Common symptoms during acute infection of HIV include fever, night sweats, sore throat, diarrhea, joint pain, swollen lymph nodes, rash and other symptoms, which usually last for 1~3 weeks and then resolve on their own. Rash usually manifests as red or reddish-brown papules and macules, so red dots on the neck of AIDS patients may be the manifestation of rash during this period. During the AIDS period, due to the impaired immune system, patients are also prone to combining other diseases, including various infectious and non-infectious skin diseases, such as eczema, dermatitis, psoriasis, etc., which may also be manifested as a symptom of red dots on the neck.
