Methods Through the epidemiological analysis, collecting throat swab specimens and using RT-PCR test for the aetiology. Results 50 suspected cases were detected, 28 cases for males, 22 cases females. The ratio of males to females was 1.27 ： 1. Fever, sore throat, cough, headache, throat congestion were the main symptoms.
