Characteristics of Acquired Immune Deficiency Syndrome (AIDS)
AIDS is a serious medical condition caused by the human immunodeficiency virus (HIV) and is characterised by the following:
Reduction in the number of helper T-cells:
- HIV attacks and kills the helper T-cells, which play a crucial role in the immune system by activating and directing other immune cells to fight infections.
- As a result, the number of helper T-cells in the body decreases, impairing the immune system's ability to combat infections.
Presence of killer T-cells:
- HIV also infects and activates the killer T-cells, which are responsible for destroying infected cells in the body.
- However, the activation and proliferation of killer T-cells is not enough to control HIV replication or prevent disease progression.
Other immune system dysfunctions:
- HIV also affects other components of the immune system, such as B-cells, natural killer cells, and macrophages, leading to immune dysfunction and susceptibility to infections and cancers.
Symptoms:
- The symptoms of AIDS vary depending on the stage of the disease, but can include fever, fatigue, weight loss, diarrhoea, skin rashes, and opportunistic infections.
Treatment:
- There is no cure for AIDS, but antiretroviral therapy (ART) can suppress HIV replication and restore immune function, leading to improved health outcomes and prolonged survival.
Prevention:
- Prevention strategies include safe sex practices, use of condoms, pre-exposure prophylaxis (PrEP), and HIV testing and treatment.
