To date there is no standard treatment for SARS. To raise the survival rate doctors may give antiviral agents such as ribavirin and interferon during the initial stage of infection thus preventing the initial massive replication of the virus in the body. During the middle stage of the disease, to prevent the patient's immune system from becoming over-stimulated, it is necessary to administer steroids and immunoglobulin to weaken and adjust the immune reaction.
SARS 迄今沒有標準療法，為了提高存活率，一般來說，在感染初期，醫生可能施打干擾素或 ribavirin 等抗病毒藥物，先阻止病毒在體內大肆複製；感染中期，為了避免患者的免疫系統被過度激化，又必須使用類固醇及免疫球蛋白，以降低並調節免疫力。
