Is it possible to get Omicron twice? The Omicron variant spreads easier than other variants of coronavirus, and people can get it twice. Reinfection is possible even if a person has already had this virus or is fully vaccinated.
This is why it's so important to get your bivalent booster to further protect yourself against the Omicron variants! The majority of reinfections occur at least 90 days after the initial COVID-19 infection.
Data from long-term studies showed that protection against reinfection for pre-omicron variants dropped to 78.6% over 40 weeks, whereas for omicron BA. 1 it dropped more rapidly to 36.1%. When assessing severe disease, however, all variants showed sustained protection above 88% for 40 weeks.
The effectiveness of previous pre-omicron infection, followed by BA. 1 or BA. 2 infection, against BA. 2.75 reinfection was 56.4% (95% CI, 50.5 to 61.6).
In addition, the findings indicated that when the predominant variant infection was almost equal among the Delta and Omicron VOCs, reinfections were attributed to Delta in 0.6% and Omicron in 1.6% of cases.

As the virus evolves, new variants with the ability to evade your existing immunity can appear. This can increase your risk of reinfection. Reinfection can occur as early as several weeks after a previous infection, although this is rare.
The answer boils down to one key factor: Their mutations allow them to re-infect people who have already had an omicron infection. This reinfection risk may be higher for people who are not vaccinated. In the studies, researchers took blood from people infected with the original omicron variant, BA.
Already had COVID? You can still get infected with the omicron variant.
The researchers found that people who got sick with any pre-Omicron version of the coronavirus, though, had substantially reduced protection against infection from the BA. 1 subvariant of Omicron: only 36% at 10 months after infection.
In high-risk settings, they may be considered infectious from 72 hours before symptoms start. People with mild illness are generally considered recovered after 7 days if they have been asymptomatic or have not developed any new symptoms during this time. But some people may be infectious for up to 10 days.
You can be reinfected even if you've also been vaccinated and boosted—that is, “super immunity” against infection is no longer so super.
If you experience rebound symptoms, you are likely contagious again. You should isolate yourself to prevent passing the disease to others. For more information, consult your doctor or the CDC guidelines.
Some people can test positive for COVID-19 for weeks or even months on PCR tests, but there is good news: people are not likely to be contagious for that long from a single infection, even if they test positive, and therefore are unlikely to transmit the virus to others.
Can you get Covid-19 twice? Yes, it is possible to get Covid-19 two, three or even more times. Covid reinfections have become more common because of the Omicron variant, and because immunity from previous infection and immunisation has reduced over time.
How soon could I get COVID-19 again after already having it? Immunity is highest in the following weeks after infection. After a few months, those antibodies will go down. With the emergence of new variants, it is possible to be infected again, so it's best to take precautions to protect yourself from reinfection.
COVID-19 rebound is when people with COVID-19 get better, then begin to get symptoms 2-8 days after they have recovered. They may also test positive again. COVID-19 rebound is seen in people who received treatment for COVID-19 as well as in people who did not receive treatment.
People with no symptoms can also spread the coronavirus to others. By the 10th day after COVID symptoms begin, most people will no longer be contagious, as long as their symptoms have continued to improve and their fever has resolved.
A negative result from a COVID-19 rapid test is usually enough to ease worries, but one test isn't enough to rule it out. One negative result could mean that you don't have a contagious amount of the virus at the time of testing, even if you do have COVID-19 already, Adalja said.
The original Omicron strain (BA. 1) was first identified in Botswana and South Africa in late November 2021, and cases quickly began to surface and multiply in other countries.
There have been some cases of second infections reported. Even if you have had mpox in the past, you should be doing everything you can to avoid getting re-infected.
People with Long COVID can have a wide range of symptoms that can last weeks, months, or even years after infection. Sometimes the symptoms can even go away and come back again.
