這種致命的新型冠狀病毒開始在美國(guó)蔓延

Across the US, scientists are trying to create a vaccine for the new virus. But don't expect it anytime soon.

在美國(guó)各地，科學(xué)家們正試圖制造一種針對(duì)這種新病毒的疫苗。但別指望很快就能實(shí)現(xiàn)。

The National Institutes of Health is working on one, but it will take at least a few months before clinical trials start and more than a year until a vaccine might actually become available.

美國(guó)國(guó)立衛(wèi)生研究院正在研制一種疫苗，但至少需要幾個(gè)月的時(shí)間才能開始臨床試驗(yàn)，一年多的時(shí)間才能真正研制出疫苗。

Separately, scientists in Texas, New York and China are also trying to create on a vaccine, said Dr. Peter Hotez, a vaccine scientist at Baylor College of Medicine in Houston.

另外，休斯敦貝勒醫(yī)學(xué)院的疫苗科學(xué)家彼得·霍特茲博士說(shuō)，德克薩斯州、紐約和中國(guó)的科學(xué)家也在努力研制疫苗。

But the challenge is daunting.

但挑戰(zhàn)是艱巨的。

"The lesson we've learned is coronavirus infections are serious and one of the newest and biggest global health threats," Hotez said.

霍特茲說(shuō):“我們得到的教訓(xùn)是，冠狀病毒感染是嚴(yán)重的，是最新和最大的全球健康威脅之一。”

What you can do yourself

你自己能做什么

Avoid close contact with anyone showing symptoms of respiratory illness, such as coughing and sneezing, the World Health Organization says.

世界衛(wèi)生組織說(shuō)，要避免與任何表現(xiàn)出呼吸道疾病癥狀的人密切接觸，比如咳嗽和打噴嚏。

Other symptoms of this coronavirus include fever and shortness of breath. Severe cases can lead to pneumonia, kidney failure and even death.

這種冠狀病毒的其他癥狀包括發(fā)燒和呼吸急促。嚴(yán)重的病例會(huì)導(dǎo)致肺炎、腎衰竭甚至死亡。

Scientists believe this coronavirus started in another animal and then spread to humans. So health officials recommend cooking meat and eggs thoroughly.

科學(xué)家認(rèn)為這種冠狀病毒開始于另一種動(dòng)物，然后傳播到人類。所以衛(wèi)生官員建議徹底煮熟肉和蛋。

Anyone with underlying medical conditions should avoid live animal markets and raw meats altogether, since those people are "considered at higher risk of severe disease," the World Health Organization says.

世界衛(wèi)生組織表示，任何有潛在健康問題的人都應(yīng)該避免活禽市場(chǎng)和生肉市場(chǎng)，因?yàn)檫@些人“被認(rèn)為有更高的嚴(yán)重疾病風(fēng)險(xiǎn)”。

What the US is doing

美國(guó)在做什么

The novel coronavirus is a public health emergency in the United States, said Alex Azar, secretary of the Department of Health and Human Services.

美國(guó)衛(wèi)生與公眾服務(wù)部部長(zhǎng)亞歷克斯·阿扎說(shuō)，這種新型冠狀病毒是美國(guó)的一種突發(fā)公共衛(wèi)生事件。

Once the health emergency declaration goes into effect at 5 p.m. ET Sunday, US citizens returning to the United States who have been in China's Hubei province in the two weeks before their return will be subject to up to 14 days of mandatory quarantine, officials said Friday.

官員們周五表示，一旦美國(guó)東部時(shí)間周日下午5點(diǎn)《衛(wèi)生緊急狀態(tài)宣言》生效，在回國(guó)前兩周曾在中國(guó)湖北省的美國(guó)公民將被強(qiáng)制隔離14天。

The development came a day after the State Department announced a highest-level warning urging citizens not to travel to China due to the outbreak.

在這一事態(tài)發(fā)展的前一天，美國(guó)國(guó)務(wù)院宣布了最高級(jí)別的警告，敦促公民由于疫情爆發(fā)而不要前往中國(guó)。
