This means not all cases are known all the time, which could significantly alter the death rate as it is presented here. Countries like Norway and the Netherlands, for example, recommend people with non-severe symptoms to just stay at home. Second, not all people go to see (or can see, due to testing capacity) a doctor when they have mild symptoms. Germany, for example, started testing relatively early once the country’s first case was confirmed in Bavaria in January 2020, whereas Italy tests for the coronavirus postmortem. First, countries worldwide decide differently on who gets tested for the virus, meaning that comparing case numbers or death rates could to some extent be misleading. People are right to ask whether these numbers are at all representative or not for several reasons.

Examples are these statistics on the confirmed coronavirus cases in Russia or the COVID-19 cases in Italy, both of which are from domestic sources. Note that Statista aims to also provide domestic source material for a more complete picture, and not to just look at one particular source. In this statistic, these separately reported numbers were put together. In some cases, like China, the United States, Canada or Australia, city reports or other various state authorities were consulted. For the majority of countries, this is from national authorities. The numbers shown here were collected by Johns Hopkins University, a source that manually checks the data with domestic health authorities. The source seemingly does not differentiate between "the Wuhan strain" (2019-nCOV) of COVID-19, "the Kent mutation" (B.1.1.7) that appeared in the UK in late 2020, the 2021 Delta variant (B.1.617.2) from India or the Omicron variant (B.1.1.529) from South Africa. By April 26, 2022, the virus had infected over 510.2 million people worldwide, and led to a loss of 6.2 million. Note that death rates are not the same as the chance of dying from an infection or the number of deaths based on an at-risk population. This according to a calculation that combines coronavirus stats on both deaths and registered cases for 221 different countries. COVID-19 rate of death, or the known deaths divided by confirmed cases, was over ten percent in Yemen, the only country that has 1,000 or more cases.
