Which virus destroys the human immune system and can lead to AIDS?

HIV, or Human Immunodeficiency Virus, is the virus responsible for damaging the human immune system. It specifically targets and attacks CD4 T cells, which play a crucial role in the immune response. Over time, if untreated, HIV can progress to Acquired Immunodeficiency Syndrome (AIDS), a condition where the immune system becomes severely impaired, making the body susceptible to opportunistic infections and certain cancers.

The other viruses listed do not have the same impact on the immune system as HIV. Hepatitis B primarily affects the liver rather than the immune system as a whole. Influenza is a respiratory virus that can cause significant illness but does not target the immune system specifically in the way HIV does. Human Papillomavirus (HPV) is related to certain types of cancer but does not destroy the immune system like HIV. Therefore, HIV is the correct choice as it is the only virus listed that directly leads to AIDS through immune system degradation.
