The coronavirus has kept the scientific community on their toes with all new symptoms to find a safe and reliable vaccine. But as viruses tend to do,SARS-COV-2 itself has changed In the months when he started spreading around the world. Now,Anthony Fauci, MD, says there is something especially on the last mutation of Covid who worries him: "This could be a little more communicable."Read to find out how, and for more with faluk, checkDr. Faisci has just said the four words you were waiting to hear.

During a video interview with students and teachers from the College of Holy Cross on October 6, Fauci was asked about the differentStrains of the new coronavirus This existed now and if the mutations had made it more virulent or more difficult to develop an effective vaccine against.

He explained that theLast COVID mutation Could mean that the virus could now be able to spread more easily, claiming that "there is the hypothesis, although not completely proven, only if something is more communicable."

"When scientists have examined [the new mutation], they found that this new strain - which is now widespread in the world [afternight], it hit the original and in vitro tension, not yet in a person who replies better And more effectively binds to receptors on a variety of cultured cells, "says Fauci.

But the director of the National Institute of Allergy and Infectious Diseases (NIAID) also had a little good news, ensuring "there are no more virulent strains out there."

"The viruses, when they permeate society, rarely become more virulent. In general, they become less virulent because they adapt to greater transmissibility," said Fauci. "I'm just thinking that what you are going to see is that it might be a little more transmitted, at least depending on the binding of the receivers, but we need to look more physiologically."

Fauci's comments save recent resultsThe newly mutated strain of COVID-19 is probably more contagious, although less mortal than the original. Scientists even think that the mutated virus could help produce better immune responses in patients. The strain is not so radically modified that it prevents vaccinating.

The mutation "ismake more infectious particles, "Jeremy Luban, MD, a virologist at the University of Massachusetts Medicine School in Worcester, told the newspaperNature. "We have to keep our eyes open to additional changes."

Now scientists say they need more experiences that reproduce the transmission of the real world to verify these hypotheses on the last mutation of COVID. And for more information on the movement of the virus, checkThese are the states where Covid deaths are rising right now.
