First case of infection with the Omicron strain of coronavirus detected in the U.S.
The first case of infection with the omicron strain of coronavirus has been reported in the United States. The U.S. Centers for Disease Control and Prevention said in a statement released Wednesday.
According to the health regulator, the first case of infection with the COVID-19 omicron strain has been detected in the state of California. The patient, who was found to be infected with the Omicron strain, returned to the U.S. from a trip to South Africa on Nov. 22.
The patient with the Omicron strain has been fully vaccinated against the coronavirus and is now in isolation. He is experiencing mild symptoms of the disease. U.S. President Joe Biden has previously expressed confidence that “sooner or later” the Omicron strain of coronavirus will appear in the United States.
On Nov. 26, the World Health Organization designated a variant of coronavirus B.1.1.529 found in southern Africa with the Greek letter “omicron.” The organization said in a statement that this variant of the coronavirus “has a large number of mutations, a number of which are of great concern.” Several changes in the spiking protein have the potential to make it difficult for antibodies to neutralize the pathogen, which could affect the effectiveness of vaccines. In addition, preliminary data indicate that the strain has an increased ability to spread.
