What is Delta variant coronavirus?

The coronavirus is constantly evolving, creating many variations, a source of concern for the scientific community. After the Alpha particular variant and the Delta variant, the two most popular, a new variant has only been identified in India. This is a variant … of the Delta variant itself. More precisely, the mutation was found in residual 417 of the S protein where a lysine gave way to an asparagine, Futura Science informed us.

This Delta Plus variant has been seen in the states of Kerala, Mahashrata and Madhya Pradesh. So far, Indian health authorities do not know whether this variant is more contagious, more deadly, more dangerous or not. Undoubtedly, India classified this variant as “a different concern”.

An increase in cases translates into more hospitalizations, which further burden healthcare workers and health systems, while putting them at greater risk of death, the WHO chief said.

He admitted that new variants are expected, saying “that they are viruses, they are evolving” and stressed that we can eradicate the emergence of variants by transmitting the transmission.

“It’s very simple: more transmission, more variations.” Less transmission, fewer variants, “explains Tedros, noting that today it is even more urgent to prevent transmission by using consistent public and social health measures with vaccines.

“This is why the WHO has been saying for at least a year that vaccines should be distributed fairly to protect the vulnerable and vulnerable,” he said.

Maria Van Kerkhove, WHO’s Technical Director at COVID-19, said: “The world situation is very fragile” and “countries need to be careful.”

Considering that Delta has “proved extremely contagious in all the countries it reaches,” he warned that it is transmitted among unvaccinated people, “even in countries with high immunization rates.

Is the Delta variant more deadly?

There is still no data on whether the delta variant causes more deaths.

In the UK from 1 February. Until June 7. There were 42 deaths due to the delta variant. Among them, 23 people were not vaccinated, seven died more than 21 days after the first dose of the vaccine, and 12 died more than two weeks after the second. dose.

According to PHE, compared to the alpha variant, the delta variant is more likely to cause hospitalization.

On June 7-13, more than 1,300 people were admitted to hospital for all COVID-19 variants, or 43 percent. More than last week.

Pfizer-BioNTech and AstraZeneca vaccines are slightly less effective in preventing hospitalization in people with the delta variant than with the alpha variant.

According to the PHE preprint, the Pfizer-BioNTech vaccine is 6% less effective for the delta variant and AstraZeneca is 1% less effective.

“Data from the UK tells us that he is more likely to be hospitalized, so it’s no surprise if it turns out to be more deadly,” Gurdasani said.

Although more work is needed to determine the level of protection against death in the delta variant, the PHE said it should be high.

“While vaccinations can be avoided in countries where they are widely available, this link between cases and hospitalizations will still not be lost,” Gurdasani said, “and we know that there is still a large vulnerable population in much of the world who has not yet been vaccinated. ”

More information is needed to confirm the studies and report that the delta variant causes a more serious disease, said WHO COVID technical officer Maria Van Kerkhove.

“We need more information to determine: is it really the option itself, or is it a combination of factors?
