RT-PCRs to detect SARS-CoV-2 RNA is key to manage the COVID-19 pandemic. We analyzed SARS-CoV-2 viral loads from 22′323 RT-PCR results according to samples types, gender, age, and health units. Viral load did not show any difference across age and appears to be a poor predictor of disease outcome. SARS-CoV-2 viral load showed similar high viral loads than the one observed for RSV and influenza B. The importance of viral load to predict contagiousness and to assess disease progression is discussed.

患者间SARS-CoV-2的病毒载量，并与其他呼吸道病毒进行比较。

RT-PCR检测SARS-CoV-2 RNA是管理COVID-19大流行的关键。我们根据样本类型，性别，年龄和健康单位，从22'323 RT-PCR结果中分析了SARS-CoV-2病毒载量。病毒载量在各个年龄段均未显示任何差异，并且似乎不能很好地预测疾病的预后。SARS-CoV-2病毒载量显示出与RSV和B型流感病毒相似的高病毒载量。讨论了病毒载量对于预测传染性和评估疾病进展的重要性。
