The person examined optimistic on November 29.

“The individual just lately traveled to South Africa and developed signs upon their return, and so they did the best factor and obtained examined and reported their journey historical past,” Dr. Grant Colfax, San Francisco’s director of public well being, advised reporters on Wednesday.

The individual had been absolutely vaccinated with Moderna’s COVID-19 vaccine lower than six months in the past, California’s governor mentioned on Wednesday, however was not but eligible to obtain a booster shot. 

Scientists on the College of California, San Francisco have been sequencing the overwhelming majority of optimistic assessments collected in San Francisco, and had been alerted to the potential of the doable Omicron case on Tuesday afternoon. 

“We had been capable of verify the detection of Omicron inside 5 hours and we had a lot of the genome inside eight hours. So, 4 a.m. final night time, we truly had assembled a lot of the genome. We had been capable of conclusively display that this was certainly an an infection from the Omicron variant,” mentioned Dr. Charles Chiu, professor of laboratory medication on the college.

Making ready for extra

The invention comes because the Biden administration is mulling more durable restrictions on worldwide journey, a part of a brand new technique to curb the virus that Mr. Biden plans to announce on Thursday. The CDC has additionally ramped up efforts to surveil for brand spanking new circumstances of Omicron in current days, together with an unplanned growth of a pilot program that features San Francisco’s worldwide airport.

On Wednesday forward of the announcement, the CDC ordered airways to start handing over contact data for vacationers from eight nations in Southern Africa. 

Fauci mentioned he was not conscious of some other potential Omicron circumstances being investigated by the CDC within the nation. He mentioned People ought to proceed following CDC steering to stop the unfold of the variant, and urged those that are absolutely vaccinated to “get boosted now,” saying the additional dose possible conveys some stage of safety towards the variant.

“There’s each purpose to consider that that sort of enhance that you just get with the increase could be useful not less than in stopping extreme illness of a variant like Omicron,” he mentioned. “We might not want a variant-specific increase. We’re making ready for the likelihood that we want a variant-specific increase.”

How precisely vaccines carry out towards the variant stays unclear. Although the Omicron variant shares a variety of mutations with different variants of concern that might allow it to be extra transmissible and evade the physique’s defenses, scientists have cautioned that it might take weeks to confirm in check tubes the variant’s danger. 

On “Face the Nation” on Sunday, Dr. Scott Gottlieb, a former commissioner of the Meals and Drug Administration and a member of Pfizer’s board, conveyed confidence within the vaccines.

“Individuals who have appeared carefully at this sequence … these people really feel fairly assured that three doses of vaccine goes to be protecting,” Gottlieb mentioned. “Now, that might give a very robust impetus to attempting to get extra folks boosted.”

The Omicron variant’s emergence within the U.S. comes amid the busy vacation journey season. In keeping with auto membership AAA, over 53 million People had been estimated to have traveled for the Thanksgiving vacation, a rise from final yr.

The Meals and Drug Administration says present COVID-19 assessments will possible stay correct in detecting infections by the variants, regardless of a quirk often known as “S-Gene Goal Failure” that had additionally been seen in earlier strains. A number of labs have mentioned they’re utilizing that to prioritize optimistic assessments that could be brought on by Omicron for additional genetic sequencing, to be able to confirm which variant brought on the an infection.

Public well being officers have defended the U.S. variant surveillance effort, arguing that the system of public well being and industrial labs scaled up by the CDC might detect rising variants down to 0.01% prevalence within the nation.

The CDC presently estimates that the Delta variant stays just about all circulating virus within the nation.
