This variation, first identified in India, continues to spread around the world, and has led to the reintroduction of health restrictions in many countries.
The same number was up from 9 to 10% last week, according to a report released Tuesday by Health Minister Oliver Veron that the delta variant represents “about 20% of new diagnoses” in Covit-19 cases in France. The alarming increase, especially in the United Kingdom, as in other countries, the rapid progress of this mutation led to the re-establishment of controls.
Although braking operations in France have been phased out in recent weeks, fears of a recurrence of the epidemic in delta circulation are likely to re-emerge in the fall.
Where does the delta variant come from?
Originally titled “Indian Variation”, it was “first detected in India in October 2020”, Public Health France Explains, Gradually, but rapidly, spreading around the world.
This variant is divided into three sublines: B.1.617.1, B.1.617.2, B.1.617.3. This means that it differs slightly in terms of mutations, and in these three versions, it is P.1.617.2 (Also known as 21A / 478K) This is by far the most mentioned.
Where is he?
According to the latest WHO update, June 22nd, The delta variant is found in at least 85 countries around the world, on all continents. It said it had “consistently reported new countries in all WHO regions, including 11 in the past two weeks.”
In France, several clusters of delta variants have been identified, especially in the Landes, where the government says the situation is under control. The variant is dropping “including Landus at the moment”, thus being promised to Oliver Warren on Tuesday. France Information.
In this area, the government has a “very strong action plan.” Communication tracking (Look for contact cases, author’s note), Mass vaccination and incidence rate drops by 10% in a few days “.
Cases have been found in Hot-Savoy, Strasbourg (Boss-Rin), but also in the Antilles or Reunion.
More Is it more contagious?
According to British data, the delta is 60% more contagious than the alpha variant (formerly the English variant). In particular this uniqueness led to the transformation of the alpha variation across the channel between pollutants.
A mutation in this variant was recently identified, nicknamed Delta Plus. It’s about a few cases so far, but the virus is still contagious. According to a report by Indian health officials Last week.
However, although this variant has not been proven to be very dangerous, the virus is highly contagious and thus affects a large part of the population, automatically admitting itself to more viable hospitals.
More Is it too dangerous?
This question is still difficult to answer, especially due to the lack of data. Inheritance B.1.617.2 VOC – Variations of Concern – By whom, Or mutations should be carefully monitored as they may pose a risk to public health.
“Early evidence from the UK and Scotland suggests that people with delta disease are twice as likely to end up in hospital as people with alpha disease,” says the journal. Natural. But this latest data needs to be integrated.
As for the Delta Plus, it will be more severe, according to Indian officials, but for the WHO announced last week that “for now, this variation does not seem to be common, and currently represents only a small part of the Delta views” ReutersHowever, the delta variant “and other VOCs pose a greater risk to public health because they have proven to have an increase in the spread of the virus”.
Are Vacc Vaccines Effective?
Faced with this variation, the effectiveness of vaccines is questionable. According to current data, compared to the alpha variant, the estrogen and Pfizer vaccines are less effective against infection, but more effective against symptomatic forms.
A study by British health officials Pfizer explains in mid-June that Pfizer is 96% effective against hospitalization after two doses and 92% more effective for AstraZeneca after two doses. However, safety is lower after a single dose (approximately 30%). In this sense, it is important to have both injections to protect against severe symptom forms.
Little information is currently available about the products of Moderna and Jansen.
What should Spread do to control its spread?
Current variation gestures are useful for protecting and screening from this variation. According to the plans of the Institute Pastor for the Fall, Weekly tests performed on at least 50% of people over the age of 12 can reduce hospital admissions by 27% by self-examination and by 32% “if the test is performed by a specialist”.
At Lands, thousands of self-tests have been distributed to control the rotation of this variant, and target screenings have been arranged.
The most effective solution currently known is the vaccine. In the UK, more than 60,000 cases of delta variation have been identified, Only 4000 people (6.7%) had a complete vaccination schedule and 35,000 people were not vaccinated. The Institute Pastor also recalls the important parameter of the vaccine in the current health situation: “Unknown people make a proportionate contribution to the spread: 12 times more likely to spread SARS-CoV-2 than a person who has been vaccinated”.
As the vaccination campaign has slowed in recent days, Oliver Warren has recalled that “people are not vaccinated, especially those who are susceptible to infection variation,” and encouraged people to get vaccinated.
