The Omicron variant was first reported in southern Africa last week, though it was likely already present in multiple other countries and it’s unclear where it originated. The new variant, which the WHO has declared a “variant of concern” has a high number of mutations that might make it more transmissible, similar to the Delta variant, which accounts for nearly all of the COVID-19 cases in the US currently. Definite knowledge of the transmission of Omicron will take some time to understand, including whether current vaccines are less effective against it. At this time, though, Dr. Fauci recommends everyone who is eligible for a booster shot to receive one, as it will reduce the risk of contracting any COVID-19 variant and reduce severity of breakthrough cases. To protect against the spread of all variants, it is important to get vaccinated, receive booster shots if eligible, and continue receiving COVID-19 tests when possible. The US has restricted travel from South Africa and seven other countries as of Monday out of an “abundance of caution,” although permanent US residents and citizens can still return to the country. Scientists caution that it is not clear if this variant is any more dangerous than other versions of the virus, but it is a new concern that does need to be taken seriously. The World Health Organization has said that the global risk for the spread of Omicron is high, and although many are operating like the world is done with COVID-19, the virus is not done with us.
