Hospitalization requires an HIV test in most cases. AIDS is mainly transmitted through sexual intercourse, blood, and mother-to-child transmission, so hospitalization is required in most cases to check for four infections, including AIDS. In addition to surgeries and blood transfusions, HIV testing is required for puncture, gastroenteroscopy, bronchoscopy, hemodialysis and other invasive procedures, as well as for the safety of healthcare workers. If a patient’s disease is considered to be related to AIDS, an HIV test is also required to provide a full picture of the patient’s condition and better treatment. During the hospitalization period, patients should remember to submit their test results from the outpatient clinic, reflect their physical condition to the doctors and nurses in a timely manner, and bring their personal belongings with them before they are hospitalized.
