摘要: Combined pharyngeal and nasal swab specimens were collected from 100 subjects who presented with a flu-like illness (fever >37.8 degrees C plus 2 of 4 symptoms: cough, myalgia, sore throat, headache) or =38.2 as well 3 the symptoms in clinical case definition. Stepwise logistic regression showed that cough (odds ratio [OR], 6.7; 95% confidence interval [CI], 1.4-34.1; P=.02) fever (OR, 3.1; CI, 1.4-8.0; P=.01) only factors significantly associated positive PCR test for influenza. The predictive value, negative sensitivity, specificity definition including (temperature >38 C) diagnosis influenza infection during this flu season 86.8%, 39.3%, 77.6%, 55.0%, respectively.
