HIV/AIDS is caused by the HIV virus which attacks the immune system. It is transmitted through bodily fluids and can be diagnosed through blood tests. Early symptoms include fever, weight loss, and fatigue. While there is no cure for AIDS, treatment with antiretroviral drugs can control the virus and prevent symptoms. India has a growing problem with HIV/AIDS, with over 1.7 lakh people estimated to be living with HIV in Uttar Pradesh alone.
