What is the reason for the spread of the “Delta” mutant much faster than other strains of Corona?


Health experts consider the delta mutant to be the main factor in the alarming increase in cases of the coronavirus, the most contagious version of the virus that we have seen throughout the entire pandemic.

    The delta mutant may travel faster than other strains because it makes more copies of itself inside bodies at a faster rate.

Worldwide, there is an alarming increase in coronavirus cases, and health experts say the main factor in this latest wave is the highly contagious delta mutant.

The “delta” mutant spreads about 55 percent faster than the “alpha” strain of the Corona virus that first appeared in the United Kingdom late last year, according to the World Health Organization, and this strain spreads about 50 percent faster than the version that began infecting people in late 2019.

The “Delta” strain first appeared in India in December 2020, and quickly became the dominant variant of the Corona virus, overwhelming the country’s health care system.

For his part, Ashish Jha, dean of the School of Public Health at Brown University, USA, said: “This is the most contagious version of the virus that we have seen throughout the entire pandemic,” stressing that “it is really very contagious.”

And on July 2, the American newspaper “New York Times” said that after a year and a half since the Corona virus began to spread around the world, Injuries are back again in large swaths of the world, largely driven by mutant, especially the highly contagious delta mutant first identified in India.

The spread of the “Delta” mutant in all 50 US states

The first case of the “delta” mutant was identified in the United States last March, and by early July, it accounted for more than half of the cases that were tested for “Covid-19” in the country.

The “delta” mutant now accounts for 83% of coronavirus cases in the United States, according to the US Centers for Disease Control and Prevention.

The average daily new cases this week are up 55 percent from last week, with cases rising in 46 states as of Tuesday, according to data from Johns Hopkins University.

One study suggests that the delta mutant may be transmitted faster than other strains because it makes more copies of itself in our bodies at a faster rate.

“For unvaccinated people, they are infected through exposure for a much shorter period of time,” Jha added.

Vaccines available in the United States have proven effective against the “delta” mutant. Although there have been cases of vaccine breakthroughs, people who are fully vaccinated rarely become severely ill.

But less than half of the US population is fully vaccinated, according to data from the Centers for Disease Control and Prevention, which warns of an “unvaccinated pandemic”.

On Sunday, Murthy noted that 99.5% of deaths were among the unvaccinated, noting that vaccinating people as soon as possible, “is the fastest and most effective way out of this pandemic.”
