At least 15 states have discovered the variant of Omicron coronavirus, and that number is expected to increase, said Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, told ABC News on Sunday.
“We know we have several dozen cases and we’re following them closely. And we’re hearing more and more likely cases every day, so the number is likely to rise, ”Walensky said in“ This Week ”.
The variant first discovered in South Africa has several mutations in the spike protein that allow the virus to enter the body, and some of these mutations could lead to increased antibody resistance and transmission. Scientists are still collecting data on the virus and the effectiveness of current Covid-19 vaccines.
After being discovered in several other countries, the US reported its first Omicron case on December 1. While some patients had recently traveled to southern Africa, others had no travel history. This indicates that the communion transmission is ongoing.
To prevent the virus from spreading in the US, officials initially restricted travel to non-US citizens from South Africa, Botswana, Zimbabwe, Namibia, Lesotho, Eswatini, Mozambique and Malawi.
Dr. Anthony Fauci, the leading US infectious disease official, told CNN’s State of the Union on Sunday that he hoped the ban could be lifted in a “reasonable time”.
However, the vast majority of cases in the US are still caused by the Delta variant.
“We currently have about 90 to 100,000 cases per day in the United States, and 99.9% of those are delta,” Walensky said.
