Brazil, again the gateway

Brazil, one of the countries in the world most affected by COVID-19, was also the gateway for the coronavirus in Latin America, with the first case registered on February 26, 2020, and was also the place of origin of the “Variant of concern” known as gamma or P.1, emerged in the state of Amazonas (north).

Now, in an attempt to avoid a new wave, the Brazilian Government suspended since last Monday flights from South Africa, Botswana, Eswatini (formerly Swaziland), Lesotho, Namibia and Zimbabwe, and is considering extending that measure to Angola, Malawi, Mozambique and Zambia.

Many questions

It is suspected that it may be more contagious due to the high number of mutations (30) it has in the spike (spike), which the virus uses to infect human cells, but it is not known if it causes serious illness and if it reduces the effectiveness of vaccines current.

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.
