We forbid travel for some countries, but not others. And we impose strict measures for incoming travellers/migrants for some countries, but not others.
Exactly. We don't have pandemic border control. What we have is a farcical joke pandemic border control.
Like I say, proper pandemic border control means restricted travel full stop. No matter which country going to and from, no matter what your nationality, passport, citizenship, or residency. (Genuinely) essential travel only (no exemptions for government chums) with real quarantine - as in all incoming travellers, no matter which country they're arriving from.
and for years to come
Do you not understand what temporary means? We're rolling out the vaccines. We might have to tweak some to tackle the UK, South African, and Indian strains, but we're getting there. We just need to get the majority of the population fully vaccinated. That won't be years.... unless we keep letting new strains in and allow them to spread, with the potential of developing vaccine resistancy before majority jabbed. Obviously border control would mitigate against that.
the poorer countries in the developing world are the ones most likely to have covid lingering around for years and years.
So far, the strict border control and proper quarantine many (but not all) of these countries have adopted has thankfully kept their cases very low. Good point about the poorer countries though. We owe it to them to take measures so that we don't allow yet another UK strain to spread misery around the world. We've already done it once.
