Because hCoV-19 mutates relatively slowly compared to some other RNA viruses, many mutations have little or no impact. However, some mutations or combinations of mutations have been associated with increased transmissibility, immune evasion, or changes in virulence — qualities that define variants of concern (VOCs) and variants of interest (VOIs) and that are included in this phylogenetic analysis according to WHO tracking variants updates.

WHO will utilize various sources to continue monitoring the COVID-19 epidemiological situation via the WHO COVID-19 dashboard. If data for certain countries is unavailable in this section, it may indicate that they have either ceased reporting COVID-19 surveillance data to WHO or have integrated the COVID-19 surveillance into existing respiratory disease surveillance. In the latter case, SARS-CoV-2 detections from sentinel and systematic virological surveillance sites in those countries may be found in the Circulation section which also includes information on SARS-CoV-2 variant circulation. This global summary of COVID-19 cases includes data on confirmed cases reported to WHO from the comprehensive COVID-19 case monitoring.
