Infected persons are usually patients of certain infectious diseases, and are subject to different treatments according to the virulence of the infectious diseases, and sometimes even quarantine measures are taken. 1. Physical isolation: In order to prevent repeated infections and cross-infections among infected patients, physical isolation is usually carried out for those infected with some virulent infectious diseases, so as to prevent the spread and propagation of the disease and to control the source of infection. 2. Symptomatic treatment: For patients with severe symptoms after infection, we usually adopt symptomatic treatment, which aims at eliminating patients’ symptoms, maintaining patients’ vital signs, and ensuring that patients’ vital signs do not undergo significant changes to the extent of endangering their lives. 3. Etiological treatment: For patients who have identified the cause of the disease, treatment is aimed at the cause of the infection, with the aim of eliminating the infection and promoting the health of the patient. If you are unfortunate enough to suffer from an infection, you should go to the hospital in time to find out the cause of the disease, and carry out the treatment under the guidance of the doctor, so as not to be negligent, so as not to cause a delay in the disease.
