AIDS bumps are usually red or reddish-brown spots or papules that appear on the neck, face and trunk, and are usually not accompanied by itching. The majority of patients develop the rash within 2 to 4 weeks after infection with the virus. It is usually a reddish or reddish-brown macular or papular rash, often appearing on the neck, face and trunk, and can also appear all over the body, and is usually not accompanied by itching, but a few patients may have itching, and will recover on its own within 1 to 3 weeks. The rash in the acute phase of AIDS is not specific, and may be accompanied by other symptoms such as fever, sore throat, swollen lymph nodes, etc. These symptoms are not the basis for a definitive diagnosis of AIDS, and it is necessary to go to a regular hospital for HIV antibody tests to confirm the diagnosis of HIV infection.
