serial monogamy

If serial monogamy is the norm, even if individuals have many partners over time, the virus is trapped within relationships and gets around slowly.

如果国家实行的是持续的一夫一妻制，那么即便一个人在不同时期拥有不同的性伴侣，病毒也只会在一定的人群中传播，传播速度因此相对缓慢。

We now call this "serial monogamy." I didn't know it was going to be this funny.

我们现在把它称作“系列一夫一妻制”。我不知道这个发现这么有趣。

Marriage in the United States tends to look more like serial monogamy than lifetime partnership, especially in the major city.

在美国，结婚越来越像是不断配对拆对重新组合的过程，而不是结成终身伴侣，在在城市尤其如此。
