Covid-19 in the UK: Delta subvariant put under health surveillance

Published on: 10/22/2021 – 7:44 PM

While the United Kingdom registers a resurgence of the epidemic, the country’s health authorities announced this Friday that they had placed the subvariant Delta, considered more contagious, under surveillance.

British health authorities said on Friday, October 22, that they had placed under surveillance the spread of the subvariant Delta in the UK, which appears more transmissible but not more dangerous, in a context of increasing cases of Covid-19.

The “AY4.2” variant accounted for 6% of all cases in the UK last week, the UK Health Security Agency said in its weekly bulletin, which classified it as a “variant under investigation”.

Therefore, it does not represent a “worrying variant” in its current form.

“Preliminary evidence appears to prove that it has a higher transmission rate compared to the Delta,” the British public health agency said.

Leap of the epidemic

“More evidence is needed to determine if this is related to a change in the behavior of the virus or to epidemiological conditions,” he added.

On the other hand, this variant “does not seem to cause a more serious version of the disease or make the vaccines currently distributed less effective,” he stressed.

This variant is cause for concern as the UK suffers from one of the worst pollution levels in the world.

After registering more than 50,000 cases on Thursday for the first time in three months, it registered 49,298 cases and 180 deaths on Friday, bringing the total balance of the pandemic to 139,326 deaths in the country.

No return restrictions

Despite increasingly urgent calls from the medical world, Prime Minister Boris Johnson is refusing to reinstate certain restrictions, such as indoor masks, after lifting the latest restrictions in July.

However, the head of government considered that on Friday it was “sensible” to wear the mask indoors, while recalling that the government’s priority was to convince those over 50 to receive a third dose, while the campaign of withdrawal is still slow.

Some scientists attribute the current wave to the absence of restrictions, to the decline in immunity of the most vulnerable vaccinated very early in the UK, but also to poor vaccination of adolescents.

According to the latest weekly study by the Office for National Statistics, infection rates are highest among children in England, with nearly 8% of secondary school students (11-16 years old) infected in mid-October and on 3, 8% among children from 2 to 11 years old. compared to 1.79% of the entire population.

This gives hope of an appeasement during the school holidays next week.
