这几天决定把圣诞期间的去欧洲的旅行计划取消了，还是在美国境内开车在附近走走吧。有点担心别到时候万一没法入境了。 从12/6 起，CDC正式要求2岁以上all air passengers入境美国，不管有没有打过疫苗，都需要提供, proof of negative Covid-19 test or documentation of recovery from Covid-19 for all air travel。 https://www.cdc.gov/coronavirus/2019-ncov/travelers/testing-international-air-travelers.html
What You Need to Know If you plan to travel internationally, you will need to get a COVID-19 viral test (regardless of vaccination status or citizenship) no more than 1 day before you travel by air into the United States. You must show your negative result to the airline before you board your flight. If you recently recovered from COVID-19, you may instead travel with documentation of recovery from COVID-19 (i.e., your positive COVID-19 viral test result on a sample taken no more than 90 days before the flight’s departure from a foreign country and a letter from a licensed healthcare provider or a public health official stating that you were cleared to travel).

都能，要有专门谈判保证结果。中国大使馆的不就是当天就出结果吗，12小时左右，还是核算和抗体都测呢。这样子中国以后估计要24小时了，而且有美国的为例，更加紧张啊
美国机场有当天出结果的testing site. 这2天做了下研究，可以用自我测试的套装，海关认可的有3种好像， Qured， eMED, Optum
國內旅遊 甚麼都不查 只填一份簡單的聲明書 中招已康復的還是可以坐在你身旁 自由心證 最近飛機都蠻滿的
没有，上个月看松了些，打过疫苗提供三天内检测结果就行，没打疫苗的一天内。变种出现后又缩紧了。
今年秋天开始小孩每周约的PCR都是24小时内出结果
