency. During this stage, the virus keeps multiplying in the body and the immune system slowly weakens, but the person has no symptoms.

Detailed explanation-3: -Untreated, HIV typically turns into AIDS in about 8 to 10 years. When AIDS occurs, your immune system has been severely damaged. You’ll be more likely to develop diseases that wouldn’t usually cause illness in a person with a healthy immune system. These are called opportunistic infections or opportunistic cancers.

Detailed explanation-4: -A person with HIV can pass the virus on to others even if they do not have any symptoms. People with HIV can pass the virus on more easily in the weeks following infection. HIV treatment significantly reduces the risk of someone with HIV passing it on.

Detailed explanation-5: -HIV finds the white blood cells, called CD4 cells. HIV gets inside the CD4 cell and makes copies of itself. Then, HIV kills the CD4 cell and the new HIV copies find other CD4 cells to get inside and start the cycle again. HIV kills immune system cells that help the body fight infections and diseases.
