The Omicron wars: Can we really afford to lock down again? In response to the new omicron variant first discovered by South African scientists, many countries have reintroduced pandemic travel restrictions that we thought were long behind us. Israel and Morocco have banned all foreign visitors, while tougher rules on quarantining and travel have also been enforced in the UK, Australia, Singapore and parts of Europe. Meanwhile, travelers from southern African countries have been banned from entering almost everywhere. Scientists say that it is still too early to say how infectious the new variant is, or how resistant it might be to vaccines. This disruption comes just as many economies were starting to reopen after more than 20-months of pandemic closures and chaos. The new restrictions are already triggering a fierce debate: some say that we are now in the endemic stage of the pandemic and that it is both unsustainable – and economically and psychologically harmful – to keep locking down every time a new variant surfaces. Others, like Israel's PM Naftali Bennett, say we are in the throes of a new "state of emergency," and that we can't afford to take any chances. What do you think?
