Now, rhinovirus belongs to the picornaviridae family of viruses.

病毒属于小核糖核酸病毒。

On the other hand, rhinoviruses commonly infect the epithelium of the respiratory mucosa, which lines the nasal cavity.

另一方面，病毒通常会腔周围呼吸道粘膜上皮细胞。

This attachment allows for rhinovirus to be eaten, or endocytosed, into the host cell.

这种附着允许病毒被吞食或内吞进入宿主细胞。

Unlike other picornaviruses, rhinoviruses are acid labile.

与其他小核糖核酸病毒不同，病毒在酸性环境下不稳定。

The symptoms of a rhinovirus infection are actually those often associated with the " common cold" .

病毒症状实际上是经常与“普通冒”相关症状。

So rhinovirus transmission occurs through contact with infected respiratory secretions, like snot and aerosols, particularly from nose blowing or sneezing.

因此，病毒通过接触受呼吸道分泌物传播，如涕和气溶胶，尤其是擤涕或打喷嚏。

This wasn't Price's fault— no one at the time knew that rhinovirus had multiple subtypes.

这不是普莱斯错——当时没有人知道病毒有多种亚型。

Many common colds are caused by rhinoviruses that have a geometric protein structure called a capsid instead of a lipid membrane.

很多普通冒是由病毒引发，它有一种称为“衣壳”几何蛋白结构，而不是脂质膜结构。

The first attempt to create a rhinovirus vaccine was a success— but a short-lived one.

首次研制病毒疫苗取得了成功，但却是昙花一现。

Once rhinovirus has been introduced to the respiratory mucosa, it targets cell surface receptors expressed at the surface of nasal epithelial cells.

一旦病毒被进入呼吸道粘膜，它目标是在上皮细胞表面表达细胞表面受体。

If we could eliminate all rhinovirus infections, we'd be a long way towards curing the common cold.

如果我们能够消除所有病毒，那么我们在治愈普通冒方面还有很长路要走。

Not necessarily. Many common colds are caused by rhinoviruses that have a geometric protein structure called a capsid instead of a lipid membrane.

未必。很多普通冒是由病毒引发，它有一种称为“衣壳”几何蛋白结构，而不是脂质膜结构。

Soon afterwards, a rhinovirus outbreak spread throughout the kids.

不久之后，一场病毒爆发在孩子们中蔓延开来。

In 1957, William Price vaccinated 50 kids with inactivated rhinovirus and gave 50 others a placebo.

1957 年，威廉·普莱斯 (William Price) 为 50 名儿童接种了灭活病毒疫苗，并给另外 50 名儿童注射了安慰剂。

Here's one fact in our favor: a single family of viruses causes 30 to 50% of all colds: rhinovirus.

有一个事实对我们有利：一个病毒家族导致 30% 到 50% 冒：病毒。

But we have yet to create a broadly protective vaccine against rhinovirus, or any other virus that causes the common cold.

但是我们还没有研制出一种针对病毒或任何其他引起普通冒病毒具有广泛保护作用疫苗。

Now, because rhinovirus infections tend to be mild and self-limited, treatment typically centers on relieving symptoms and preventing other people from becoming infected.

由于病毒趋于轻度且自限，因此治疗通常集中在缓解症状和防止他人上。

These viruses are the same ones that cause the common cold like rhinovirus, coronavirus, influenza virus, respiratory syncytial virus- or RSV for short, and parainfluenza virus.

这些致病病毒与导致普通冒病毒相同，如病毒、冠状病毒、流病毒、呼吸道合胞病毒（简称RSV）以及副流病毒。

There are more than 200 cold viruses, the most common of which are rhinoviruses (from the Greek " rin-, " for " nose" ).

有 200 多种冒病毒，其中最常见是病毒（ 来自希腊语“ rin- ” ，意为“ 子” ） 。

And despite the small numbers, this was promising: the immune systems of vaccinated kids were successfully recognizing and responding to rhinovirus.

尽管数量很少，但这是有希望：接种疫苗儿童免疫系统成功地识别并应对了病毒。
