Question: Highlight three major ways by which hiv/aids can be contacted?

HIV/AIDS can be transmitted through several routes. Here are three major ways by which HIV/AIDS can be contracted:

1. Unprotected Sexual Contact: The most common mode of HIV transmission is through unprotected sexual contact with an infected person. This includes vaginal, anal, and oral sex without the use of barrier methods such as condoms or dental dams. Both heterosexual and homosexual sexual activities can lead to HIV transmission if one of the partners is infected.

2. Sharing Contaminated Needles and Syringes: HIV can be contracted by sharing contaminated needles, syringes, or other drug paraphernalia with an infected person. This mode of transmission commonly occurs among people who inject drugs. Sharing needles can introduce the virus directly into the bloodstream, facilitating the spread of HIV.

3. Mother-to-Child Transmission: HIV can be transmitted from an HIV-positive mother to her child during pregnancy, childbirth, or breastfeeding. Without proper interventions, the risk of transmission from mother to child can be as high as 15-45%. However, with effective antiretroviral therapy (ART) and other preventive measures, the risk can be significantly reduced to less than 1%.

It's important to note that HIV is not transmitted through casual contact, such as hugging, kissing, sharing utensils, or mosquito bites. The virus is primarily spread through specific bodily fluids, including blood, semen, vaginal fluids, and breast milk. Understanding the modes of transmission and practicing preventive measures, such as consistent condom use, harm reduction strategies, and access to HIV testing and treatment, can greatly reduce the risk of contracting HIV/AIDS.
