Even though its not known exactly how effective vaccination will be against omicron, it almost certainly will provide some protection, and of course will help against delta, which is still thedominant variantin the U.S. The vaccines are so efficient and they work so great, there is so far no indication that they would not at least partially protect you against this new variant, said the University of Berns Thiel. Someanecdotal reports from physicians in South Africa have indicated that perhaps omicron could be less pathogenic than other variants, as many of the illnesses appear to be mild or without symptoms. Researchers found that when using only a throat sample, the tests missed half of positive cases. However, infections in the US are going up dramatically from delta. We really cant say anything about severity of disease at the moment, he said. If you did get sick, that waiting period will give the virus enough time . That means many Americans who have . There is some evidence to suggest that people who have had COVID-19 and also have been vaccinated might do better. In the lab, scientistswill testwhether and at what concentration sera from vaccinated people and from convalescent patients can neutralize omicron or a mock virus with a similar set of mutations.

If the findings support it, an authorization could come quickly, Woodcock said. how long does it take for Omicron positive to turn negative.

Other parts of the immune system, such as T cells, he said, should be much less affected.. Experts say the limited data are hard to parse, and there are several factors other than a change in disease severity that could explain the observations.

Prior to the latest rise in cases, South Africa hadrelatively little coronavirus transmission, also making it difficult to say whether omicron can necessarily outcompete delta, either because of increased transmissibility or immune evasion. Before advocating the altered approach, Li said, he would need to see data that showed it was effective. How long after an exposure does it take to test positive?

Im not saying it wont turn out that you can use throat swabs, we just dont know the impact that it has yet on the test results, she said. So just seeing the S gene dropout doesnt mean youre seeing omicron. For this reason, she said its important for people to sequence the viruses that do show S gene dropout to confirm that it is omicron. The Centers for Disease Control and Prevention recently shortened its isolation guideline s, citing evidence that COVID is most contagious 1 to 2 days before someone starts feeling symptoms and 2 to 3 days after. The agency has limited the use of certain monoclonal antibodies based on variants before. I expect a substantial drop in protection against overall infections and mild disease, but less of a drop against severe disease,. During the earlier and final days of infection, it will show up lighter, and darker when the infection is at its height. Based on this information, scientists have put forward three main hypotheses for how omicron originated. It will take longer to gather data on the real-world experience of vaccinated people. The WHO gave the variant its Greek alphabet name on Nov. 26 and labeled it a variant of concern, meaning it could be associated with an increase in transmissibility or virulence, or a decrease in effectiveness of vaccines. . Watching what omicron does in other places will provide a clue as to whats going on, Althaus said in a Nov. 30. hosted by the Swiss National Science Foundation.

In a couple of weeks, it should become more clear how impotent peoples neutralizing antibodies are against the variant. My recommendation would be all of the FDA guidance on this, but also we have to follow the science.. In fact, sequencing data suggests the viral lineage goes way back, possibly to mid-2020. I ran a quick search, and it seems we can continue to test positive for weeks and sometimes months after being infected, but we aren't likely to be contagious the entire time. Mutations present in the variant are predicted to dramatically. Lateral flow tests might not pick up Omicron in the first few days of infection, an expert has suggested. Omicroncontainsnumerous mutations in its spike gene that are predicted to make neutralizing antibodies less effective, suggesting the variant could have an easier time reinfecting people who have recovered from COVID-19 and infecting vaccinated people. Thats the norm.. The incubation period for COVID is said to be two to 14 days, with an individual considered infectious starting two days before they develop symptoms or two days before the date of their positive test, if they do not have symptoms.

Wherry, the University of Pennsylvania immunologist, said that for the other variants, both are protective, but vaccination immunity is typically more consistent at the antibody level, while there may be broader T cell responses after infection..
