The mediating effect value of eHealth literacy and Qi stagnation constitution between tension and anxiety was 0.08 and 0.04 respectively,accounting for 16.33% and 8.16% of the total effect. Conclusions The anxiety of nurses in the infectious disease department of a hospital is obvious,which is closely related to perceived stress,eHealth literacy,Qi stagnation constitution and other factors.
