What happens to the immune system of a person with hiv, and how may that infection develop into aids?

describe how the nervous system different parts of your body communicate with one another the moment you begin to pet a dog.

At the time of infection with HIV, the higher the number of CD4+ cells that become damaged, the weaker the immune system becomes and the less able a person is to fight off infection and disease. Eventually, this results in the development of AIDS.

When touching things, like a dog, it will send your brain a signal of what the dog feels like and the brain send it back to your hand.

Hope this helps!
