That may influence how long youre protected. Science. Historical data on other infectious agents had suggested waiting two to four weeks after a viral infection before getting a viral vaccine since the immune system is ramped up and the protection from the vaccine is likely to be less effective, he added. Should I continue to wear a mask? In fact, according to an August 2022 study published in JAMA Network Open, over 56% of people who were likely infected with Omicron didn't know they even had the virus.

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. "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. 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. Pink eye is most often caused by a viral infection, such as adenovirus, but it can also be caused by bacterial infections, allergies or injuries, per the Mayo Clinic. The fast-growing COVID-19 variant already has a nickname on social media: Arcturus, named after the brightest star in the northern celestial hemisphere. Hay J, Kissler S, Fauver J, et al.

The experts emphasize that we're still learning about XBB.1.16 as it continues to spread. And since no two COVID-19 cases result in the same kinds of symptoms with the same severity, or progression, current breakthrough cases triggered by BA.2.12.1 can lead to any combination of known COVID-19 symptoms that researchers have noted over the course of the pandemic. And data released by the Centers for Disease Control and Prevention (CDC) in mid-May indicates that the latest subvariant may be responsible for upwards of 50% of new COVID-19 cases across the United States. You will then be prompted to answer which vaccines you have received already. 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.

However, the evidence is not clear about how protective Omicron infection is for future infections. According to a May 2022 study published in the journal Otolaryngology Head and Neck Surgery, compared to rates of smell and taste loss during the early phase of the pandemic in 2020 before variants were identified, chances of smell and taste loss were just 17% for Omicron, 44% for Delta, and 50% for the Alpha variant. Omicron and its subvariants have shorter incubation periods, which means it takes less time for symptoms to appear after exposure to the virus. This action includes authorizing the current bivalent vaccines (original and omicron BA.4/BA.5 strains) to be used for all doses administered to individuals 6 months of age and older, including .
