What virus is known to cause AIDS?

HIV virus
Flu virus
Herpes virus
Hepatitis B virus

The correct answer is: HIV virus

The HIV virus is the causative agent of AIDS (Acquired Immunodeficiency Syndrome). HIV stands for Human Immunodeficiency Virus, which specifically targets and gradually destroys the immune system's CD4 cells, leading to the progressive condition known as AIDS. When the immune system is severely compromised due to the depletion of these critical cells, the body becomes vulnerable to opportunistic infections and certain cancers, marking the shift from HIV infection to AIDS. The other viruses listed do not cause AIDS. The flu virus is responsible for influenza, a respiratory illness, while the herpes virus can lead to conditions like oral and genital herpes but does not affect the immune system in the same way. Hepatitis B virus primarily affects the liver and can lead to liver disease but is not associated with AIDS. Understanding the specific roles and impacts of these viruses on health is crucial in the field of cosmetology and beyond, particularly when it comes to infection control practices.
