Not 90% of patients have symptoms in the early stages of AIDS. There are four main stages of AIDS: acute infection, asymptomatic infection, pre-AIDS and AIDS. The initial phase usually refers to the acute infection period, which is characterized by non-specific symptoms, i.e., 1-6 weeks after the patient is infected with AIDS. Most infected patients may have acute symptoms, which usually disappear within one month. If symptoms are present, they usually include malaise, fever, nausea, diarrhea, decreased appetite, and non-exudative pharyngitis. A smaller number of patients may also have hepatosplenomegaly, oral ulcers, encephalitis, peripheral neuritis, acute polyneuritis, and swollen lymph nodes in various parts of the body such as the neck and armpits. However, it does not necessarily mean that the patient is suffering from AIDS if the above symptoms appear. It is recommended to go to the hospital in time for relevant tests, such as HIV antibody test, HIV-RNA test, P24 antigen test, etc. If it is clear that the patient is in the early stage of AIDS, he/she should actively carry out antiviral chemotherapy and treatment drugs under the guidance of a professional doctor, and pay attention to rest and maintain emotional stability to help him/her recover from the disease.
