Implications of Different Coronavirus Exit Strategies
View attachment 2710
1) Lockdown until a vaccine
Very difficult to maintain lockdown once case numbers shrink, let alone for 12-18 months. The economy could shrink by a third - which would mean millions unemployed for months, and huge permanent damage to the economy.
2) Ease off measures once case numbers fall
What we seem to have learned in recent weeks is that, without other tools, nothing except full lockdown works to prevent another jump in cases
3) 'Adaptive triggering' - switching measures on and off when cases rise/fall
This is essentially the default in any case. But it's little use. Imperial estimates lockdown would be needed 2/3 of the time. The health cost would be large and economic benefits minimal
4) 'Immunity permits' for people who've had the virus
If only 10% of the population have had CV19, it's hard to see a policy of keeping the other 90% in lockdown as fair or possible. Economic benefits minimal.
5) Weekly testing
Some have proposed a weekly testing regime for the entire country. This could work. But it's a huge logistical challenge. Viable within 6 months
6) Contact tracing and mass testing
App-based contact tracing combined with large-scale testing seems like the most plausible option that could be available within weeks. Singapore's TraceTogether app is anonymous and doesn't track location, but instantly alerts people at risk. For it to work we'd need high app coverage - the large majority of people - and easily-accessible testing. Currently Singapore's app appears only to have 20% take-up. Getting higher coverage shouldn't be hard if it's the only way out of lockdown
Conclusion
6 seems like best hope for exiting lockdown by summer. Combined with regional variation and continued strict rules for the most at-risk group

6 seems like the best option. They'd need to be on their definition of those most at risk though.
