During this time, patients should have at least one symptomless month between the two cases. Officials at the World Health Organization (WHO) have equally stressed that the potential risk for COVID-19 reinfection is higher with Omicron than it is to other variants they've seen in years. But the two viruses that cause these infections are very, very different. In the past, experts were confident that, while reinfection is possible, the first two months after infection can keep you protected. Learn more about the other symptoms and what to expect here. And because protection wanes over time, it is crucial for people to get a booster to stay up to date, said Jha, adding that those over 50 or severely immunocompromised should get all their vaccinations right away.

"If you tested positive for COVID-19 with a viral test within the previous 90 days and subsequently recovered and remain asymptomatic, you do not need to quarantine or get tested after close contact," reads the CDC's website. It is generally thought that for vaccinated people, protection against infection drops to about 70 per cent after about six months. Professor Neil Ferguson, of Imperial College London, said: This study provides further evidence of the very substantial extent to which Omicron can evade prior immunity given by both infection or vaccination.. And scientists have already confirmed that Omicron has earned special attention at this stage of the pandemic, as evidence suggests that the strain spread more effectively than others, demonstrating an ability to reinfect someone who had previously experienced a COVID-19 illness, even sometimes within the CDC's official 90-day reinfection window. "That is to say if you had Omicron you can still get infected with BA.2," says Furness.

In short, yes. And for those who have been vaccinated and received booster shots, symptoms tend to be even less severe, or even nonexistent. A recent pre-print of a forthcoming medical study organized by researchers within the University of California system contains data that further suggests immunity earned from an Omicron infection may not be as protective as immune responses recorded during the Delta wave in 2021, let alone immunity granted by a vaccine.

Omicron, and it's sub-variant BA.2, are quicker at spreading and can get around vaccine immunity a bit better. Fortunately, as variants tend to become more infectious, they also tend to become less powerful. But due to the influx of cases and delays with genomic testing, many people won't know whether they have contracted Omicron or the earlier, and more dangerous, Delta strain. It's true that you can have COVID-19 more than once. suggesting that viral shedding or ongoing immune response may . Many factors can influence reinfection risk, such as age, geographic location, and health equity.

However, at present it is far more likely for people who were previously infected with other variants or who had not previously caught Covid at all to become infected with BA.2. The distinguishing marker of the Omicron variant is its spike protein, which contains 26 amino acid mutations. Its probable that there will be people who catch Omicron twice in the future. This article discusses current research regarding Omicron and other coronavirus variants, risk factors for reinfection, symptoms to watch for, and preventive measures people can take against reinfection. Daniel Gluckstein, MD, board certified in infectious disease, at Pomona Valley Medical Center in California, said most of the Omicron reinfections were BA.2 and researchers found lower virus levels than in prior BA.1 infections.

And a Danish preprint study found last month it is possible to have had Omicron's original strain, BA.1, and then get the sub-variant, BA.2. Scientists have found BA.2 to be between 30-50 per cent more infectious than BA.1. Researchers found only 187 cases of reinfection, with just 47 instances of BA.2 reinfection occurring shortly after BA.1 infection. This is especially true regarding omicron, currently the dominant strain in the U.S., which has 36 mutations to its spike protein. In the past, experts were confident that, while reinfection is possible, the first two months after infection can keep you protected.

Ministers noted that the data showed the importance of the booster jab, which is thought to provide protection against around 55 to 80 per cent of symptomatic cases. If you tested positive for COVID-19 with a viral test within the previous 90 days and subsequently recovered and remain asymptomatic, you do not need to quarantine or get tested after close contact, reads the CDCs website. Additionally, people are less likely to experience long COVID from this variant. However, the BA.2 variant is less likely to reinfect those who have already contracted the BA.1 variant. Cases have dropped hugely from the numbers seen in January but are still high, hovering at around 40,000 new infections a day.
