The statement “6 signs of AIDS in men” is unscientific. Early stage of AIDS and asymptomatic infected patients do not have obvious clinical symptoms, or only have mild non-specific symptoms. By the end of the AIDS period, some patients may have difficulty breathing, sudden weight loss, persistent fever, skin lesions, swollen lymph nodes, neurodegenerative lesions and other symptoms. 1. Difficulty in breathing: patients have difficulty in breathing, coughing and other symptoms, and Pneumocystis carinii can be detected in sputum culture test. 2. Sudden lethargy: If the patient has a history of drug abuse or drug tourism, and then suddenly develops anorexia, vomiting, nausea, etc., and the use of anti-infective drugs is ineffective, and exclude digestive diseases, then consider the possibility of HIV infection. 3. Persistent low-grade fever: If the patient has a history of drug abuse or drug addiction, and has a persistent fever and weakness for a month, and excludes other causes of fever, then AIDS should be suspected. 4. Skin damage: During the incubation period of AIDS patients, the virus will gradually attack the skin, causing local skin rashes, urticaria, skin breakage symptoms, and combined with the patient’s history of gambling and sexual contact, it should be considered to be caused by HIV infection. 5. Enlarged lymph nodes: patients may inadvertently find enlarged lymph nodes at the back of the neck, submandibular, under the chin, and there is no infection or other discomforts, and no other causes can be identified, then HIV infection should be considered. 6. Neurodegenerative disease: patients may have muscle pain, mental retardation, slow reaction, mental abnormality and other symptoms. It is worth noting that no symptom can be used as a basis for diagnosing AIDS, and it is necessary to go to the hospital for examination. If AIDS infection is suspected, you should seek immediate medical examination and prompt treatment.
