All viruses, including the one that causes covid-19, mutate. These tiny genetic changes happen as the virus makes new copies of itself. Most are irrelevant and some may even be detrimental to the virus’s survival, but others can make it more infectious or threatening to the host – humans.

COVID-19 has been a real puzzle to be deciphered day by day by medicine. And when least expected, new information comes with mutations and new developments related to the coronavirus. It happened in Manaus – Amazonas, in the last days. Doctors have reported a new variety of SARS-CoV-2, which causes COVID-19, with increased transmissibility caused by mutations in the virus, which has led more young people to death. Those on the front line are seeing an increase in the severity of the cases, and there are more serious injuries to the lungs, requiring immediate hospitalization and ventilation.

The new variant also affects younger people. As the new variants in the United Kingdom and in South Africa, the variants in Manaus show mutations in the genes that encode the spike. The British variant showed eight alterations and in the Manaus variant ten alterations were found in the spike protein. So, there is a concern that the current diagnostic tests of COVID-19 may present false negatives. Therefore, the variants raise doubts not only about the performance of diagnostic tests, but mainly about vaccines. It is essential to make the sequencing of more frequent active viruses, because only then will we be able to know whether vaccines adopted will have the same effectiveness in these variants. Experts say that vaccines can be redesigned and adjusted to better suit the virus in a matter of weeks or months, if necessary.

Therefore, it is essential to remind everyone of the individual responsibility in containing the spread of the virus and in the routine use M8, which keeps your innate immunity in good condition, in such a way that even if you become infected, you do not develop the serious form of COVID 19.
