U.S. circumstances of COVID are once more ticking up from the excessive plateau they’ve sat at many of the yr. Transmission of the virus is “substantial” or “excessive” in almost 75% of U.S. counties, in accordance with the U.S. Facilities for Illness Management and Prevention.

When COVID circumstances fail to drop into low-level valleys after mountainous peaks, it’s powerful to inform when a brand new wave is beginning. However as circumstances of as soon as globally dominant BA.5 taper off, new variants just like the BQ household are gaining floor within the U.S. and elsewhere. 

Which means a coming wave of circumstances, consultants say—or a sustained excessive wall of circumstances, doubtlessly, if frequent waves of Omicron variants overlap one another.

What signs ought to one look out for? The quick reply: not essentially the identical signs that signaled COVID in the beginning of the pandemic. 

Dropping the flexibility to scent is now not widespread amongst COVID sufferers, in accordance with the just lately launched Zoe Well being Research, by scientists at Harvard and Stanford universities, along with faculties within the UK. 

Researchers examined information submitted by tens of hundreds of members who logged their signs for analysis functions by way of an app. Signs widespread amongst those that’ve been contaminated with the Omicron variant—presently answerable for the overwhelming majority of circumstances worldwide—who’ve had at the very least one dose of vaccine embrace sneezing, sore throat, nasal congestion, persistent cough, and headache, they discovered.

“In case you’ve been vaccinated and begin sneezing so much with out a proof, it is best to get a COVID take a look at, particularly if you’re residing or working round people who find themselves at higher threat from the illness,” the authors wrote.

These with Omicron had been far much less more likely to expertise mind fog, eye ache, fever, and headache than those that skilled Delta, in accordance with researchers. As well as, these with Omicron who had been vaccinated had been at a decrease threat of hospitalization and tended to be sick for a shorter period of time, when in comparison with these vaccinated who skilled earlier variants.

Whereas COVID sufferers requiring hospitalization throughout the Delta wave in late 2021 tended to have pneumonia-like signs, COVID sufferers throughout the Omicron period extra typically have signs just like the widespread chilly, in accordance with a June article in Infectious Illness Studies. The 4 generally circulating human coronaviruses apart from COVID often current as widespread colds.

The shift probably occurred as a result of the Delta variant tended to thrive within the decrease respiratory system of these contaminated, whereas the Omicron variant, particularly newer strains, tends to thrive within the higher respiratory system. That’s topic to alter, nevertheless, because the virus evolves.

It’s not possible to say whether or not Omicron is much less extreme than Delta, consultants say, as a result of the general public has continued to construct its immunity. When persons are contaminated or vaccinated, it boosts their immune techniques—and whereas antibody immunity lasts just a few months, T-cell immunity, which may make infections milder, lasts for for much longer. 

It’s potential that COVID is turning into extra akin to the seasonal flu, consultants say, with milder signs and circumstances which can be extra widespread throughout winter. However it’s too early to know, they warning, including that the virus may change course at any level.

At this level within the pandemic, it could be tough to tell apart COVID from the flu or one other respiratory virus. In case you’re sick, consultants advocate testing—at-home exams can be found for COVID, after all, physician’s workplaces have fast exams for the flu, and a few lab firms provide at-home exams for each. Individuals who take a look at constructive for both can contact their well being care supplier about prescribing an antiviral like Paxlovid for COVID, or Tamiflu for the flu.
