American health sources revealed that the “delta” mutated from the Corona virus has now represented about 83 percent of cases of the virus in the United States.
The Associated Press quoted Dr. Rochelle Walinsky, director of the US Centers for Disease Control and Prevention, as saying in a session of the US Senate today: “This number represents a significant increase from last June, when the alternative accounted for about 50 percent of cases of coronavirus infection, adding: “Vaccination is the most powerful tool we have to prevent the spread of coronavirus variants.”
It is reported that the delta variant is a mutated form of the Corona virus that spreads more easily than other copies and was first discovered in India, but its presence has now been determined worldwide.
