Case Studies In COVID-19 Control

When COVID-19 burst on the scene early last year, it caused a panic. Its mode of transmission was not well understood, fatality rates were much higher than seasonal influenza, and vaccines were far off. The level of uncertainty provoked very tight public health restrictions.

A year and half on, we know quite a bit more about how COVID-19 behaves, and vaccination is a reality. Yet public health policies across countries have diverged significantly, as have their economic fortunes. The following case studies will be instructive as the world strives to “learn to live with the virus.”

The United Kingdom has had a wide range of experiences with COVID-19 in the last year and a half. Initially, the government was reluctant to implement restrictions, relying on predictions that herd immunity would be naturally acquired. That proved to be a major miscalculation, but officials quickly recognized their error and pivoted to an aggressive vaccination program. Two-thirds of the British population has been fully vaccinated.

The government lifted almost all restrictions related to COVID-19 in June. Economic activity has surged; real gross domestic product (GDP) is expected to expand at a 7% annual pace in the third quarter. Cases have remained elevated, but hospitalizations and fatalities are well down from their peaks of earlier this year.

Countries have taken a wide range of approaches to coping with COVID-19.

New Zealand, by contrast, took a zero tolerance policy toward COVID-19. This tack produced early success, with very low case counts. But even the slightest increase in infection has provoked renewed lockdowns. New Zealand’s real GDP is set to decline by 7% in the third quarter, and the on-again, off-again pattern of restrictions frustrated residents.
