COVID-19 patients (n = 114) were included (55 patients with pneumonia (group P) and 59 without pneumonia (group NP). Patients in group P were older (69 (±17) years vs 46 (±16); p < 0.001) with a male predominance (58.2% vs 27.1%; p < 0.001). The symptoms which were statistically more frequents in patients with pneumonia were fever ≥ 38 °C (93% vs 70%; p = 0.002) and dyspnea (73% vs 22%; p < 0.001). Symptoms such as facial headache (42% vs 15%; p = 0.001), sore throat (39% vs 16%; p = 0.007), dysgeusia (61% vs 33%; p = 0.003), anosmia (63% vs 31%; p = 0.001) were statistically more frequents in patients without pneumonia.

纳入COVID-19患者（n = 114）（55例肺炎（P组）和59例非肺炎（NP组）。P组患者年龄较大（69（±17）岁，而46（±16）岁；p <0.001），男性占多数（58.2％vs 27.1％；p <0.001）。据统计，肺炎患者更常见的症状是发烧≥38 °C（93％vs 70％；p = 0.002）和呼吸困难（ 73％vs 22％; p <0.001）。面部头痛（42％vs 15％; p = 0.001），喉咙痛（39％vs 16％; p = 0.007），消化不良（61％vs 33％; p = 0.003），无肺炎患者的失眠频率（63％vs 31％; p = 0.001）在统计学上更高。
