This can also increase your odds of reinfection with every new COVID-19 wave. The protection provided by vaccination or having had a previous infection is better at stopping the virus from getting into your body and doing serious damage, than it is at keeping the virus out of your nose and throat. These mutations help the virus form new variants and also strengthen the ability of the next strain in infecting an individual. According to Robert Wachter, a professor and chair of the department of medicine at University of California, San Francisco, this is probably not an example of reinfection but something different, known as "rebound," when some patients begin experiencing symptoms and test positive again 2 to 8 days after taking the medication. This includes how soon reinfection can happen. Last medically reviewed on July 27, 2022.

Dr Amesh Adalja, senior scholar at Johns Hopkins Centre for Health Security in the US, agreed: Its unclear, at this point, what level of immunity occurs after an Omicron infection. Thats because COVID-19 tests dont identify variants. Al-Aly Z, et al. (2022). Terms & Conditions. Researchers are studying the newer variants to learn when you might be at the most risk for reinfection. The most recent resurgence in South Africa is now being driven by omicron sub-lineages BA.4 and BA.5. However, theres some evidence that reinfections may increase the risk of lasting health effects. A study published in March found the risk of reinfection "increased substantially" with the emergence of omicron in November, says Juliet Pulliam, lead author of the study and director of the South African Centre for Epidemiological Modelling and Analysis. Much has been said about how quickly Omicron can spread, but another question is its ability to reinfect. That's because COVID-19 tests don't identify variants. "Vaccination vaccination vaccination. Altarawneh HN, et al. Overall, they found that reinfection risk was 6.7% in the 18 to 22 months after a first infection.
