How does the health balance sheet look after one year of the pandemic? Well, 119m people (or just 2% of the world’s population) have been reported as infected, although if we include those who had no symptoms and those who did not report being ill, the figure is probably more like 15-20%. There have been 2.6m reported as having died of the disease. So that’s a case fatality ratio (CFR) of 2.2% globally. In some countries the CFR is way higher – Mexico’s CFR is close to 9%; Italy, the UK and South Africa CFRs are close to 3%. The variation is down to the age of those infected, the general health of the population and the resources and efficacy of the health systems in each country.
