What are symptoms of aids, if it is a subtle or mild case?

Often no symptoms. The symptoms of HIV infection in a subtle or mild case is usually nothing. This is why many people don't find out that they have HIV until after many years. However, as the immune system gets worse over time, the person may develop symptoms, like fevers, night sweats, weight loss, or enlarged lymph nodes. Untreated HIV infection can lead to aids, which is associated with a poor immune system.
