大卫：感谢刘医生的回答！对于我们的下一个问题，您能解释一下新冠检测阳、检测阴性和具有COVID-19免疫力这几个术语吗？具体的说，如果我的新冠检测为阳性，但我随后被治愈，我是否会产生免疫力？之后，我还能给将新冠病毒传染给其他人吗？
刘医生：有一个诊断测试叫 PCR，它可以告诉你是否是新冠阳性。简单的说，如果您的检测结果为阳性，这意味着测试剂检测到您体内有新冠病毒。如果是阴性，则表示没有检测到新冠病毒。有时，PCR检测会出现假阴性，意味着虽然你的测试结果说你没有病毒，但事实上你有。这种情况可能发生在 15-20% 的测试中。
刘医生：关于免疫力，PCR 检测的结果并不能告知你是否曾经有过感染，也不能告知你对病毒的免疫力。但如果你过去有过新冠感染，现在痊愈了，我们希望你有免疫力，但这方面的研究还在进行

DAVID: Thank you for your answer to that question, Dr. Lio. Can you clarify the terms COVID positive, COVID negative, and COVID immune? Specifically, if I was COVID-positive but I am then cured, do I develop immunity? Can I still give COVID to other people?
DR. LIO: There’s a diagnostic test called PCR, which can tell you if you’re positive or not. Basically, if you test positive that means they detect the virus in you. If it’s negative they don’t detect it. Sometimes there are false negatives. So you might get a PCR test that says you don’t have the virus, but you do. This might happen in maybe 15-20% of the tests.
DR. LIO: With regard to immunity, the PCR test does not tell you whether you have had it in the past and whether you are immune from that. However, if you have had COVID in the past and now are better, we think/hope that you have immunity, but the research is still ongoing. However, if you compare it to other virus infections, such as other coronaviruses, we do know that people have some immunity.
