Are maps different in different countries?

The most important figures on the coronavirus by country and world region - and the impact on the stock market.
The most important figures on the coronavirus by country and world region - and the impact on the stock market.

A virus knows no national borders. The new coronavirus SARS-CoV-2 has already proven this at the beginning of the pandemic. The virus has been spreading since January, smaller than the pores of conventional respiratory masks. It does this internationally - along the vital arteries of our networked world: along the train, air and ship connections. And it spreads where we come together: in the offices, cafes, in the markets.

On this page we collect the latest figures on the global development of the coronavirus. They are automatically updated from various sources and are intended to provide a continuous overview. All figures for Germany, the counties and federal states can be found in this article.

All corona cases worldwide on an interactive map

Since the beginning of the pandemic, Johns Hopkins University in Baltimore has been collecting all confirmed cases in a global database. The map shows the reported new infections per country per 100,000 inhabitants. This makes it possible to see where the virus is currently spreading most strongly. The travel warnings come directly from the Federal Foreign Office, the risk areas are published by the Robert Koch Institute on its website.

The first known symptoms of the coronavirus appeared on December 1, 2019 in Wuhan, Hubei Province, China. From there it spread all over the world. If one compares the number of cases from other countries with each other, however, it must be noted that the number of cases from different countries are never comparable 1: 1. It is tested differently and the number of unreported cases can be very unequal.

Corona case numbers in an international comparison

The curves show the number of corona cases in the individual countries. For comparison, either click on a preset country group. Or you can use the “free choice” field to select countries that interest you. You can switch between total numbers since the start of the pandemic and the newly reported cases. You can also switch between absolute numbers and the values ​​per capita, change the period displayed and use a different scale. With the help of the country legend, the countries can be selected individually.

If the number of new infections increases sharply in a country, the daily deaths also increase with a time lag. These, too, cannot easily be compared in the individual countries. Because here, too, the states have different rules for which deaths are included in the official statistics. A high death rate can also not only be an indicator of high case numbers, but also that the health system in the country is overburdened - or has never been particularly good.

The development in the world regions

Viruses know no borders. A look at the regions of the world shows how evenly the virus has now spread around the world. The virus has taken root everywhere. Regional priorities can change again and again in the course of the pandemic.

Because more people live in Asia than in Europe, in Europe more than in Oceania and the absolute numbers cannot be compared one-to-one, one looks at the newly infected per 100,000 inhabitants for a better comparison.

After China in particular was badly affected at the beginning of the pandemic, Europe and the USA in particular were hit afterwards.

Which country in the world is most severely affected by the pandemic can change within a very short time if a particularly large number of new infections are reported in a few days.

[The handling of Corona is so different internationally that we regularly devote ourselves to countries and phenomena in individual analysis articles. We explain why Slovakia has just tested two thirds of the population, how Great Britain lost 15,000 cases to Excel, how Hungary failed with populist politics and how illogical it is to deal with domestic and foreign risk areas. This and more is available weekly in our country column for subscribers.]

The impact on the international financial market

The pandemic is affecting the economy in almost all countries. How serious the consequences could be has so far only been shown by forecasts made by experts. But what is already visible now is the development of the stock market.

Many companies had to revise their profit expectations downwards due to the pandemic. Things are looking particularly bad for airlines and tour operators. And so far it is difficult to predict when the pandemic will be over and the economy will recover. The fact that we have to work from home is mainly used by companies whose product helps us to do this, such as the video conferencing provider Zoom.

The development of a vaccine is hoping for an end soon. It's not a bad year, at least for listed pharmaceutical companies. Companies with promising vaccine candidates benefit in particular.

In this article we collect all important, current case numbers from around the world. Below you will find an overview of other research, analyzes and graphics that are particularly worth reading:

To the numbers and representations

Here we make it clear where the information and some of the ideas in this article come from. If you find errors or know better real-time data sources, please send us an email to [email protected]

Worldwide case numbers

Global data on infection cases are compiled from a variety of sources by the Center for Systems Science and Engineering at Johns Hopkins University in Baltimore, and visualized on a separate dashboard. We automatically obtain the data at regular intervals from the Github project, where the university offers the data for download. They are updated at irregular intervals. There may be delays until different countries have confirmed their cases and then passed them on.

Coronavirus case numbers in Germany

The case numbers in the counties and urban districts come from the respective websites of the counties as well as other official sources from the region, which update them at different intervals. Risklayer and the Center for Disaster Management and Risk Reduction Technology at the Karlsruhe Institute of Technology (KIT) collect these together with the Tagesspiegel Innovation Lab. You can find more detailed information here.

Information on those who have recovered

Not all countries report data on people recovering from Covid-19. In addition, different guidelines apply in the various countries as to when a sick person is considered to have recovered. For Germany, we use information from the districts and the Robert Koch Institute. Here an infected person is considered to have recovered after two weeks, if he is not in hospital or has died.

Details of the deceased

The reported number of deaths in Germany includes, on the one hand, those patients who died directly from the disease Covid-19. On the other hand, the information in Germany also includes people who had underlying illnesses and died with Covid-19, but for whom it cannot be clearly proven what the exact cause of death was. This can vary in the individual countries, so that these figures are only partially comparable.

Limitations of the data

Overall, how reliable these numbers are depends on many factors. For example, how quickly those affected go to the doctor, whether the virus is detected or how and when it is reported by the official bodies.

It can be assumed that the actual number of infected people is unknown, since, according to current knowledge, people can only have very mild symptoms even though they are infected with the virus. All details are therefore to be regarded as approximate values. Nevertheless, they give a significant impression of how the situation is developing in different parts of Germany and around the world.

Travel warnings

We obtain the travel warnings for the affected countries from the Federal Foreign Office. The Robert Koch Institute publishes the classification as risk areas on its website.


We continuously read data analyzes on COVID-19 from around the world and try to think further about the best analyzes and representations. We have collected some analyzes and visualizations worldwide on the coronavirus here, here and here.

For the presentation of the map of Germany in this article, we were inspired by articles from Zeit Online, the New York Times, Funke Interaktiv and numerous other visualizations.
