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

这显然一个大问题。以及再的风大吗？

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

99.9%的情况下，你不会再被了。

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

那九个 每个再用笑容三个。

Some may have had undetected mild or asymptomatic reinfections.

有些或许未检测出的轻症或无症状再。

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

打过初始两针疫苗的，再风也差不多 50%。

" Some people are ending up with serious long-term health issues. We need to wake up to this reality and stop trivialising viral infections and understand that they are major drivers of chronic diseases."

“有些最终会出现严重的长期健康问题。我们需要清醒地认识到这一现实，不要再轻视病毒，要明白病毒慢性疾病的主要诱因。”

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.

在们被一段时间后，他们会转移到转归组，因为他们已经康复了，或者不幸的，已经死了，不能再传播了。

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，尤其防御重症。

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风有点难。

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月份发表的 CDC 的另一项研究观察了肯塔基州的几百，发现比起已接种士，既往但未接种士的再率前者的两倍。

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

先前者的再风降低至约 50%。

That reduced chances of reinfection by about 80 percent.

这使得再的几率降低了约 80%。

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.

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

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了奥密克戎，现在再的几率相当低。

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

这只些传言吗，还随着 BA. 5 再现在的确更常见了？

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

今天，我们要讨论对于 BA. 5 再的了解。

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

We're in these cycles of disruption and in fact, One of my colleagues has called 2020 the year of reinfection, because about 13% of our cases are people who've had it in the past.

我们正经历这些破坏周期， 事实上，我的一位同事称2020年为再之年，因为大约13%的病例之前已经过的。

Yeah, so just, there's studies that follow cohorts of people who are infected for a year, and the reinfection rate is something like somewhere between .

的，所以有一些研究跟踪了一年内群的队列，再率大约在0.3%到1%之间。

Or if we chop the probability of infection down by another factor of 2, for example meaning people practice better hygiene?

或者如果我们再将概率降低一半，比如们提高了卫生水平？
