49470 多数感染新冠肺炎病毒的患者为轻症并可痊愈。 Most people infected with COVID-19 virus have mild disease and recover.
49471 约80%的实验室确诊病例为轻症和普通型，包括无肺炎或肺炎患者，13.8%的患者为重症，存在呼吸困难、呼吸频率>=30次/分钟、血氧饱和度593%、动脉血氧分压/吸入氧浓度比<300和/或24-48小时内肺部浸润>50%, 6.1%的患者为危重型（呼吸衰竭、脓毒性休克和/或多器官功能障碍/衰竭）。 Approximately 80% of laboratory confirmed patients have had mild to moderate disease, which includes non-pneumonia and pneumonia cases, 13.8% have severe disease (dyspnea, respiratory frequency >30/minute, blood oxygen saturation <93%, PaO2/FiO2 ratio <300, and/or lung infiltrates >50% of the lung field within 24-48 hours) and 6.1% are critical (respiratory failure, septic shock, and/or multiple organ dysfunction/failure).
49472 巳有无症状感染的报告，但多数在报告时无症状的病例随后会出现症状。 Asymptomatic infection has been reported, but the majority of the relatively rare cases who are asymptomatic on the date of identification/report went on to develop disease.
49473 真正的无症状感染者的比例尚不明确，但相对较罕见，也不是传播的主要驱动因素。 The proportion of truly asymptomatic infections is unclear but appears to be relatively rare and does not appear to be a major driver of transmission.
49474 重症和死亡高危人群为年龄60岁以上，以及患有高血压、糖尿病、心血管疾病、慢性呼吸道疾病和癌症等基础性疾病者。 Individuals at highest risk for severe disease and death include people aged over 60 years and those with underlying conditions such as hypertension, diabetes, cardiovascular disease, chronic respiratory disease and cancer.
49475 儿童病例似乎很少且病情较轻，19岁以下病例约占总报告病例的2.4%。 Disease in children appears to be relatively rare and mild with approximately 2.4% of the total reported cases reported amongst individuals aged under 19 years.
49476 极少数19岁以下病例发展为重症(2.5%)或危重症（0.2%)。 A very small proportion of those aged under 19 years have developed severe (2.5%) or critical disease (0.2%).
49477 截至2月20日，55924例实验室确诊病例中有2114例死亡（粗病死率[CFR]为3.8%) As of 20 February, 2114 of the 55,924 laboratory confirmed cases have died (crude fatality ratio [CFR2] 3.8%)
49478 (注：其中包含部分由临床诊断病例转成的确诊病例）。 (note: at least some of whom were identified using a case definition that included pulmonary disease).
49479 粗病死率因地区和传播强度而异（武汉5.8%，中国其他地区0.7%)。 The overall CFR varies by location and intensity of transmission (i.e. 5.8% in Wuhan vs. 0.7% in other areas in China).
