That stage is what we call the clinical latency period. That is when it appears to be clinically dormant. But from studying it carefully, we know it is not completely dormant. The virus is still replicating, except that the level is very low.
這就是臨床上所謂的潛伏期，受感染者看起來沒有病兆，但我們進一步研究後發現，這段期間病毒其實並非蟄伏不動，它們仍然繼續分裂滋長，只是程度很低。
