What are the Omicron symptoms? Everything we know


Today, the World Health Organization (WHO) has urged people to cancel some holiday plans to protect public health, as the Omicron strain of the Coronavirus continues to spread across the globe. “An event canceled is better than a life canceled,” said WHO head Dr. Tedros Adhanom Ghebreyesus.

In the US, Omicron accounts for 73% of new infections, and President Joe Biden is expected to address the nation on Tuesday. Omicron is also the most dominant variant in the UK, which is estimated to be doubling every 2.4 days in the southwest of the country. But what are the symptoms of infection with the Omicron variant, and how is it different?

Health officials say it is currently too soon to tell whether the disease is milder with the Omicron variant, first detected in South Africa in November. However, here’s what we know so far:

What are the symptoms of infection with the Omicron variant?

The most commonly reported symptoms of infection with Omicron are a lot more cold-like than other variants of Coronavirus. In the US and UK, those infected have reported having a:

  • Runny nose
  • Headache
  • Fatigue (either mild or severe)
  • Sneezing
  • Sore throat

In the UK, Tim Spector, the lead scientist behind the Zoe Covid Study app, has been calling the Government to update the list of Coronavirus symptoms, which has remained unchanged since the Delta variant. “We need to educate people, go back to the basics, and say that if you’ve got cold-like symptoms keep away from people. You shouldn’t be waiting for the three classic symptoms,” he said.

What do we know about the Omicron variant?

The CDC has confirmed that it’s still too soon to answer a lot of questions about the Omicron variant — “we don’t yet know how easily it spreads, the severity of illness it causes, or how well available vaccines and medications work. Against it.”

However, we know that the Omicron variant has more than 30 mutations to the virus’ spike proteins. These proteins cover the outside of the virus and are the main targets of vaccines. Throughout the pandemic, there have already been several virus mutations, including the Delta variant. While most mutations won’t affect how the virus operates, a few are thought to make Coronavrius more transmissible, and that is the concern with Omicron.

Is Omicron more contagious than other variants?

The CDC says Omicron is likely more contagious: “The Omicron variant likely will spread more easily than the original SARS-CoV-2 virus and how easily Omicron spreads compared to Delta remains unknown. CDC expects that anyone with Omicron infection can spread the virus to others, even if they are vaccinated or don’t have symptoms.”

As reported by USA Today, the omicron variant multiplies 70 times faster in the human bronchial tubes than the initial COVID-19 infection or the delta variant. This is according to a new study from the University of Hong Kong.

At the moment, more research is needed before conclusions can be made. However, according to the CDC, vaccines and face masks are the best protection. Here’s everything you need to know about where to buy rapid Covid test kits and where to buy the best face masks online.

Do current vaccines work on the Omicron variant?

An analysis released on December 14 by South Africa’s largest health care administrator found that two shots of the Pfizer-BioNTech vaccine were 70 percent effective at protecting against hospitalization from the Omicron variant. However, this is less than the 90 percent protection against hospitalization the vaccine offered from the Delta variant. As a result, vaccine creators have said a third shot was the best way to neutralize the Omicron variant.

Researchers at the Imperial College London also found that Omicron largely evades immunity from two vaccine doses or past infection. In addition, researchers found the risk of reinfection with the Omicron variant 5.4 times greater than that of the Delta variant. According to a press release,

Pfizer has reported that those who took the initial two-dose series were still vulnerable to being infected by Omicron. But a third booster dose of the Pfizer vaccine “increased the neutralizing antibody titers by 25-fold” that we’re able to fight the omicron variant.

As reported by the Associated Press, Moderna has announced that its COVID-19 booster should offer protection against the omicron variant based on initial lab tests. In addition, Moderna says that its half-dose booster shot increased the neutralizing antibody titers by 37-fold.

This is a rapidly changing situation, and for up-to-date Coronavirus advice, consult the World Health Organisation, the CDC in the US, and the NHS in the UK.
