However, many countries recommend against retesting. Research has shown that for people who recover from Covid-19, immunity can last for a period of about three months to several years, making it very unlikely someone could catch the virus twice. Emerging research suggests that omicron multiplies remarkably rapidly in the body, possibly 70 times faster in the lungs, compared to the delta variant, for instance. This report describes 10 patients from four states, with whole genome sequencing (WGS)-confirmed Omicron variant infections within 90 days of a previous Delta infection. Research has shown Omicron is better at getting past defences built up by previous variants. Unvaccinated people were at high risk of contracting the Delta variant. 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. This evolution makes COVID-19 similar to other viruses weve seen. News, Discovery, and Analysis from Around the World. The latest data, as shared in a recent report published by Aljazeera, suggests that reinfections accounted for 10% of newly confirmed cases in the U.K. in January and in Italy, 3%, which was double what it was prior to Omicron's spread in the nation. 2004-2023 Healthline Media UK Ltd, Brighton, UK, a Red Ventures Company.

More than one positive test for any variant of Covid-19 within a 90-day time period is considered to be part of the same case episode, and if you test positive a matter of weeks after first getting a positive test, it is more likely this is from the residual effects of the initial infection. While data is still limited around Omicron spread given that researchers need more time to confirm trends, real-world data of Omicron spread in South Africa suggests that overall immunity may be less robust following a mild COVID-19 infection, which has been the case for most Omicron sicknesses, says Sanjiv S. Shah, M.D., chief medical officer for MetroPlusHealth. But experts say you are much less likely to be unwell the next time you catch Covid compared to previously. One 2022 study states that the Omicron variant appears to cause less severe symptoms and have a shorter duration than previous variants. Prof Alex Dornburg, assistant professor of bioinformatics and genomics at the University of North Carolina at Charlotte, said: As new variants arise, previous immune responses become less effective at combating the virus. What Happens After the Omicron Wave Passes? Amiji adds that as vaccines continue to aid an ever-expanding amount of the population in blocking potential viral infections, it makes sense that SARS-CoV-2 strains will likely continue to mutate in response. With BA.5, that is changing. Can you get omicron twice? The strain was first identified back in November 2021, the same time as BA.1. Related: Your child has COVIDnow what?

Experts say Omicron likely wont result in a surge of severe illness, but we need to maintain our guard against new COVID-19 variants. This reinforces the importance of getting vaccinated and boosted. Symptoms of COVID-19 due to the Omicron variant are so similar to those of other coronavirus variants that it makes the Omicron variant more difficult for healthcare professionals to detect through symptom-based testing or PCR testing alone. Dr Amesh Adalja, senior scholar at Johns Hopkins Centre for Health Security in the US, said: Its unclear, at this point, what level of immunity occurs after an Omicron infection. For the unvaccinated, a study by the Yale School of Public Health found their immunity from a prior infection could be anywhere between three and 61 months. Probiotic supplements can be used as one part of an immune-boosting protocol to help reduce the likelihood of coronavirus infection.

Additionally, the BA.2.75, an omicron subvariant with many mutations, is expected to be the next variant casing a wave, according to inewsource. Under pressure from natural immunity and other countermeasures to its survival, the COVID-19 virus mutates these spike proteins at random, creating new variants that are more transmissible than previous ones. For those with Pfizer or Moderna, the effectiveness is just ten per cent. Are pulse oximeters less accurate for people of color?
