Objective To observe the level of serum IFN-2? in patients with severe acute respiratory syndrome(SARS). Methods The level of serum IFN-2? in 66 patients with SARS were measured by RIA, and healthy subjects served as control. Results The results showed that level of serum IFN-2? in patients with SARS in active period were significantly higher than that in control, and level of serum IFN-2? in severe type of patients with SARS either rose or fell. Conclusions The change of serum IFN-2? level indicated that cellular immunity participated in immunoreaction to SARS virus. The change of IFN-2? level in severe type of patients with SARS reflected the difference of immunoreaction in the patients.
