AIDS is known as Acquired Immunodeficiency Syndrome, a serious immune deficiency caused by HIV (Human Immunodeficiency Virus) infection that destroys the immune system. From the time of HIV infection to the development of AIDS, it can be roughly divided into three stages: acute HIV infection, asymptomatic HIV infection and AIDS. Each stage may have symptoms such as enlarged lymph nodes throughout the body, so AIDS is usually characterized by swollen lymph nodes. However, simply from the symptom of swollen lymph nodes can not confirm the diagnosis of AIDS, swollen lymph nodes may also be caused by other diseases, you need to go to the hospital in time for further examination, to clarify the cause of the disease, and active treatment.
