NEW DELHI: The mortality rate is one of the effective ways of measuring the extent of damage caused by the novel coronavirus pandemic. The mortality rate is defined as — number of deaths divided by the number of confirmed cases. According to John Hopkins University & Medicine, the difference in mortality rate across the countries could be due to the following reasons —
Differences in the number of people tested: Extensive testing ensures better tracking of the virus and thus ensuring there are no unreported deaths from the virus. This lowers the case-fatality ratio.
Demographics: If the population has a higher percentage of older people, the mortality rate is likely to be higher.
The healthcare system: For example, mortality may rise as hospitals become overwhelmed and have fewer resources.
Other factors, many of which remain unknown.
The number of coronavirus deaths is measured against two factors — confirmed cases or a country's/region's population. We look at the number of deaths per 100 confirmed cases for 20 most-affected countries.
