Clinically, most of the cases were stable, only 10 showed severe conditions. All recovered after standard treatment. The initial misdiagnosis rate was 32.40% (58/179), which was higher in township health centers (61.5%, 8/13) and private clinics (97.1%, 34/35). The median intervals from onset to primary diagnosis, primary diagnosis to confirmation, onset to confirmation, and confirmation to medication were 1, 1, 3 and 0 days, respectively.
