What are the mist cimmon ways that HIV is passed from one person to another?

HIV is primarily transmitted through certain bodily fluids, including blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk. The most common ways that HIV is passed from one person to another include:

1. Unprotected Sexual Contact: HIV can be passed through unprotected sex, including vaginal, anal, or oral sex, when one partner is infected with the virus and the other is not.

2. Sharing Needles and Syringes: Sharing needles, syringes, or other drug paraphernalia used for injecting drugs can transmit HIV if one person is infected with the virus.

3. Blood Transfusions and Organ Transplants: Before widespread screening of blood and organs, HIV could be transmitted through blood transfusions or organ transplants from an infected donor to a recipient. However, with modern screening practices, this risk has been significantly reduced in many countries.

4. Mother-to-Child Transmission: HIV can be passed from an infected mother to her child during pregnancy, childbirth, or breastfeeding. Without proper medical interventions and treatment, the risk of transmission is substantial. However, with appropriate medical care and interventions, this risk can be reduced significantly.

5. Accidental Needlestick Injuries: Healthcare workers or others who may come into contact with contaminated needles or sharp objects can potentially be exposed to HIV through accidental needlestick injuries or other sharps-related injuries.

It's important to note that HIV is not spread through casual contact such as shaking hands, sharing utensils, or touching someone who is infected. The virus requires specific routes of transmission involving the exchange of bodily fluids to be transmitted from an infected person to an uninfected person.
