ELI5 HIV, AIDS and how are they related to each other?
gpt
HIV is a bug that causes AIDS. AIDS is a sickness where the bits of your blood that hunt down other sicknesses stop working. Those bits are your T cells. HIV can sneak into T-cells and take them over, so instead of hunting down sickness, they make more HIV. When there is enough HIV, then many sicknesses can attack you all at once, and that is what kills you.
