HIV - Viral Diseases - GCSE Biology

🦊 In this GCSE Biology video, we provide an overview of HIV (Human Immunodeficiency Virus), explaining that it attacks and infects white blood cells, thereby damaging the immune system. Initially, HIV infection may cause flu-like symptoms, but infected individuals can remain symptom-free for many years. The video emphasizes the importance of good healthcare and antiretroviral drugs in prolonging the time between infection and the onset of AIDS (Acquired Immunodeficiency Syndrome), the late stage of HIV. Additionally, the video discusses HIV transmission, noting that it is spread through sexual contact or the exchange of body fluids, such as blood, and that avoiding high-risk behaviours like unprotected sex or sharing needles can reduce the risk of contracting HIV. For exams, it's important to know HIV's initial symptoms, its management with antiretroviral drugs, and its transmission routes.
