The United States plans to ease travel restrictions on all fully vaccinated foreign visitors starting in November, the White House said Monday.

Fully vaccinated foreign nationals and American citizens returning to the United States from abroad will be required to take a pre-departure Covid-19 test within three days of their flight and show proof of a negative result before boarding.

They will also need to do a viral test three to five days after arrival.

美国政府9月20日宣布，将自11月开始对所有完成新冠疫苗接种的外国旅客放宽旅行限制。

完成疫苗接种的外国旅客和返回美国的美国公民将被要求在飞机起飞前72小时内进行新冠病毒检测，并须在登机前出示检测结果阴性证明，在到达美国后的3至5天内还须再次进行检测。

The US Centers for Disease Control and Prevention plans to issue a contact tracing order requiring airlines to collect information from US-bound travelers, including phone number and email address.

Airlines will be required to keep contact tracing information for 30 days.

美国疾控中心还计划发布接触者追踪令，要求航空公司收集前往美国的旅客信息，如电话号码和电子邮箱地址，并保留联系信息30天。

"Fully vaccinated," as per the CDC, includes those who have received not only the vaccines approved for use in the US but those listed for emergency use by the World Health Organization but have not yet received such approval in the US.

美国疾病控制与预防中心表示，美国在放宽的旅行限制中认可的新冠疫苗，不仅包括在美国授权通过的疫苗，还包括被世界卫生组织列为紧急使用但尚未在美国获得批准的疫苗。
