Behaviour and 5 factors that contribute to the disease of hiv and aids
See the Related Questions below.
HIV (Human Immunodeficiency Virus) is the viral infection that causes AIDS (Acquired Immunodeficiency Syndrome). The progression from HIV to AIDS occurs when the immune system becomes severely compromised, making individuals more susceptible to various infections and diseases. Here are five factors that contribute to the transmission and spread of HIV/AIDS:
1. Sexual Contact: The primary mode of HIV transmission is through unprotected sexual intercourse with an infected person. This includes l, , or oral sex without the use of barriers like condoms or dental dams.
2. Sharing Needles and Syringes: HIV can be spread through the sharing of contaminated needles or syringes, particularly among people who inject drugs. This includes using needles for drug use, tattooing, or body piercing without proper sterilization.
3. Blood Transfusion and Organ Transplantation: Until the mid-1980s, HIV could also be transmitted through infected blood transfusions or organ transplants. However, with advancements in blood screening and organ transplant procedures, the risk of transmission through these routes has been significantly reduced.
4. Mother-to-Child Transmission: HIV can be transmitted from an infected mother to her child during pregnancy, childbirth, or breastfeeding. However, with appropriate medical interventions, such as antiretroviral therapy (ART) during pregnancy and delivery, the risk can be significantly minimized.
5. Occupational Exposure: Healthcare workers, laboratory personnel, and first responders can be exposed to HIV-infected blood or bodily fluids through accidental injuries, like needlestick injuries or contact with open wounds. However, the risk of transmission in healthcare settings is relatively low, thanks to strict protocols, universal precautions, and the use of personal protective equipment.
Understanding these factors is crucial for HIV prevention efforts and raising awareness about safe practices. It's important to promote HIV testing, access to condoms, harm reduction strategies, HIV education, and the availability of proper medical care for those infected with HIV/AIDS.
