The new variant has a sequence of mutations, the US Centers for Disease Control and Prevention stated.

England’s Chief Medical Officer Chris Whitty stated Saturday the brand new pressure “can spread more quickly” and was accountable for 60% of recent infections in London.

On Monday, an epidemiologist from the World Health Organization stated, “We are hearing that it could spread up to 70% faster.”

“What they’re seeing is that the reproduction number — so this is the number of individuals that an infected person transmits to — has increased from 1.1 to 1.5,” stated Maria Van Kerkhove, the WHO’s technical lead for Covid-19.

“I just want to put into context this up-to-70% increase.”

Van Kerkhove stated it’s not but clear whether or not that improve “is associated with the variant itself,” or if it’s as a consequence of human habits.

So far, “there is no evidence that this variant causes more severe illness or increased risk of death,” the CDC stated Tuesday.

But a pressure that spreads quicker might result in extra infections, which in flip would possibly result in extra hospitalizations and deaths.

Where is that this pressure now?

Outside the UK, this pressure has been detected in international locations resembling Denmark, Belgium, the Netherlands, Italy and Australia. The same however separate variant additionally has been recognized in South Africa.

As of Tuesday, the pressure “has not been identified through sequencing efforts in the United States, although viruses have only been sequenced from about 51,000 of the 17 million US cases,” the CDC stated.

“Given the small fraction of US infections that have been sequenced, the variant could already be in the United States without having been detected.”

Epidemiologist Dr. Celine Gounder stated she thinks this pressure is already within the US as a result of it’s been circulating within the UK for months earlier than this latest surge.

Public Health England stated backward tracing (utilizing genetic proof) suggests the pressure first emerged in England in September. It then circulated in very low ranges till mid-November.

“Because this virus has been circulating for some period of time in the UK already, the cat’s out of the bag,” Gounder stated. “It has spread elsewhere, including the United States.”

Who’s getting contaminated essentially the most with this pressure?

“Most COVID-19 cases from whom this variant has been identified have occurred in people under 60 years of age,” the World Health Organization stated Tuesday.

That will be problematic as a result of “when people are asymptomatic, they usually are under age 60,” CNN Senior Medical Correspondent Elizabeth Cohen stated.

“So that may be why this is spreading so quickly — or part of the reason — is that many of these people aren’t showing symptoms, so they’re running around and spreading it.”

While extreme sickness from Covid-19 is comparatively uncommon in youngsters, “there is a hint is that [the new strain] … has a higher propensity to infect children,” stated scientist Neil Ferguson, a member of the UK’s New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG),

But he stated extra information is required.

This new pressure means “we have to work a little bit harder about preventing the spread,” Van Kerkhove stated.

Gounder agreed. “What we really need to be doing is focusing on the things we know will prevent spread of this new variant — which is the same thing that works against spread of the coronavirus in general,” she stated.

“That is masks, social distancing.”

Will vaccines work towards this new pressure?

Both the Pfizer/BioNTech vaccine and the Moderna vaccine have proven efficacy charges of round 95% in medical trials. But now many marvel if the vaccines would work on variant strains on the virus — just like the one spreading quickly within the UK.

Pfizer and Moderna stated they’re testing their vaccines to see in the event that they work towards the UK-based pressure.

The new pressure might mean extra individuals might want to get vaccinated to realize herd immunity, BioNTech CEO Ugur Sahin stated Tuesday.

“On the topic of herd immunity, there is always the discussion about 60% to 70%,” Sahin stated.

“But if the virus becomes more efficient in infecting people, we might need even a high vaccination rate to ensure that normal life can continue without interruption.”

The novel coronavirus has mutated earlier than, and each vaccines have labored towards variations of the virus.

When can YOU get the vaccine?

“Up to now, I don’t think there has been a single variant that would be resistant to the vaccine,” Moncef Slaoui, chief science adviser for Operation Warp Speed, stated Sunday.

“We can’t exclude it, but it’s not there now.”

Scientists on the Walter Reed Army Institute of Research are inspecting the variant and anticipate to know within the subsequent few days whether or not vaccines won’t work towards it.

How does this pressure impression journey?

At least 24 international locations at the moment are banning passenger journey from the UK, together with Canada, Russia, Chile, Italy, Iran and Sweden.

So far there aren’t any plans for the US to enact a journey ban towards the UK, US Assistant Secretary for Health Adm. Brett Giroir stated Monday.

British Airways, Delta Airlines and Virgin Atlantic have agreed to require passengers get examined for Covid-19 earlier than boarding planes from the UK to New York, Gov. Andrew Cuomo stated.

But some well being specialists say Americans should not be touring anyway as a result of new Covid-19 hospitalizations and deaths are hovering — and it’s simple to contaminate family members with out realizing it.

“This is really not the time to be traveling,” Gounder stated.
