The article I linked to mentions a substantial track and trace programme with a time frame from now until Xmas.
The countries you mention which haven’t eliminated the virus have had a track and trace programme over a shorter period than that.
Yes, New Zealand is smaller and locked down faster, but they have virtually eliminated the virus within a much shorter period. We share the feature of being an island nation.
I’ll also mention that for example Germany have found since easing lockdown that numbers have risen again, leading to a need to re-tighten lockdown.
So although Xmas seems a long way off now, realistically we are locking at a period of lockdown-ease-lockdown-ease potentially for much longer than that. Basically until a vaccine can be found. Which is next year at the earliest.
There’s no guarantee one will be found. There’s no guarantee “herd immunity” will be achievable either- we don’t know if immunity is conferred. And large numbers of people will die, and we will have allowed people to become infected with a virus about which we have no real idea of the long term consequences.
So lockdown, social distancing, masks in public, tight border controls/quarantine and a massive test and trace programme could well be much quicker than relying on herd immunity or vaccination.
In fact, the kind of approach New Zealand has taken is the only approach so far that has actually achieved anything tangible. Treatment, vaccination, herd immunity- no real results yet.
