Pandemic truce in Brazil

Ómicron’s landing occurs at a time when Brazil is experiencing a certain pandemic stability, with the number of infections and deaths at their lowest levels practically since the outbreak of the virus in the country, in February 2020.

This truce is mainly due to the progress of the vaccination campaign, which has allowed 75% of the 213 million Brazilians have a dose and 63%, the complete guideline.

However, the rebound in COVID-19 cases in Europe and the appearance of this new variant have put governors and mayors on alert, several of whom have canceled in recent days the festivities scheduled for the end of the year.

The mayor of Rio de Janeiro, Eduardo Paes, has not ruled out canceling the events and concerts scheduled to host 2022, which usually bring together millions of people in the iconic tourist beaches Rio de Janeiro capital.

Likewise, the carnival of 2022, the biggest festival of Brazilian society, is also in the air, amid alerts from health specialists, who recommend caution and maintain certain preventive measures, such as the mandatory use of a mask, until the true potential of the Omicron variant is discovered.
