The Delta variant is now a ‘variant of concern’ of the coronavirus


the various concerns given the teaching of virus types that scientists believe are more susceptible or can cause more severe disease. Vaccines, treatments and tests that detect the virus may also be less effective against a variety of concerns. Previously, the CDC considered the Delta race to be a race of interest.
The CDC says Delta is different, which it used to be first identified in India, showed increased transmissibility, potential reduction in neuralization with some monoclonal antibody treatments under emergency clearance and potential reduction in neuralization from serum after vaccination in lab trials.
Covid-19 cases have been steadily declining over the past few months in the United States, but there are concerns that it could shift as the pace of vaccination and spread of the variety in the Delta slows. The CDC It is estimated that this is considered for 9.9% of cases in the US until June 5.
In a White House Covid-19 briefing last week, National Institute of Allergy and Infectious Diseases Director Dr. Anthony Fauci urged everyone to get vaccinated against Covid-19, pointing out that the Delta variety is in circulation in the United States at a rate similar to the tipping point seen in the UK, where the variety now dominates.

“We can’t allow that to happen in the United States,” said Fauci, who called the UK experience “so hotly debated” to be vaccinated.

The difference is believed to be responsible for the latest rise in cases in the UK and a study of cases in Scotland published on Monday found that it was associated with double the risk of hospitalization compared to Alpha’s variant, B.1.1.7, which was first identified in the UK.

The UK announced on Monday that the easing of coronavirus restrictions would be delayed by another four weeks, until July 19, after a rise in cases and, in particular, a growing spread of the genus in the Delta.

As of Sunday, the Delta variety is responsible for nearly 10.3% of U.S. Covid-19 cases, according to Drs. Eric Topol, the founder and director of the Scripps Research Translational Institute, that outbreak.info traces the variables throughout the plant disease.

Such is not so much, but the speed of its spread is a concern.

“It doubles every seven to 10 days, which means when it comes three weeks from now, this variation will prevail,” Topol said. “That means we have two or three weeks to just get away with vaccinations to stop this trend.”

Vaccination in general seems to be one that prevents races. For example, the Alpha strain is the dominant offense in the United States and ever since late April. But with exceptions like Michigan, it doesn’t cause case outbreaks in most parts of the country.

Topol said the U.S. has been able to “ante up” and “completely tilt the vaccine” with the arrival of the U.S. variant.

Most blue states will make the Biden vaccine goal on July 4. The reds didn’t win.

With the Delta variety, Topol is not as optimistic.

“It’s the most confusing variant by far, because it’s still 60% more contagious than the Alpha, so it’s a super spreader strain,” Topol said. But the vaccination rate has stalled.

While 43.9% in the US is fully vaccinated, according to the CDC, the rate of vaccination in humans is slowing.

In Mississippi, nearly 29% of the population is completely vaccinated. In Alabama it is below 31%. In Arkansas, no less than 33%. In Louisiana, Georgia, and Wyoming no less than 34%, according to CDC data.

Vaccines and varieties in the Delta

The good news is people are completely vaccinated seems to have strong defense against Delta race.
A study published in the Lancet found that one dose of Covid-19 vaccine was insufficient, but after the second dose, Pfizer-BioNTech provided 79% protection from the Delta variant. Compare that to 92% protection against the Alpha variety.
Another analysis from the public health agency in England found two doses of the Pfizer vaccine to appear to be 96% effective against hospitalization.

Peter Hotez, director of the Texas Children’s Hospital Center for Vaccine Development, told CNN New Day Tuesday that he is “deeply concerned” about the Delta’s difference, even if there is a two-dose Pfizer or Moderna’s Covid-19 vaccine that they seem to be acting “really well” to protect against it.

Now is the “crunch time,” said Hotez, who watched the surge in coronavirus cases across the South last year, with a “terrible” case of cases emerged in July and August.

“I have to believe it, in the new Delta variant, the same thing will happen again to anyone without a vaccine or just one dose of vaccine,” he said. “And it’s time for everyone to be vaccinated, because even if you want to vaccinate yourself tomorrow or your child wants to, it will still take five to six weeks to get the same dose of vaccine and a week later. “
