Coronavirus pandemic : New variants and new fears

World has definitely not  turned over the  Coronavirus pandemic’s page. It is still an item of big concerns. We all remember the start of the pandemic and the  huge slaughter it has made all around the world.The  WHO and all governments of all countries have made big decisions and taken strong resolutions to slow down the virus’s terrific spread. Little by little, drastic measures have shown  encouraging results. But as hearts  gradually calm down, new threats and new fears are born, due to new variants of the virus.

The same strain

It is the same Wuhan SRAS-CoV-2 that continues spreading all around the world. But from 2019 to 2021, the chinese strain has changed a lot. It has strengthened and mutated rapidly into new variants more virulent and resistant.

New variants

According to the WHO, they are some 145 strains that are spreading fast all around the world. First new variants  have appeared in ending 2020. In Mexico, scientists have located the B.1.1.7 variant. This one contains a set of 53 mutations.  In South-Africa, appeared two dangerous variants : the 501Y.V2 and the B.1.351. The same 501Y.V2 has also been located in the UK and another in the same country,the B.1.1.7 that is mutating and spreading again and again to others countries. Various contaminatons to the B.1.1.7. mutant  have been reported in the USA. The P.1 variant recently emerged in Brazil.

We all agree that the revival of the virus is not a good news at all. It’s time to be more cautious than we have been since the pandemic  began. New variants are going to be very difficult to fight against. Their virulence and resistance are impressive and terrifying. Very fortunately, scientists are working hard to retaliate. Pfizer, Moderna, AstraZeneca, Sputnik V vaccines are giving hope and are showing their effectivness.  Hopefully vaccination’s campaign will extend to most people possible.
