Again, that's obviously a big question and how about the risk of reinfection.

这显然是一个大问题。以及再感染的风险大吗？

Some may have had undetected mild or asymptomatic reinfections.

有些人或许是未检测出的轻症或无症状再感染。

People with a previous infection reduced their risk of a new infection by about 50 percent.

先前感染者的再感染风险降低至约 50%。

That reduced chances of reinfection by about 80 percent.

这使得再感染的几率降低了约 80%。

Today, we're going to discuss what we really know about BA. 5 reinfection…

今天，我要讨论对于 BA. 5 再感染的了解。

And people who had just the original two-shot regimen had a similar risk.

打过初始两的人，再感染风险也差不多是 50%。

So it's a bit hard to compare the risk of reinfection with different variants.

因此比较不同变异株的再感染风险有点难。

Are those just stories, or is reinfection really more common now, with the BA. 5 variant running around?

这只是些传言吗，还是随着 BA. 5 再感染现在的确更常见了？

You're safe from re-infection, 99.9 percent of the time.

99.9%的情况下，你不会再被感染了。

And those nine people make three each one three other people smile.

那九个人 每个人再用笑容感染三个人。

Now, no one gets smallpox anymore, all thanks to the vaccine.

现在，没有人再感染天花，这都要归功于。

In other words, if you had Omicron in the winter or spring, you're fairly well protected against getting it again now.

换句话说，如果全年冬天或今年春天感染了奥密克戎，现在再感染的几率相当低。

Real-world data on reinfection rates will also give a clearer indication on the extent of any change in immunity.

关于再感染率的真实世界数据也将更清楚地表明免力变化的程度。

5 Did an infection that started in his fractured leg—added to the bone disease—cause his death?

5 他的骨折腿开始感染，再加上骨病，是否导致了他的死亡？

Those people had significantly more protection against reinfection with BA. 4 or 5: 76 percent against symptomatic infection, and nearly 80 percent against all infection.

感染过奥密克戎的防止再感染 BA. 4 或 BA. 5 的抵抗力大大增强：对有症状感染的防护率为 76%，而对所有新冠变异感染的防护率接近 80%。

But in general, if you've had COVID or gotten boosted recently, it is safe to say you probably have some protection against reinfection, and especially against severe outcomes.

但总体来看，如果你感染过新冠或最近接种了加强，可以肯定地说你有一定抵抗力防御再感染，尤其是防御重症。

People who had the original Omicron variant, BA.1, seem to have a higher rate of reinfection with these newer Omicron subvariants, compared with those infected with previous variants.

与感染先前变体的人相比，拥有原始 Omicron 变体 BA.1 的人似乎对这些较新的 Omicron 亚变体有更高的再感染率。

And Assumption Three: after people are infected for a while, they move to the removed group, since they've recovered, or sadly, died, and can't transmit the infection anymore.

在人被感染一段时间后，他会转移到转归组，因为他已经康复了，或者不幸的是，已经死了，不能再传播感染了。

The reason we're seeing more reinfections with BA. 5 is partly due to its immune evasiveness — mutations in its spike protein that help it sidestep antibodies to prior variants.

我看到再感染 BA. 5 病例增多，部分归因于其免逃避——刺突蛋白内的变异帮助病毒回避先前变异的抗体。

Another CDC study of a few hundred people in Kentucky, published in August, found that previously infected but unvaccinated people were twice as likely to get reinfected than were vaccinated folks.

8份发表的 CDC 的另一项研究观察了肯塔基州的几百人，发现比起已接种人士，既往感染但未接种人士的再感染率是前者的两倍。
