In summary, HIV infects and compromises the immune system by targeting and destroying CD4+ T cells, which are important white blood cells responsible for coordinating the immune response against infections. While CD4+ T cells are the main target of HIV, the virus can also infect and damage other immune cells such as macrophages, dendritic cells, and B cells. HIV replicates by inserting its genetic material into the DNA of the infected CD4+ T cells using an enzyme called reverse transcriptase, allowing it to spread throughout the body. If left untreated, HIV can severely damage the immune system and lead to AIDS, making the body more vulnerable to infections and potentially resulting in death. However, HIV can be managed and treated with antiretro

1. How does HIV infect and compromise the immune system?

HIV infects and compromises the immune system by targeting and destroying CD4+ T cells, which are important white blood cells responsible for coordinating the immune response against infections. This leads to a decrease in the body's ability to fight off infections and diseases.

2. Can HIV directly attack other immune cells besides CD4+ T cells?

While CD4+ T cells are the main target of HIV, the virus can also infect and damage other immune cells such as macrophages, dendritic cells, and B cells. This further weakens the immune system and makes the body more susceptible to infections.

3. How does HIV replicate and spread throughout the body?

HIV replicates by inserting its genetic material into the DNA of the infected CD4+ T cells using an enzyme called reverse transcriptase. This allows the virus to make multiple copies of itself and spread to other cells through the bloodstream.

4. What are the long-term effects of HIV on the immune system?

If left untreated, HIV can severely damage the immune system over time, leading to a condition known as acquired immunodeficiency syndrome (AIDS). This makes the body more vulnerable to opportunistic infections and can eventually result in death.

5. How can HIV be managed and treated to prevent immune system compromise?

HIV can be managed and treated with antiretroviral therapy (ART), a combination of medications that can effectively suppress the virus and prevent it from replicating. This allows the immune system to recover and reduces the risk of developing AIDS and other complications.
