@Leighincognito @TrumpUndead @jonathanchait Don't rely on one study. May have been false positives, may have been tiny viral loads, or remnants from old already cleared infections. There is at least one recent study with cultured virus that finds no particular correlation between any symptom and infectiousness.
@Leighincognito @TrumpUndead @jonathanchait 不要依赖一项研究。可能是误报，可能是微小的病毒载量，或者是旧的已清除感染的残留物。最近至少有一项关于培养病毒的研究发现任何症状和传染性之间没有特别的相关性。
