As of January 2022, the share of COVID-19 cases corresponding to the Omicron variant in Mexico amounted to over 90 percent of the country's analyzed sequences of the SARS-CoV-2 virus. A month earlier, this figure amounted to 60 percent of cases studied in the country. 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 based on its trasmisibility level.
An increasing amount of cases
In Mexico, the spread of the Omicron variant led the Latin American country to
reach over 5.6 million confirmed cases of COVID-19 by March 2022, with the surge of close to two million cases in a matter of four months. Never before since the start of the pandemic had there been so many cases recorded in such a short period of time in the country. During those months, approximately 30 thousand people died due to complications stemming from the disease, reaching 320 thousand deaths by March 2022.
A relatively low testing rate
Within the Latin American region, Mexico was the fourth country with the largest number of people infected, following Brazil, Argentina, and Colombia. However, the country is considered to have had a
relatively low testing rate. According to recent estimates, around 117 thousand tests per million people were reported in Mexico as of March 2022, one of the lowest COVID-19 testing rates among the countries most affected by the pandemic. In contrast, Peru reached over 836 million tests per million population.
