Visualisation of the coronavirus case numbers. Heat maps displayed with age groups and calendar weeks per rural or urban district and federal state.
Below you will find an alphabetically sorted overview of all federal states and their rural and urban districts. LK stands for "Landkreis" (rural district) and SK for "Stadtkreis" (urban district). There are also heat maps for Germany (total).
A heat map is a diagram for visualising data using a two-dimensional definition set. In this case a matrix is used. The x-axis represents the timeline as calendar weeks and the y-axis represents the age groups. The values in the fields are the SARS-Cov2 infection cases laboratory confirmed by the health authorities, per 100,000 inhabitants. Low values appear green, high values are shown in yellow to red.
A positive PCR result does not automatically mean that the person has coronavirus disease 2019 (COVID-19). Various studies have shown that a relevant proportion of all laboratory-confirmed cases do not develop COVID-19-typical symptoms during the course of the infection. This percentage varies greatly depending on the quality of the study. However, it is currently assumed that about 20% of the patients are actually asymptomatic. It is important, however, that the viral load of asymptomatic individuals is comparable to that of COVID-19 patients. It is therefore assumed that symptomatic and asymptomatic people can be equally infectious.
