Translation of "virulence" into Chinese

Had the virus mutated to a more virulent form, we would not be talking about forging ahead.

倘若病毒变异,毒性更强,我们将谈不上稳步前进。

My healthy cells are being displaced by malignant cells of incredible virulence.

我 的 健康 细胞 正 流离失所 由 恶性 细胞 的 令人 难以置信 的 毒力 。

According to an article in the journal Clinical Infectious Diseases, “virtually all of the contagious virulent infections” can be spread by international travelers.

正如《临床传染病》期刊(英语)的文章所说,“几乎所有病毒性传染病”都可以通过国际游客传播。
