Covid-19 has spread across the planet, trapping billions of people while health services struggle to cope. Find out where the virus has spread and where it has been most deadly
The Covid-19 coronavirus has spread around the world after first emerging in China late last year and has been declared a pandemic by the World Health Organization. However, due to differences in testing, the number of cases in some countries may be understated.
Larger nations clearly seem to have a higher number of cases and deaths.
Although there are also other factors at stake, such as countries’ demographic profile; countries with ageing populations may be more affected because the disease is more harmful for the elderly.
A more accurate measure is the number of deaths. Certain countries, including the United States, Brazil, India, Mexico and the United Kingdom, have been struck with particular ferocity by the disease.
For most countries in the world, Johns Hopkins University releases data on cases and deaths (a notable exception is North Korea, which claims to have had no cases).
But JHU acknowledges that it collects data from many sources, some of which are inconsistent with each other. There are major gaps in how countries test and in how they record cases and deaths, even where selection is less controversial.
For example, Belgium attributes Covid-19 fatalities when the disease is a suspected cause, even when no test has been conducted.
