HIV

Health Care Term

HIV (Human Immunodeficiency Virus) is a retrovirus that attacks the immune system, specifically the CD4 cells that help the body fight infections and diseases. HIV weakens the immune system over time, making individuals infected with the virus more vulnerable to other infections, diseases, and cancers. If left untreated, HIV can progress to AIDS (Acquired Immunodeficiency Syndrome), which is the most advanced stage of HIV infection.

HIV is primarily transmitted through unprotected sexual contact, sharing contaminated needles, prenatal transmission from a mother to her child, and blood transfusions. Prevention methods such as practicing safe sex, using clean needles, pre-exposure prophylaxis (PrEP), and post-exposure prophylaxis (PEP) can help reduce the risk of contracting HIV.

The Health Care Industry uses HIV screening tests to diagnose and monitor the progression of HIV infection. Antiretroviral therapy (ART) is a combination of medications that can slow down the progression of HIV infection by blocking its replication and reducing the amount of virus in the body, hence increasing the CD4 cell count. ART can improve the quality of life of people living with HIV and help them achieve an undetectable viral load, which prevents further transmission of the virus.

Additionally, healthcare providers offer pre- and post-HIV exposure prophylaxis as a preventive measure for individuals who may have been exposed to HIV. They also provide counseling services and support groups for people living with HIV/AIDS to help manage their physical and emotional needs. Investing in research and development of HIV vaccines and cure is also another area in which the health care industry is committed to developing in the fight against HIV/AIDS.
