AIDS is a systemic disease caused by the human immunodeficiency virus, with no specific clinical manifestations. Patients with the infection show symptoms regardless of gender, and both men and women can show similar symptoms. The main manifestations are various infections, such as oral candidiasis, tuberculosis and cytomegalic infection. Depending on the period of HIV infection, different symptoms may appear: 1. Acute phase: Some patients may have fever, general malaise, sore throat, cough and other symptoms of upper respiratory tract infection. A few patients may experience nausea, vomiting, diarrhea, joint pain, headache, rash, meningoencephalitis, acute polyneuritis or enlarged lymph nodes in the neck, axilla and occipital area or enlarged liver and spleen. After the acute phase has passed, the symptoms will also disappear. The symptoms are similar to those of a cold and therefore may be overlooked; 2. Asymptomatic phase: There are usually no symptoms, or swollen lymph nodes throughout the body may occur. Most patients will enter this period directly after re-infection, but some patients may enter after the acute phase, and this period is mostly not accompanied by obvious symptoms except for positive HIV antibody; 3. AIDS phase: belongs to the HIV attack period, often without prominent symptoms, and may have unexplained longer-term irregular low-grade fever, persistent generalized lymph node enlargement, persistent diarrhea, rapid weight loss, susceptibility to dementia, lymphoma, epilepsy, and other symptoms. If a woman has recently had high-risk sexual behavior or close contact with a person with HIV and these symptoms are accompanied, she should seek medical attention for HIV testing to achieve early detection, diagnosis and treatment.
