Nature. By Claire Wolters The good news? While a slight majority of Americans have received a full vaccination against COVID-19 sometime over the past few years the figure stands at around 60%, according to public data new variations. Like Arcturus, XBB.1.5 is also considered a variant of interest, per the WHO, and has been circulating widely since last fall. (In MyUCDavisHealth, click on Visits > Schedule Appointment > COVID Vaccination.

The omicron subvariant of COVID-19, BA.5, became one of the dominant strains of the virus in the fall of 2022 in the U.S. At that time, it was the most easily spread strain to date and is able to evade immunity from COVID infection and vaccination. For people who developed severe illness from COVID-19 or have a weakened immune system, the CDC recommends consulting your healthcare provider before ending isolation. Your previous immunity does not protect you from the latest strain. CDC COVID-19 Response Team. The most commonly-reported symptoms with the original Omicron variant were cough, fatigue, headache, congestion, and runny nose. However, its still important to get vaccinated to increase the protection against infection and minimize the risk of severe outcomes from the disease. But despite being more than two years into the COVID-19 pandemic, there's still some confusion as to what having COVID-19 looks like from start to finish, especially as new variants and subvariants continue to pop up. Id recommend getting the second booster at about five months after the first booster.. The FDA has authorized a second updated COVID booster for older people and immunocompromised individuals. Two new subvariants, BA.4 and BA.5, have been gaining ground in the United States. Consider this: Before Omicron, a typical vaccinated 75-year-old who contracted Covid had a roughly similar risk of death around 1 in 200 as a typical 75-year-old who contracted the flu. XBB.1.5 was dominant over the winter and did not appear to drive more severe disease or worse vaccine effectiveness relative to earlier Omicron variants. Though symptoms of Omicron aren't drastically different from those associated with the Delta variant, they are manifesting differently, Pia MacDonald, PhD, MPH, an infectious disease epidemiologist at RTI International, told Health. Prior Omicron infection protects against BA.4 and BA.5 variants. Nature. Khan, K, Karim, F, Cele, Set al. The natural immunity from a COVID-19 infection with Omicron likely lasts about four to six months, similar to other variants. Experts assume that the elderly and those with underlying conditions will have less robust immune protection from an Omicron infection, just as they did to prior variants and to vaccines, Stanley H. Weiss, MD, professor of medicine at the Rutgers New Jersey Medical School, told Verywell. doi:10.1001/jamanetworkopen.2022.27241. How Long Do Breakthrough COVID-19 Symptoms Last?

Although it can vary, people are generally contagious between 1-3 days before omicron symptoms show. "There is no indication at the moment that its causing more severe disease and its not driving more people into the hospitals," says Schaffner. In that case, here's what a typical timeline of an Omicron infection looks like, from exposure to immunity. Antibodies From Vaccines vs. Antibodies From Natural Infection. Feeling sick while experiencing a breakthrough infection is entirely likely, though, as upwards of 60% of all breakthrough illnesses resulted in mild illness that didn't require hospitalization, according to materials published by the American Medical Association (AMA). Omicron and its variants are better able to escape protective immunity from prior vaccination or infection compared with previous variants, Moss said. A new variant of COVID-19 starting to spread around the United States could be responsible for a new symptom that is unlike any we've seen with the virus so far. With omicron, the symptoms also come on more quickly once you're infected.

Studies suggest that Omicron infections can last in the body for up to 10 days. In addition, Omicron can cause reinfection, even in people who have recovered from COVID-19. As far as how long these Omicron symptoms last, research shows that people have acute symptoms for about six to seven daysabout two days shorter than Delta's eight to nine days of acute illness. It's becoming more and more difficult to compare new variants to old variants, because we're getting so much more immunity in the population, Andrew Pekosz, PhD, a virologist and researcher at Johns Hopkins Bloomberg School of Public Health, told Verywell.

Science brief: SARS-CoV-2 infection-induced and vaccine-induced immunity. Omicron BA.5 is more likely to cause less severe illness compared to other variants. It (also) has at least two mutations in the spike proteins that will probably cause it to evade some amount of vaccine-induced immunity or immunity-induced by infection with XBB.1.5, says Pekosz. Most healthy adults still have to wait. As a general rule, breakthrough COVID-19 cases often present symptoms that may affect individuals acutely anywhere from a few days up to two full weeks, Boden-Albala clarifies. "It seems to have a mutation that could make it even more transmissible than some of the other omicron strains. XBB.1.16 is already taking off in the the U.S. and will likely climb, says Ko, and whenever cases go up, there is a potential for COVID-19 hospitalizations and deaths to go up, as well. It certainly seems like when symptoms go away, infectious virus disappears. There isn't one universal answer, but here's what a majority of vaccinated people can expect.

Moderna and Pfizer both have a single-dose bivalent vaccine. Tests can be purchased without a prescription and are available at pharmacies and stores. On April 17, WHO designated XBB.1.16 a "variant of interest." Several studies have found that the incubation period the time it takes to develop symptoms after being exposed is. And while Omicron may be somewhat milder, it spreads more easily than earlier variants, including the Delta variant. "The current recommended vaccines are effective at preventing serious disease for all of the omicron variants," says Schaffner, adding that it seems like they will do the same for XBB.1.16. Everyone's personal COVID calculus is part of a global sum that, right now, is spitting out record-high cases and, in some places, record-high hospitalizations.
