In fact, the clinical manifestations of AIDS are extremely complex, and AIDS lacks characteristic clinical manifestations. Here is a brief introduction to the clinical manifestations of AIDS.
After a person is infected with HIV, the clinical manifestations range from no clinical symptoms to severe disease lesions, constituting a series of disease manifestations, including acute HIV infection, asymptomatic HIV infection and the AIDS stage. The time from HIV infection to the onset of signs and symptoms of AIDS is usually 6 months to 5 years, with some cases lasting up to 10 years, with an average of 29 months for adults and 12 months for children.
Acute HIV infection has symptoms of upper respiratory tract infection such as fever, malaise, sore throat, general malaise; individual headache, rash, meningitis or polyneuritis; swollen lymph nodes in the neck, axilla, and occiput resembling infectious mononucleosis; enlarged liver and spleen.
Asymptomatic HIV infection: Patients often do not have any signs and symptoms.
The clinical manifestations of patients with HIV infection are diverse, including immune deficiency of unknown origin; persistent irregular fever for more than 1 month; persistent generalized lymph node enlargement of unknown origin; chronic diarrhea more than 4-5 times/day, weight loss of more than 10% within 3 months; combined oral candidiasis, Pneumocystis carinii pneumonia, cytomegalovirus (CMV) infection, toxoplasmosis, cryptococcal meningitis, rapidly progressing active tuberculosis, and hepatosplenomegaly. Rapidly active tuberculosis, Kaposi’s sarcoma of the skin and mucous membranes, lymphoma, etc.; dementia may also develop in young and middle-aged patients.
Anyone should be aware that neither fever, swollen lymph nodes, nor diarrhea are unique to AIDS, and in most cases are caused by other common diseases. The time required from HIV infection to antibody formation is usually about 5 weeks, therefore, after having unclean sexual intercourse or blood transfusion, most people can have their blood drawn to test whether they have been infected with AIDS after about 5 weeks.
