Scenario # 1 – The most effective lockdown procedures
If we followed the procedures adopted throughout much of the Far East that would provide the most optimistic or quickest timescale for Covid 19 ending.
China swiftly introduced wide ranging lockdown measures in the worst afflicted areas of the country, which if the official figures are accurate led to plunging infection rates and a return to near normal conditions by the end of March.
Likewise, South Korea has been able to keep the outbreak to minimal levels by the highly effective use of track and chase procedures, using phones and bank transactions.
An analysis by Imperial College London indicated that countries that acted in this way early on in the pandemic would have their economies almost back to full capacity by the middle of 2020. By the way you can start working online as easy as 123 check it here
The majority of countries did not act drastically or rapidly enough to have economies back in full swing that quickly.
Scenario # 2 – The most extensive or time delayed lockdown measures to Covid 19
The majority of nations fall into this scenario for tackling coroavirus, and a longer wait for ending lockdown and returning to normality. Most of these countries adopted extensive lockdown and social distancing after witnessing the rapid infection rates experienced in Italy.
The U K and to a lesser extent the Netherlands were originally going to have minimum restrictions in the hope that a herd immunity would develop. The British government changed it’s policy when thousands of Italians and Spaniards began to die every week.
That delay meant the U K has recorded the second highest numbers of deaths so far. Sweden is the nation that has stuck with the strategy of developing a herd immunity, though many medical experts think that is the wrong approach.
Some nations have had health systems that have come under severe strain, Spain, Northern Italy, and potentially Brazil. Some of the American states including New Jersey, New York and Michigan have also been stained at times.
Lockdown seemed to prevent health systems collapsing though if restrictions are taken down too soon then it could cause a disastrous second wave that would cause far more deaths, cause tougher lockdowns and gravely harm the world economy.
With such a scenario the virus would remain a serious threat till the end of the year and into 2021.
Scenario # 3 – No lockdowns and a catostrophic second wave
Now this would be the doomsday scenario, with Covid 19 spreading so far and so wide that all lockdown restrictions and social distancing measures fail to stop the infection rate reaching 8 to 10% within the global population causing the deaths of tens of millions of people.
Should such an outbreak cause the collapse of health systems across virtually all nations the toll could be even higher, particularly if a second wave was not prevented. Only the development of a successful vaccine would get rid of the virus.
One of the latest predictions in an American medical journal was that social distancing would have to stay in place nationwide well into 2022 unless a vaccine was developed sooner.
