Detailed explanation-1: -HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome). There is currently no effective cure. Once people get HIV, they have it for life. But with proper medical care, HIV can be controlled.

Detailed explanation-2: -HIV (human immunodeficiency virus) is a virus that attacks cells that help the body fight infection, making a person more vulnerable to other infections and diseases.

Detailed explanation-3: -While HIV is a virus that may cause an infection, AIDS (which is short for acquired immunodeficiency syndrome) is a condition. Contracting HIV can lead to the development of AIDS. AIDS, or stage 3 HIV, develops when HIV has caused serious damage to the immune system.

Detailed explanation-4: -There are two types of HIV, HIV-1 and HIV-2, as well as several related viruses that infect certain monkeys or great apes. HIV-1 can be found throughout the world, but HIV-2 is almost exclusively limited to West Africa. HIV-1 is transmitted more easily than HIV-2, and HIV-1 infection progresses more rapidly to AIDS.

Detailed explanation-5: -Deep, Open-Mouth Kissing Very rarely, transmission has occurred if both partners have sores or bleeding gums. You can’t transmit HIV through closed-mouth or “social” kissing with someone who has HIV. You can’t transmit HIV through saliva.
