机票和旅馆都订好了，所有的vax certificates也都全了。现在就是不太清楚到了以后是不是需要做PCR，还是自己做个RAT测试就可以了？新加坡的网站上说后者就可以了Undergo an unsupervised self-administered ART using self-procured authorised ART kits within 24 hours of arrival in Singapore. This will replace the previous requirement for a supervised self-administered ART. 但今天旅馆又发来一封信，不知道什么意思： Greetings from Carlton Hotel Singapore! |
