There is typically significant societal support to go from 10,000 to 1,000 or even 100 cases: individuals see their friends and family getting sick and governments fear political backlash from overflowing hospitals.
1/
But maintaining lockdown measures to get from 100 cases per day to 1 can seem unnecessary to individuals, businesses, and governments. However, failing to maintain the closure will allow cases to rise again.
2/
The key to complete the elimination process once the cases become low is achieving conscious recognition and public appreciation of the final stage of the process, the countdown to zero.
3/
The use of the Green Zone strategy makes this much more feasible, as local areas are rewarded for eliminating transmission locally. When an individual knows their neighborhood has new cases they can take restrictions seriously even if the country as a whole has very few.

Three main identified “variants of concern” with more rapid transmission, higher severity, and vaccine evasion have spread globally in recent months because travel restrictions were not sufficiently strong. Each can be considered like a new pandemic.
A new P.3 variant first found in Philippines has E484K spike protein mutation found in Brazilian P1 variant, associated to stronger receptor binding and lower vaccine efficacy, and the N501Y mutation found in the UK B117 variant also considered to increase transmissibility.

And....🥁...😬
Two cases of the Philippines P.3 variant have been detected in the UK.
Without travel restrictions the worst variants are everywhere. [When will they learn?]
India reported the year’s biggest daily increase in cases on Sunday, with 25,320 new cases. Maharashtra, the epicenter of the renewed surge is imposing new restrictions but not a new lockdown. Halfway measures are not sufficient for this pandemic.
Italy is having a rapid increase in cases and deaths. As always, the sooner action is taken the better. While Italy will be strengthening its region-based lockdowns, the way this will be done is critical for the next stage of the outbreak response.
A “red zone” strategy, where restrictions are strengthened as cases go up, and relaxed as cases go down is exactly the prescription for health and economic disaster through yo-yo lockdowns.

In contrast, a green zone exit strategy has been advocated by advisor to the Minister of Health, Riccardi Walter @WRicciardi
"To beat the virus, Italy must make a courageous choice: adopt the "No Covid strategy", which also includes a lockdown, the only one that allows you to get out of the "vicious circle" of "months of yo-yo between partial closures and reopening ".

"Walter Ricciardi, advisor to the Minister of Health for the Covid emergency and public health scholar, writes it in today's "Avvenire", explaining that "mass vaccination", while essential, "will take months if not years to guarantee adequate protection".

Denmark cases increased rapidly recently, likely due to new variants particularly the UK variant. Implemented measures are not adequate in this context and its advantageous geographic location on multiple islands and peninsula have not been exploited to stop imports.
Out of all Nordic countries, Denmark currently has the highest vaccination doses administered per 100 people. It even has the highest rate in the European Union.
However, Denmark recently suspended the use of AstroZeneca vaccine while the officials investigate reports of blood clots in people who received the vaccine
With 786 new cases (weekly average) for the entire country Portugal is only weeks away from 0 new cases.
Portugal cases down 95%+ from peak, lowest since September.
Deaths are also down significantly, more than 90%.
On March 11, the government will announce plans to ease the lockdown.
Will they opt for (1) a sector based relaxation, or (2) a Green Zone exit (geographic) strategy, relaxing only areas with cases controlled by contact tracing, to reach elimination?
