Survey time period

December 2020 to July 2022

Special properties

considers only analyzed sequences of SARS-CoV-2

Supplementary notes

Results may not express the complete case variants in detail because only a share of proves are sequenced. New discovered variants and those actively monitored could be overrepresented due to targeting and difference on sequencing speed.

Omicron variants were reported since January 2022.

Citation formats

As of July 18, 2022, Omicron was the most prevalent variant of COVID-19 sequenced in Brazil. By that time, the share of COVID-19 cases corresponding to the Omicron BA.5 variant amounted to around 73.74 percent of the country's analyzed sequences of the SARS-CoV-2 virus. A month earlier this figure was equal to about 33 percent of the cases studied in Brazil. The Omicron variant of SARS-CoV-2 - the virus causing COVID-19 - was designated as a variant of concern by the World Health Organization in November 2021. Since then, it has been rapidly spreading, causing an unprecedented increase in the amount of cases reported worldwide.
