A few days after its discovery, the new strain of coronavirus SARS-Cov-2 originating in Great Britain could already circulate in Brazil, which raises greater concern when other researchers recently identified a new variant of the virus in the state of Rio de Janeiro, as the neighboring country goes through a second wave of infections that could even affect the rest of the countries from South America.
Claudio Mauerovich, former president of the National Health Surveillance Agency (Anvisa) between 2008 and 2014, assured today that the British mutation of the coronavirus strain “is certainly already circulating in Brazil” and stressed that it is necessary to follow the evolution of the new strain and its consequences in the rest of the world, but he also claimed that restricting only flights from the UK will not have great results since the new version of the virus has already left by various international routes.
However, the sanitarist, who today develops his activity within the Oswaldo Cruz Foundation, is recognized as the most “efficient” method of doing systematic surveillance of people arriving in Brazil from abroad, with testing and research and effective contact monitoring of these people.
The UK has been virtually isolated from the world since it announced last Friday that it had discovered a mutation in the covid-19 strain. Dozens of countries, including Argentina, have closed or severely restricted their airways to prevent this mutation from spreading at a time when everyone is preparing to start mass vaccinations against the original virus, the news agency published Tlam.
This is why the news that a group of researchers identified a new strain of coronavirus in the state of Rio de Janeiro, one of the regions hardest hit by the coronavirus pandemic.
Scientists have claimed that so far the new strain is “partially limited” to this city, the tourist capital of Brazil, but they have warned of the likely spread to the entire state and, therefore, to the rest of the country. “The significant increase in the frequency of this line (of the strain) raises concerns about public health management and the need for genomic surveillance during the second wave of infections ”, stressed the scientists of the study, developed under the coordination of researcher Ana Tereza Vasconcelos.
However, the study does not inform if the new identified strain is more transmissible or more aggressive than those already known in Brazil, which with more than 7.3 million cases is the third most affected country, after the United States and India, and the second in terms of the number of deaths from the disease, with more than 188,000, only exceeded – but from afar – by the United States. United.
Brazilian scientists have also claimed that there is no “proof” that this new strain can reduce the effectiveness of vaccines which are starting to be applied worldwide against the Covid-19 strain.
