A short study comparing countries on the quality of response to the Covid-19 pandemic

We estimate the overall quality of response to the Covid-19 pandemic in the first 18 months, using a small number of known parameters and a simple formula that is robust to the uncertainties in the data. The population-normalized values of deaths, diagnostic tests, confirmed cases, and doses of vaccines administered were considered. The average infection-fatality-rate provides us a baseline on potential deaths, and along with the test-positivity-rates in the formula, they add robustness to the estimates of the quality of response. The scores are used to rank countries in two lists representing 84 large countries with a population greater than 10 million, and 85 countries with smaller populations. Additional possible corrections in the rankings of countries to include the per capita purchasing power and the age distribution, are also shown. A few significant inferences are pondered that may help unravel the causes of the poor outcomes. In the last part of the manuscript, it is shown that the presented rankings are robust to the expected uncertainties in the data.
