WHO Health Emergencies Programme
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, vaccination strategy, and reporting strategies.
Other important considerations are highlighted under the respective Data Sources below.

| COVID-19 case and death data | 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 is compiled through WHO region-specific dashboards, and/or aggregate count data reported to WHO headquarters. Counts primarily reflect laboratory-confirmed cases and deaths, based upon WHO case definitions; although some departures may exist due to local adaptations. Counts 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. New case and death counts from the Region of the Americas Rates |

| COVID-19 vaccination data | COVID-19 vaccination data are collected via WHO regional office-specific systems for monitoring COVID-19 vaccination uptake. These data are pooled from numerous sources, including direct reports from Member States, WHO review of publicly available official data, or data collated and published by third-party sites. Data published by third-party sites have not been validated by WHO, and WHO cannot comment on accuracy or completeness. Differences in counts may occur compared to other sources, due to different inclusion criteria and data cut-off times.
