Today, the World Health Organization (WHO) called for the cancellation of holiday plans to protect public health as the Omicron strain of coronavirus continues to spread globallyDr Tedros Adhanom Ghebreyesus, head of WHO, said, "Canceling an event is is better than having one's life cancelled," he said [In the US, the omicron form accounts for 73% of new infections, and President Joe Biden is scheduled to address the nation on Tuesday Omicron is also the most predominant variant in the United Kingdom, estimated to be doubling every 24 days in the country's southwest But what are the symptoms of infection with the Omicron form and how do they differ?

Health officials say it is too early to determine whether infections caused by the omicron variant, which was first detected in South Africa in November, are mild Here is what we know now:

Cold-like symptoms are most commonly reported in cases of infection with omicron, more so than with other variants of coronaviruses In the United States and the United Kingdom, infected individuals report the following symptoms:

In the United Kingdom, Tim Spector, the lead scientist for the Zoe Covid Study app, has called on the government to update the list of coronavirus symptoms He said, "We need to educate people, get back to basics, stay away from people if they have cold-like symptoms, don't wait for the three typical symptoms"

The CDC has confirmed that it is still too early to answer many questions about the omicron variant

However, it is known that the omicron variant has more than 30 mutations in the virus' spike proteins These proteins cover the outer layer of the virus and are the primary targets of vaccines During the course of the pandemic, there were already many mutations in the virus, including the delta variant Most of the mutations do not affect the activity of the virus, but some are believed to make coronaviruses more infectious, which is a concern with Omicron [Omicron is more transmissible than the original SARS-CoV-2 virus, and it is not known how much more transmissible it is compared to Delta; the CDC expects that people infected with Omicron could spread the virus to others, even if they are vaccinated and have no symptoms They state

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

At this point, more research is needed before conclusions can be drawn; according to the CDC, vaccines and face masks are the best preventive measures; according to the CDC, vaccines and face masks are the most effective; according to the CDC, vaccines and face masks are the best preventive measures

Two doses of the Pfizer-Biontec vaccine were 70 percent effective in preventing hospitalizations due to the omicron variant, according to an analysis released on December 14 by South Africa's largest healthcare management organization This is lower than the 90 percent preventive effect against hospitalization due to the delta variant Vaccine developers have stated that a third dose is optimal to neutralize the omicron variant

Researchers at Imperial College London also found that omicrons largely evade immunity from two vaccinations or previous infection The researchers found that the risk of reinfection for the omicron variant was 54 times that of the delta variant

Pfizer reported in a press release that those who received the first two vaccinations are still susceptible to Omicron However, a third booster dose of Pfizer's vaccine resulted in a "25-fold increase" in neutralizing antibody titers capable of fighting omicron mutagens

As reported by the Associated Press, Moderna announced that the COVID-19 booster should provide protection against omicron mutants based on initial lab tests; Moderna said that a half-dose booster injection increased neutralizing antibody titer 37-fold The company said that a half-dose booster injection increased neutralizing antibody titers 37-fold [For the latest coronavirus advice, see the World Health Organization (WHO), the CDC in the US, and the NHS in the UK
