In Spain we have limited access to the control PCR test (even in healthcare facilities) and we are seeing covid + patients with persistent cough after three weeks of PCR +.
How long do you estimate that patients are contagious after a positive PCR?
When could we consider that although they continue coughing, they are no longer contagious, in order to end the isolation?
If you are a health worker and you persist with a cough, do you think your return to work is safe? / 问题:在西班牙，PCR检测的资源非常有限(甚至对于医护人员也是如 此)。有患者在PCR检测呈阳性三周后，还是有持续咳嗽的症 状。 一般估计患者在PCR检测呈阳性后他的传染性会持续多久? 什么时候可以判定已经没有传染性，从而结束隔离，即便患 者还有咳嗽症状? 如果是一位医护人员，而且有 持续咳嗽症状，您认为他返回 工作岗位安全么?
