What is Coronavirus disease (COVID-19)?
Coronaviruses (CoV) are a large family of viruses that cause illnesses ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
- This is an infectious disease caused by the SARS-CoV-2 virus.
This visualization shows the recorded number of confirmed cases and deaths over time in over 3000+ locations. The data for reported confirmed cases (yellow) and deaths (black) is displayed as concentric circles for all countries, and on a state and county level where available. We have removed the metric from the first version of this COVID-19 tracker.
The size of the circle represents the number of cases in one location. In the panel on the left, you can choose a country from the drop-down menu, see a total global number of confirmed cases and deaths as well as see the daily new cases and new deaths. By selecting a country, the view of those numbers will represent the situation for the chosen geography. Data is currently available on the following zoom levels: State/province level - US, Germany, Italy, Vietnam, United Kingdom, Spain; County level for the US; Country level - other countries. COVID-19 spread timeline The timeline in the left-hand side panel represents the spread of the virus in the past weeks and months. With the help of the controller, you can navigate through time and display the reported cases and deaths for a given date. The data can be seen as a curve of total confirmed cases and daily reported cases – on a global and country level.
COVID-19 tracker data sources On a global level, this tracker visualizes data from ECDC. For the US, the map shows data from The New York Times, based on reports from state and local health agencies. For Germany, the map shows data from Robert-Koch Institute and ZEIT ONLINE compiled by Jan-Philip Gehrcke. For Italy, the tracker shows data from the Sito del Dipartimento della Protezione Civile. For Spain, the tracker shows data from the Spanish Health Ministry compiled by Sequoias. For Vietnam, the subnational level data is provided generously by HAPRI. For the United Kingdom, data has been compiled by Tom White. Please note: The use of different datasets may result in a potential mismatch between global, national, and subnational numbers. Comparisons: Every year an estimated 290,000 to 650,000 people die in the world due to complications from seasonal influenza (flu) viruses. This figure corresponds to 795 to 1,781 deaths per day due to the seasonal flu. SARS (November 2002 to July 2003): was a coronavirus that originated from Beijing, China, spread to 29 countries, and resulted in 8,096 people infected with 774 deaths (fatality rate of 9.6%). Considering that SARS ended up infecting 5,237 people in mainland China, Wuhan Coronavirus surpassed SARS on January 29, 2020, when Chinese officials confirmed 5,974 cases of the novel coronavirus (2019-nCoV). One day later, on January 30, 2020, the novel coronavirus cases surpassed even the 8,096 cases worldwide which were the final SARS count in 2003. MERS (in 2012) killed 858 people out of the 2,494 infected (fatality rate of 34.4%).
