Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system, which can lead to acquired immunodeficiency syndrome (AIDS) if left untreated. HIV is primarily spread through unprotected sexual contact, sharing of needles or syringes, and from mother to child during childbirth, pregnancy or breastfeeding.
The virus is transmitted through bodily fluids, including blood, semen, vaginal fluids, breast milk, and rectal secretions. HIV can be transmitted when these fluids come into contact with mucous membranes, such as those found in the vagina, anus, mouth, and eyes, or through breaks in the skin, such as cuts or sores.

The most common mode of transmission is through sexual contact, which accounts for the majority of HIV cases globally. Unprotected vaginal, anal, or oral sex with an infected partner can lead to transmission of the virus. Anal sex carries a higher risk of transmission than vaginal sex because the lining of the rectum is more fragile and prone to tearing, which can create a pathway for the virus to enter the bloodstream.
Sharing needles or syringes with an infected person is another common way that HIV is spread. This can happen when people inject drugs, steroids, or hormones, and share needles or syringes. The virus can also be transmitted when needles or syringes are reused or when injection equipment is shared, such as cookers, cotton, and water.
Mother-to-child transmission is another mode of transmission. An infected mother can transmit the virus to her child during pregnancy, childbirth, or breastfeeding. Without intervention, the risk of transmission is around 15-45%. However, with appropriate medical care, the risk of mother-to-child transmission can be significantly reduced to less than 2%.
HIV can also be transmitted through blood transfusions or organ transplants from an infected donor. However, this mode of transmission is extremely rare in countries with well-established blood screening and donation systems.
In addition, there are a few other less common ways that HIV can be transmitted. These include occupational exposure, such as needle stick injuries or exposure to infected blood, and oral sex, although the risk of transmission through oral sex is lower than through vaginal or anal sex.
It is important to note that HIV is not spread through casual contact, such as hugging, kissing, or sharing food or drinks. The virus is also not spread through mosquito bites or other insect bites.
Preventing the transmission of HIV involves adopting safe behaviors, such as using condoms consistently and correctly during sexual activity, not sharing needles or injection equipment, and getting tested for HIV regularly. In addition, HIV-positive individuals can reduce the risk of transmission by adhering to antiretroviral therapy (ART) and maintaining an undetectable viral load, which significantly reduces the risk of transmitting the virus to others.
In conclusion, HIV is primarily spread through unprotected sexual contact, sharing of needles or syringes, and from mother to child during childbirth, pregnancy, or breastfeeding. Preventing the transmission of HIV involves adopting safe behaviors and getting tested for HIV regularly. With appropriate medical care, HIV-positive individuals can lead long and healthy lives while also reducing the risk of transmission to others.
