But their presence in the nasopharynx is especially important, as that's where respiratory viruses like SARS-CoV-2 usually enter our bodies, and where scientists believe these viruses can hang out and multiply.

但他们在鼻咽中存在则尤为显著，因为像新冠病毒这样呼吸道病毒通常是通过鼻咽进入我们身体，而科学家们则认为是因为病毒能在此逗留繁殖。

To perform RT-PCR, some of the extracted sample from the nasopharyngeal swab is added to a solution containing an enzyme called reverse transcriptase, nucleotides and primers that are complimentary to a specific SARS-CoV-2 target sequence.

RT-PCR步骤是：首先将鼻咽拭子部分样本加入到含有逆转录酶、核苷酸引物液中，其中引物将与SARS-CoV-2病毒目标序列互补。

The facial nerve also innervates the sublingual and submandibular glands, which secrete saliva, as well as the lacrimal gland which produces tears, and mucous membranes of the nose, mouth, and nasopharynx.

面神经同时也支配着舌颌，它们可以分泌唾液；以及产生眼泪泪，还有口、鼻、鼻咽粘膜。

Upon entering the body, the virus encounters the epithelial cells lining the nasopharynx which is the part of your throat nearest your nose.

病毒进入体内后会遇到鼻咽部上皮细胞；鼻咽指是喉咙靠近鼻子部位。

To enter Japan, travelers need to get a certificate that proves negative results for COVID-19 from nasal swab testing or saliva samples.

入境日本旅客需持有鼻咽或唾液样本新冠病毒检测呈阴性证明。

You're probably familiar with some of the many weapons in the innate immune system's arsenal, like your skin and the mucus in our nose and throat.

你可能对先天免疫系统武器库中许多武器很熟悉，比如你皮肤鼻咽部黏液。

The full genome sequences from oropharyngeal and nasopharyngeal specimens were identical to one another and were nearly identical to other available 2019-nCoV sequences.

来自口咽鼻咽标本全基因组序列彼此相同， 并且与其他可用 2019-nCoV 序列几乎相同。

Serum specimens for both collection dates were negative for 2019-nCoV. Nasopharyngeal and oropharyngeal specimens obtained on illness days 11 and 12 showed a trend toward decreasing levels of virus.

两个采集日期血清标本均为 2019-nCoV 阴性。 在患病第 11 天第 12 天采集鼻咽口咽标本显示病毒水平呈降趋势。

Both upper respiratory specimens obtained on illness day 7 remained positive for 2019-nCoV, including persistent high levels in a nasopharyngeal swab specimen (Ct values, 23 to 24).

在患病第 7 天获得两份上呼吸道标本仍呈 2019-nCoV 阳性， 包括鼻咽拭子标本中持续高水平（Ct 值， 23 至 24）。
