"Immunity wanes over time, making herd immunity a moving target," Boden-Albala says. At-home COVID tests, also known as rapid antigen tests, are useful because they provide quick results. For vaccinated people, emergency room or hospital stays are also typically shorter with the omicron subvariants . Claire Wolters is a staff reporter covering health news for Verywell. The CDC has some pretty specific rules centered on isolation time with COVID-19, regardless of the variant: If you test positive, regardless of vaccination status, you should isolate at home for five full days.

That may influence how long youre protected. What Is Croup and Its Link to COVID-19 in Children? Nature. Even if XBB.1.16 is better at evading immunity from the vaccine, it can still provide some protection, the experts note. Are COVID-19 vaccines effective in protecting against omicron BA.5?

Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. What are the differences between flu symptoms and omicron symptoms? "Breakthrough cases occur when COVID-19 variants evade the body's immune response but most breakthrough cases are asymptomatic or mild, due to the vaccinated person having built-up immunity against the virus. But a few existing studies suggest people are unlikely to remain infectious after 10 days. "This leaves open the opportunity for new variants that evade the vaccines to emerge, so we need to continue to vaccinate as much of the U.S. and global population as possible.". "If you got infected with any of the versions of Omicron there is probably good cross-protection of BA.1 and BA.2and maybe less so with BA.4 and BA.5but for the immediate period of a couple of months to several months after infection, it's unlikely that you'll get [re]infected," Dr. Adalja said. The BA.5 subvariant of Omicron dominated COVID-19 case counts in the U.S. in 2022. Is omicron BA.5 able to spread more easily than other COVID-19 strains? You can schedule your bivalent vaccine through, (non-patients without a login will have to create an account) or by calling, . Omicron and its iterations likely aren't going away anytime soon, and you may still contract the virus (although likely a milder version) even if you have been vaccinated or boosted, or have had a previous case of COVID-19.

Some of the earliest information on the duration of the virus comes from a study that looked at one of the. 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. The Omicron variant is more capable of evading natural immunity, and the interval between infection and reinfection with COVID-19 may be shorter. Those with COVID-19 typically develop symptoms 3-4 days after being infected. 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. Theres nothing particularly worrisome about this variant outside of a few mutations that may make it a little bit more resistant to immunity, says Pekosz.

Weiss, MD, professor of medicine at the Rutgers New Jersey Medical School, told Verywell. 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. 2021;181(10):14071408. At least three studies have found that people infected with omicron still have virus levels high enough to be contagious more than five days after their symptoms began. Scientists found that the updated booster's real-world effectiveness against symptomatic infection for the first three months . So answers, including how sick does omicron make people and how well do vaccines hobble it, can't come fast enough. However, reinfection can still occur earlier than that. This way, they can potentially get a prescription for Paxlovid, an antiviral medication used to help prevent severe illness from the disease.

The immunity from infection with Omicron appears to last about as long as the infection with earlier variants, William Moss, MD, executive director of the International Vaccine Access Center at the Johns Hopkins Bloomberg School of Public Health, told Verywell. That said, the length of symptoms varies greatly depending on the person, their vaccination status, the severity the disease, and any risk factors. Similar to the previous variants of SARS-CoV-2, an infection with Omicron likely confers natural immunity against COVID-19 for several months. This is the same timeframe observed during the Delta wave, but slightly shorter than the two week endurance of the initial COVID-19 strain. But why. While these mutations may give XBB.1.16 an advantage in terms of its ability to spread in the population and escape immunity, says Ko, there is not enough evidence yet to know the exact severity of illness it causes. For the most recent updates on COVID-19, visit ourcoronavirus news page. Immune boosting by B.1.1.529(Omicron) depends on previous SARS-CoV-2 exposure.

That incubation period is just about three days, compared to the Delta variant's five-day incubation period, and the original SARS-CoV-2 virus' incubation period of more than 5 days, according to a December 2021 report published in the CDC's Morbidity and Mortality Weekly Report (MMWR).
