You can get AIDS even if you are clean. AIDS refers to Acquired Immunodeficiency Syndrome and is caused by infection with the Human Immunodeficiency Virus. The existence of the disease is likely to be caused when a crowd has sexual contact with a person suffering from AIDS. In addition, even if a person is clean, the disease can also be caused if he or she is accidentally pierced by an HIV-infected needle or if he or she is fed contaminated blood products. It is recommended that people with HIV go to the hospital as soon as possible, and under the guidance of the doctor, choose the appropriate medication to control the disease, which will help prolong life. In daily life, they should try not to use drugs intravenously or go to irregular places for medical operation, so as to effectively reduce the possibility of spreading the disease.
