I saw! Hope they keep up!

I mean, when people fly, its often for vacations paid and planned a while in advance and being rejected last minute because they tested positive would ruin plans and cost a lot of money. If you want the economy to start again and tourism to be back to pre pandemic levels you're gonna have to move on eventually.

Good point; i guess I was exaggerating. XBB is taking over and avoiding immunities quite well, but the consequences are not fully understood and you may be right that the actual impact is actually limited.

Why? To protect the world of a new variant? XBB is wreaking havoc in the US, should the world mandate that US travellers test negative? How about wearing a mask and staying up to date with vaccines ?

Edit : by the way I do agree China's stance on data is unacceptable and stats / virus sequencing must be shared to the world
