For probably the most up-to-date information and details about the coronavirus pandemic, go to the WHO and CDC web sites.

Now in at the very least 36 states, the omicron variant makes up 3% % of circumstances within the US, Dr. Rochelle P. Walensky, director of the Centers for Disease Control and Prevention, said during a White House briefing on Wednesday. (The delta variant acounts for 96% of COVID nfections.)

Scientists are piecing collectively an image of how simply the virus can move from one individual to a different and evade safety offered by the first vaccine doses of Pfizer, Moderna and Johnson & Johnson. Looking on the newest information, Dr. Anthony Fauci, chief medical adviser to President Joe Biden, said on Wednesday omicron can bypass a lot of the safety given by two photographs of the mRNA Moderna and Pfizer vaccines. “The omicron variant undoubtably compromised the effects of a two-dose mRNA vaccine-induced antibodies and reduces the overall protection.” More promising, Fauci unhappy,boosters seem to revive protections ranges wanted to protect towards the brand new variant.

In the US, President Joe Biden is doubling down on urging vaccines and booster shots till extra data on the brand new variant turns into accessible. As a consequence, the US administered 12.5 million shots in the last week, in keeping with Jeff Zients, the White House coronavirus response coordinator. That’s the very best variety of weekly photographs since May. Seven million of these have been booster photographs, Zients mentioned.

So far, the COVID-19 vaccines have confirmed to be highly effective in stopping hospitalization and dying, with people who find themselves unvaccinated being greater than 10 times more likely to be hospitalized if contaminated. Vaccine makers are optimistic the present vaccines licensed to be used within the US will present a level of safety towards omicron, too.

Here are eight necessary issues to find out about omicron at this time. For extra on COVID-19 boosters, here is a trick to simply get an appointment and a free ride. Here’s how you will quickly get a COVID-19 test kit for free and particulars on mixing and matching vaccines.

A COVID vaccine booster is needed to guard against omicron

Early studies indict a booster can guard againt omicron. “Boosters … enhance the vaccine protection against omicron,” Fauci said on Wednesday. “Our booster vaccine regimens work against omicron.”

“Individuals who have received two vaccines will most likely not have significant prevention from infection or any type of disease [from the new variant],” BioNTech CEO Uğur Şahin mentioned final week. Şahin mentioned extra data is required to verify the corporate’s preliminary laboratory findings that point out a 3rd Pfizer vaccine dose is necessary to protect towards the variant.

Is an omicron-specific vaccine wanted?

Pfizer/BioNTech, Moderna and Johnson & Johnson say they’re gearing as much as create a vaccine designed to fight omicron if wanted.

Fauci on Wednesday mentioned a this level, there is no such thing as a want for a variant-specific booster. The present booster seem like efficient towards omicron

So far, the omicron virus is creating gentle signs

According to Fauci, preliminary data appears to point omicron could produce much less severe signs than initially feared: “We’re getting anecdotal information … that the level of severity appears to be maybe a bit less than in the delta,” he mentioned Sunday.

The new COVID variant could unfold extra simply than delta

It may nonetheless be two or three weeks until we all know extra about how simply omicron will be handed between folks and the way resistant the mutated virus is towards the present crop of vaccines, however Fauci on Tuesday at a White House briefing mentioned that early information additionally suggests omicron could be more infectious than the delta variant and is changing delta because the dominant COVID-19 pressure in South Africa.

Omicron confirmed in 36 US states

It makes up 3% of the circumstances within the US. In New York and New Jersey, nonetheless, it could possibly be 13% of recent infections.

The variant has been detected in 36 states throughout the nation, from Washington to Mississippi and Texas to Utah. The US and different international locations have been already bracing for an elevated caseload as colder climate and vacation gatherings introduced extra folks indoors collectively. Now, projections of a winter surge of the dominant delta variant be part of issues about omicron’s unfold.

Add to that increasing flu infections, and consultants fear a couple of “twindemic” of the two illnesses.

Omicron may turn into the dominant COVID variant in Europe in months

In Europe, omicron may turn into the commonest COVID-19 variant in months, in keeping with the European Centre for Disease Prevention and Control.

“Mathematical modeling indicates that the Omicron VOC is expected to cause over half of all SARS-CoV-2 infections in the EU/EEA within the next few months” resulting from early understandings of the omicron variant’s excessive transmissibility between folks, the physique mentioned in a Dec. 2 briefing (PDF). 

Scientists finding out the omicron variant in South Africa, the place it was first reported to the World Health Organization, have mentioned it is spreading more than twice as fast as the delta variant. But what is not but recognized is whether or not the unfold is hastened as a result of the mutations make it simpler to unfold amongst folks, if vaccines are much less efficient towards this pressure or for another motive. The study cited by The New York Times has not but been printed or peer-reviewed.

Omicron is similar to the delta variant’s mutation

COVID latches onto cells utilizing a spike protein in its construction. Omicron has more mutations than the delta variant, which is taken into account at the very least twice as contagious as previous strains. While it is not clear but if omicron is kind of contagious than delta, the presence of these mutations is one reason for concern. 

That could also be one motive international locations world wide have banned travel from some countries in southern Africa and increased travel restrictions that embody a unfavorable COVID-19 take a look at 24 hours earlier than journey, no matter vaccination standing.

Drugmakers are exploring if the present vaccines are efficient towards the brand new variant.

COVID PCR assessments can establish the omicron variant

Most PCR assessments to establish the presence of COVID-19 within the physique are free (COVID-19 assessments for worldwide journey are the primary exception). So it is excellent news that the prevailing nasal swab take a look at has been discovered to detect the omicron variant; a blood take a look at or different process up to now is pointless.

“Fortunately for us, the PCRs that we mostly use would pick up this very unusual variant that has a real large constellation of mutations,” Fauci mentioned Nov. 29 in a press briefing.

Booster photographs and vaccines are urged to assist forestall omicron’s unfold

On Dec. 2, Biden introduced a plan to help protect the US against the omicron variant this winter. It consists of:

  • Outreach packages to contact folks eligible to obtain booster photographs.
  • Making at-home COVID-19 tests “free” for everyone.
  • Tighter journey restrictions that require a unfavorable COVID-19 take a look at 24 hours earlier than departure.
  • Paid day without work for federal staff to get booster photographs.
  • Securing antiviral pills as a treatment for individuals who turn into contaminated with COVID-19 (these are really helpful however not but FDA-approved).
  • Sending 200 million extra doses of COVID-19 vaccine to worldwide international locations within the subsequent 100 days (280 million have already been despatched).
