The queens image will no longer be printed on British currency. While not likely, its possible to get COVID-19 twice within a 90-day period. Many of these cases are likely to be people who were infected by the Alpha or Delta variants in 2021, and then infected again by the Omicron BA.1 subvariantor its even more transmissible cousin, BA.2.

PCR tests are highly sensitive and detect the genetic material (in this case, RNA) of the virus, which is why they might pick up any lingering inactive viral bits after an infection has subsided. Amiji hopes that one day COVID-19 boosters will combine with flu shots, and that it can be easy to get both at the same time each year.

Studies suggest that reinfection with SARS-CoV-2 with the same virus variant as the initial infection or reinfection with a different variant are both possible; early reinfection within 90 days of the initial infection can occur.99-101 Symptoms during reinfection are likely to be less severe than during the initial infection, but some people can experience more severe COVID-19 during reinfection.99,100,102,103 Both previous infection and vaccination have been shown to provide some protection against infection, although risk of reinfection varies by circulating variant.104-107 Although rates of reinfection might change as new variants emerge, vaccination remains the safest strategy for preventing future SARS-CoV-2 infections, hospitalizations, long-term sequelae, and death.

In Australia, Dr Cromer said the rise in reinfectionswas partly because more people had now been infected with COVID-19, and therefore had the potential to get it again. While data suggests reinfection with Omicron is not uncommon in people who were previously infected with a different COVID-19 variant, it's less clear what protection one Omicron infection confers against another. But you may be surprised to learn that the coronavirus actually doesnt mutate nearly as much as influenza, which changes nearly everything about its appearance from one year to the next. Breakthrough casesare possible even in previously ill people who are fully vaccinated and, if youve had COVID-19 already but arenotvaccinated, you may be at an even higher risk of getting sick again.

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. The good news is that reinfections are likely to be less severe than primary infections, given pre-existing immunity from prior infection and/or vaccination, said mathematical biologistDeborah Cromer. Another reason the CDC advises against asymptomatic testing for 90 days after having COVID-19 is that if you are infected, your immune system is going to generate antibodies, so your immunity to the virus will be boosted, says Mansoor Amiji, university distinguished professor of pharmaceutical sciences and chemical engineering at Northeastern. Distinguishing Multisystem Inflammatory Syndrome in Children From COVID-19, Kawasaki Disease and Toxic Shock Syndrome.
