Affected by the antibodies, the virus begins to diminish to the point where two weeks after the infection begins the majority of patients are almost completely free of the virus. Even if some virus genes remain, they are damaged or barely alive.
在抗體作用下，病毒數量開始減少，以致於發病兩星期後，大部分患者體內幾乎已檢測不到病毒；即使仍有病毒基因存在，也往往是殘缺不全或奄奄一息的。
