Is there an association between COVID-19 mortality and Human development index? The case study of Nigeria and some selected countries.

The worst performing countries with regards to CFR in descending order were Yemen (19.5%), Peru (9.0%) Mexico (7.6%), Sudan (7.4%) and Ecuador (6.3%) while the best performing nations were Bhutan (0.11%), Burundi (0.19%), Iceland (0.20%), Laos (0.21%) and Qatar (0.25%). The CFR of Nigeria was 1.39% which falls below the 50th percentile. Other comparison done showed significant difference in the CFR values between countries similar to Nigeria and countries that are dissimilar when HDI is used. (Mann-Whitney U test 126.0, p = 0.01). The trend of the CFR in Nigeria showed a steady decline and flattening of the CFR curve which does not seem to be affected by the spikes in the daily declared cases.
