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. The new Omicron subvariant, known as BA.2.12.1 by researchers currently chronicling its spread, has been purported to be 25% more contagious than earlier Omicron strains and has led to an uptick in breakthrough COVID-19 cases. Here's what to know, If you've had COVID-19, here's what you need to know about blood clots, New study uncovers the 7 most common long COVID symptoms.

This way, they can potentially get a prescription for Paxlovid, an antiviral medication used to help prevent severe illness from the disease. 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 average peak is going to be on day two from when it was detected via a test," MacDonald said. If you know you had contact with an infected person, particularly in a higher-risk situation (such as an indoor space for a longer period with others who werent masked), testing is advised. Sharma noted that, in general, symptoms appear to be shorter and milder in vaccinated people compared to unvaccinated people. But experts have eagerly documented current and earlier Omicron-based outbreaks in major cities across the country, allowing them to have a better idea of how well vaccines are protecting individuals and influencing recovery periods in 2022. According to Dr. Adalja, Omicron's short incubation period may be influenced by built-up immunity from the past two years. Here's what you need to know.

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. How long am I contagious with an omicron subvariant? Four doses of an mRNA vaccine has been providing excellent protection against severe disease from Omicron, but incomplete protection from acquiring infection, Weiss said. More than 70 percent of people there have been exposed to the coronavirus . Two new subvariants, BA.4 and BA.5, have been gaining ground in the United States. Jansen L, Tegomoh B, Lange K, et al.

Whether changes in duration of infection are a result of variant characteristics or the public's vaccination status is unclear. How Long Will Immunity Last With the New COVID Bivalent Booster? UC Davis Health patients can use the MyUCDavisHealth symptom tracker to evaluate whether to seek help. Because of this, it may be able to "outrun" or outcompete other variants, he adds. How long do omicron subvariant symptoms last?

The natural immunity from a COVID-19 infection with Omicron likely lasts about four to six months, similar to other variants. "They're starting to do this the way we do routinely with our influenza vaccine, which we update on an annual basis," says Schaffner, adding that annual boosters could become a norm in the future, especially for higher-risk groups. A quick displacement of the SARS-CoV-2 variant Delta with Omicron: Unprecedented spike in COVID-19 cases associated with fewer admissions and comparable upper respiratory viral loads.
