That reduced chances of reinfection by about 80 percent.

这使得再感染几率降低了约 80%。

Or whether people will be more susceptible to reinfection with XBB?

或者人们是否更容易再次感染 XBB？

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

这显然是一个大问题。以及再感染风险大吗？

And it's actually repeated cycles of reinfection that can cause the most damage.

实际上，反复感染循环才是造成最大伤害原因。

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

天，我们要讨论对于 BA. 5 再感染了解。

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

因此比较不同变再感染风险有点难。

Researchers in the United States have reported the country's first confirmed case of coronavirus reinfection.

美国研究人员报告了该国首例冠状病毒确诊病例患者再次感染。

There have been more than 37 million cases of coronavirus and only a handful of proven reinfections.

目前有超过3700万例冠状病毒感染病例，只有少数被证实再次感染。

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 再感染现在确更常见了？

Their key conclusion is that from this study of monkeys, reinfection could not occur if the monkeys had neutralizing antibody.

这项研究得出关键结论是，如果猴子体内有中和抗体，再次感染就可能不会发生。

Some may have had undetected mild or asymptomatic reinfections.

有些人或许是未检测出轻症或无症状再感染。

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

关于再感染率真实世界数据也将更清楚地表明免疫力变化程度。

The World Health Organization said on Saturday there is no evidence that people who have recovered from COVID-19 are protected against reinfection.

世界卫生组织周六表示，没有证据表明新冠肺炎康复人不会再次感染。

Studies by Discovery Health, South Africa's largest insurer, showed that people who contracted the Delta variant faced a 40 percent risk of reinfection with Omicron.

南非最大保险公司 Discovery Health 研究显示，接触过德尔塔人有40%风险会再次感染奥密克戎。

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.

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

When you talk about reinfection, and you don't keep in the concept of variants, that's an entirely different ball game. That's a good reason for a mask.

当出现二次感染时，如果你还没有“变”这样概念，那就完全是另一回事了。这就是戴口罩理由。

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针，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。

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.

我们看到再感染 BA. 5 病例增多，部分归因于其免疫逃避——刺突蛋白内变帮助病毒回避先前变抗体。

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.

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

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

对比感染过旧变人，感染过初代奥密克戎变 BA.1 人，被新奥密克戎新亚感染几率更高。
