Factors affecting the impact of COVID-19 | Commentary

 

By Hugh Holland

A meaningful evaluation of how well governments are managing the COVID-19 pandemic cannot be completed until the virus is under control in most countries. That is because the apparent outcome depends on where each country is on the curve. But some significant patterns are emerging. Here is a look at the data as of noon on May 5 and some of the factors that influence the numbers in G7 (denoted with **) and similar industrialized economies. The factors that shape the COVID-19 curve are a unique mix in each country. Most people would rank a low COVID-19 death rate as the most desirable outcome.

Existential factors (less affected by current management efforts)
• Median age and wealth – Deaths rates do not correlate well with median age and wealth.
• Population density – Physical distancing is more difficult in Asia, Europe, and in big cities.
• The nature of borders and trading patterns – European Union countries have open borders. Japan and South Korea are essentially island nations and their geography enables strict border control. Controlling the busy 6,000 km border between Canada and the USA is more difficult than island nations but less difficult than the 27 EU countries.
• The nature of travel patterns – People in wealthier industrialized G7 countries (that help support less-developed countries) travel more. Gateway cities, like London, New York, Chicago, Montreal, Toronto, and Vancouver are likely to be among the first affected.
• Culture – Japan’s long-standing tradition of strict hygiene and bowing instead of hand shaking is an advantage. Distrust of government is a disadvantage for some countries.

Management factors (more affected by current management efforts)
• Preparedness – Experts and supplies in place. Displaced in most countries by short-term priorities.
• Clear and consistent direction – Political leaders supporting scientific experts.
• Timing – The timing of effective mitigation relative to the outset is critical. South Korea was among the quickest to act on COVID-19.
• Testing – Testing reveals asymptomatic cases. Switzerland’s testing rate is 23 times Japan and their death rate is 52 times Japan. Testing should be helpful in directing mitigation strategies.
• Accuracy of reporting – While more than half of COVID-19 deaths in Europe and Canada have been in long-term care homes, these deaths have not been reported consistently in all countries. Many developing countries lack the ability to collect accurate data.
• Isolation – Physical distancing is proving to be one of the most effective albeit disruptive strategies.
• Herd immunity – So far, Sweden’s strategy of herd immunity (allowing large numbers to acquire some immunity by contracting mild cases of the virus) has not been a success story.
• Many of these same factors will also determine the success of each country and the world in actions to mitigate and adapt to climate change.

    Thank you Hugh for the information. We need factual sober information and the media don’t often devote enough time to providing it.
    There will doubtless be much analyzing and blaming once the crisis is over. It is necessary to get to the truth and if some are offended so be it. One thing this may have accomplished is to jar western nations from their complacent perches watching China orchestrate the dismantling of our society.
    I hope we learn from all this and don’t let the fear of appearing xenophobic deter us from corrective action where it is indicated.
    Much discussion ahead I have no doubt.

    It is interesting to note that the pandemic hit S. Korea on virtually the same day that it hit the U.S. Any dissertation on the massive difference in success would be redundant.

    Hugh, do you have even approximate numbers for N. Korea? I assume that they’re a state secret, like everything else. I understand that they had very little in the way of preventative items (although they refused them from China); and there are few doctors experienced in handling pandemics. Opposing that (and to their benefit) is the fact that they’re an extremely isolationist country.
