Question

How can HIV/AIDS be transmitted from one person to another without having any form of sexual contact, and why?

Answer 1

HIV is not spread easily. Only certain body fluids from a person who has HIV can transmit HIV:

BloodSemen

Pre-seminal fluid

Rectal fluids

Vaginal fluids

Breast milk

These body fluids must come into contact with a mucous membrane or damaged tissue or be directly injected into your bloodstream (by a needle or syringe) for transmission to occur. 

Answer 2

Blood exchanges, notably through a syringe (sharing injecting equipment when injecting drugs, accidental bite from a health professional, blood transfusion before 1985)
Transmission from mother to child during pregnancy or breastfeeding.

There are only four liquid contaminants:

     -The blood,
    - The sperm and the fluid that occurs before ejaculation (pre-seminal fluid)
     -The Vaginal secretions
    - Breast milk.
