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. To help stop the spread, Amiji recommends getting tested if you have symptoms, and if a rapid testwhich is less sensitive than a PCR testis positive, you should isolate and wear a mask indoors. But reinfection caused by Omicron specifically for those who became sick by its initial spread isn't as concerning or rampant as confirmed second cases of COVID-19 for individuals who were previously impacted in early 2021 and 2022, fueled by new Omicron spread, Aljazeera summarizes. Dr. Dumois: Oh, yeah. It is essential to follow all public health advice to reduce the risk of reinfection. Amiji says COVID-19s subvariants typically cause more upper respiratory issues than lower, making the symptoms less serious.

Lahita, MD, PhD, director of the Institute for Autoimmune and Rheumatic Disease at Saint Joseph Health, and author of Immunity Strong, pointed out that immunity in the population is so high now due to natural infection or vaccination, and hes hopeful we wont see the pandemic worsen. The window largely associated with earned immunity tends to be closely associated with current guidelines published by the Centers for Disease Control and Prevention (CDC), which maintains that those who have tested positive for COVID-19 shouldn't test again for another 90 days. According to scientists at Imperial College London, after taking into account a host of factors Omicron was associated with.

Stephen Griffin, a virologist at the University of Leeds School of Medicine, believes BA.1, BA.2 and a third Omicron sub-variant that never took off, evolved over the course of chronic infections in a small population of immune-compromised people, before spreading across the globe.

Another study from Belgium looked at 56,000 cases. But hospitalizations still happen, especially among subsets of the population that are at higher risk, so it is still important to take preventative measures even as we start to move into what Amiji calls an endemic phase of the pandemic. Vaccination is more or less effective against different strains of COVID-19. . Researchers may be more concerned about reinfection rates when it comes to the rise of another variant that may impact those who have experienced a primary Omicron infection this winter. It's compounded by the fact that current COVID-19 testing doesn't always allow you to understand which SARS-CoV-2 variant you've been impacted by after testing positive, making it tougher for anyone to confirm if they've even been impacted by Omicron in the first place, though likely due to its current spread.

"Omicron is waning, but if we can learn from the past, it will not be the last strain we will face," Dr. Shah says, adding that the likelihood of serious reinfection would be drastically reduced for a vaccinated individual. Factors that may contribute to reinfection include waning immunity and emerging new variants. As scientists have only studied a dozen of the spike proteins present in the Omicron variant, it is still too early for them to gather information on other mutations and how these would affect the viruss behavior. What happens now? 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. Lahita emphasized that it doesnt matter if someone looks perfectly healthy, or is a top-flight 25-year-old athlete. 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.
