Information Note
Last Updated: 3 Jul 2020

The WHO coronavirus disease (COVID-19) dashboard presents official daily counts of COVID-19 cases and deaths reported by countries, territories and areas. Through this dashboard, we aim to provide a frequently updated data visualization, data dissemination and data exploration resource, while linking users to other useful and informative resources.

Caution must be taken when interpreting all data presented, and differences between information products published by WHO, national public health authorities, and other sources using different inclusion criteria and different data cut-off times are to be expected. While steps are taken to ensure accuracy and reliability, all data are subject to continuous verification and change. All counts are subject to variations in case detection, definitions, laboratory testing, and reporting strategies between countries, states and territories. Other important considerations are highlighted under the respective Data Sources below.

The designations employed and the presentation of these materials do not imply the expression of any opinion whatsoever on the part of WHO concerning the legal status of any country, territory or area or of its authorities, or concerning the delimitation of its frontiers or boundaries. Dotted and dashed lines on maps represent approximate border lines for which there may not yet be full agreement.

From the 31 December 2019 to the 21 March 2020, WHO collected the numbers of confirmed COVID-19 cases and deaths through official communications under the International Health Regulations (IHR, 2005), complemented by monitoring the official ministries of health websites and social media accounts. Since 22 March 2020, global data are compiled through WHO region-specific dashboards (see links below), and/or aggregate count data reported to WHO headquarters daily.

Counts reflect laboratory-confirmed cases and deaths, based on WHO case definitions unless stated otherwise (see Country, territory, or area-specific updates and errata), and include both domestic and repatriated cases. Case detection, definitions, testing strategies, reporting practice, and lag times (e.g. time to case notification, and time to reporting of deaths) differ between countries, territories and areas. These factors, amongst others, influence the counts presented with variable under or overestimation of true case and death counts, and variable delays to reflecting these data at a global level.

All data represent date of reporting as opposed to date of symptom onset.

All data are subject to continuous verification and may change based on retrospective updates to accurately reflect trends, changes in country case definitions and/or reporting practices. Significant data errors detected or reported to WHO may be corrected at more frequent intervals. Major updates to country data are noted in: Country, territory, or area-specific updates and errata.

New case and death counts: Counts of new cases and deaths are calculated by subtracting previous cumulative total counts from the current count. These counts are updated incrementally throughout the day as more information becomes available. Daily new case and deaths counts are complete by 23:59 CET/CEST each day. Due to differences in reporting methods, cut-off times, retrospective data consolidation and reporting delays, the number of new cases may not always reflect daily totals published by individual countries, territories or areas. Due to the recent trend of countries conducting data reconciliation exercises which remove large numbers of cases or deaths from their total counts, such data may reflect as negative numbers in the new cases / new deaths counts as appropriate. This will aid users in identifying when such adjustments occur. When additional details become available that allow the subtractions to be suitably apportioned to previous days, data will be updated accordingly.

Current day counts, global epidemic curves and trends: Due to the incremental updates to the dashboard, global case and death counts visualised for the current day may reflect partial data until counts have been fully updated for all regions that day. This must be taken into consideration when interpreting global epidemic curves and trends.

Time stamps and updates: Time/date stamps reflect when the data was last updated by WHO. Due to the time required to process and validate the incoming data, there is a delay between reporting to WHO and the update of the dashboard. To account for different time zones across WHO Regions and data transmission methods, and improve the timeliness of data availability, updates to the global dashboard are applied three times per day.

Counts and corrections made after these times will be carried forward to the next reporting cycle for that specific region. Delayed reporting for any specific country, territory or area may result in pooled counts for multiple days being presented, with a retrospective update to counts on previous days to accurately reflect trends. Significant data errors detected or reported to WHO may be corrected at more frequent intervals.

Other: cases and deaths reported from international conveyances, included in global totals but not reflected in epidemiological curves as not associated with a country or region.

Transmission classification

Transmission classification is based on a process of country/territory/area self-reporting. Classifications are reviewed on a weekly basis and may be revised as new information becomes available. Differing degrees of transmission may be present within countries/territories/areas. For further information, please see: Considerations for implementing and adjusting public health and social measures in the context of COVID-19.

WHO has defined four transmission scenarios for COVID-19:

  1. No (active) cases: No new cases detected for at least 28 days (two times the maximum incubation period), in the presence of a robust surveillance system. This implies a near-zero risk of infection for the general population.

  2. Imported / Sporadic cases: Cases detected in the past 14 days are all imported, sporadic (e.g. laboratory acquired or zoonotic) or are all linked to imported/sporadic cases, and there are no clear signals of further locally acquired transmission. This implies minimal risk of infection for the general population.

  3. Clusters of cases: Cases detected in the past 14 days are predominantly limited to well-defined clusters that are not directly linked to imported cases, but which are all linked by time, geographic location and common exposures. It is assumed that there are a number of unidentified cases in the area. This implies a low risk of infection to others in the wider community if exposure to these clusters is avoided.

  4. Community transmission: Which encompasses a range of levels from low to very high incidence, as described below and informed by a series of indicators described in the aforementioned guidance. As these subcategorization are not currently collated at the global level, but rather intended for use by national and sub-national public health authorities for local decision-making, community transmission has not been disaggregated in this dashboard.

    • CT1: Low incidence of locally acquired, widely dispersed cases detected in the past 14 days, with many of the cases not linked to specific clusters; transmission may be focused in certain population sub-groups. Low risk of infection for the general population.

    • CT2: Moderate incidence of locally acquired, widely dispersed cases detected in the past 14 days; transmission less focused in certain population sub-groups. Moderate risk of infection for the general population.

    • CT3: High incidence of locally acquired, widely dispersed cases in the past 14 days; transmission widespread and not focused in population sub-groups. High risk of infection for the general population.

    • CT4: Very high incidence of locally acquired, widely dispersed cases in the past 14 days. Very high risk of infection for the general population.
