Aug. 10, 2023 – Greater than 3 years into the COVID-19 period, most Individuals have settled again into their pre-pandemic life. However a brand new dominant variant and rising hospitalization numbers could give approach to one other summer time surge. 

Since April, a brand new COVID variant has cropped up. In line with latest CDC information, EG.5 – from the Omicron household – now makes up 17% of all circumstances within the U.S., up from 7.5% within the first week of July. 

A abstract from the Heart for Infectious Illness Analysis and Coverage on the College of Minnesota says that EG.5, nicknamed “Eris” by well being trackers, is almost the identical as its guardian pressure, XBB.1.9.2, however has one additional spike mutation. 

Together with the information of EG.5’s rising prevalence, COVID-related hospitalization charges have elevated by 12.5% within the final week – essentially the most vital uptick since December. Nonetheless, no connection has been made between the brand new variant and rising hospital admissions. And up to now, consultants have discovered no distinction within the severity of sickness or signs between Eris and the strains that got here earlier than it. 

Trigger for Concern?

The COVID virus has an incredible tendency to mutate, says William Schaffner, MD, a professor of infectious ailments at Vanderbilt College in Nashville. 

“Happily, these are comparatively minor mutations.” Even so, SARS-CoV-2, the virus that causes COVID-19, continues to be extremely contagious. “There is no doubt that it is spreading – but it surely’s no more critical.”

So, Schaffner doesn’t suppose it’s time to panic. He prefers calling it an “uptick” in circumstances as a substitute of a “surge,” as a result of a surge “sounds too large.”

Whereas the numbers are nonetheless low in comparison with final yr’s summer time surge, consultants nonetheless urge individuals to remain conscious of adjustments within the virus. “I don’t suppose that there’s any trigger for alarm,” agreed Bernard Camins, MD, an infectious illness specialist at Mount Sinai Hospital in New York Metropolis.

So why the upper variety of circumstances? “There was a rise in COVID circumstances this summer time, in all probability associated to journey, socializing, and dwindling masking,” mentioned Anne Liu, MD, an allergy, immunology, and infectious illness specialist at Stanford College. Even so, she mentioned, “due to an present stage of immunity from vaccination and prior infections, it has been restricted and case severity has been decrease than in prior surges.” 

What the Official Numbers Say

The CDC not updates its COVID Information Tracker Weekly Assessment. They stopped in Could 2023 when the federal public well being emergency ended.

However the company continues to trace COVID-19 circumstances, hospitalizations, emergency division visits, and deaths in several methods. The important thing takeaways as of this week embody 9,056 new hospitalizations reported for the week ending July 29, 2023. That’s comparatively low, in comparison with July 30, 2022, when the weekly new hospitalization numbers topped 44,000. 

“Final yr, we noticed a summer time wave with circumstances peaking round mid-July. In that sense, our summer time wave is coming a bit later than final yr,” mentioned Pavitra Roychoudhury, PhD, an assistant professor and researcher on the College of Washington College of Medication’s Vaccine and Infectious Illness Division. 

“It’s unclear how excessive the height will likely be throughout this present wave. Ranges of SARS-CoV-2 in wastewater, in addition to the variety of hospitalizations, are presently decrease than this time final yr.” 

For a part of the pandemic, the CDC beneficial individuals monitor COVID numbers in their very own communities. However the company’s native steering on COVID is tied to hospital admission ranges, that are presently low for greater than 99% of the nation, even when they’re growing. 

So, whereas it’s excellent news that hospitalization numbers are smaller, it means the company’s capacity to establish native outbreaks or sizzling spots of SARS-CoV-2 is now extra restricted. 

It’s not simply an uptick in hospitalizations nationwide, as different COVID-19 indicators, together with emergency room visits, optimistic assessments, and wastewater ranges, are growing throughout the USA. 

When it comes to different metrics: 

  • On June 19, 0.47% of ER visits resulted in a optimistic COVID prognosis. On Aug. 4, that price had greater than doubled to 1.1%. 
  • On July 29, 8.9% of people that took a COVID take a look at reported a optimistic consequence. The positivity price has been growing since June 10, when 4.1% of assessments got here again optimistic. This determine solely contains take a look at outcomes reported to the CDC. Outcomes of dwelling testing stay largely unknown. 
  • The weekly share of deaths associated to COVID-19 was 1% as of July 29. That’s low, in comparison with earlier charges. For instance, for the week ending July 30, 2022, it was 5.8%.

What About New COVID Vaccines?

So long as you proceed to make knowledgeable choices and get the brand new Omicron vaccine or booster as soon as it’s out there, consultants predict decrease hospitalization charges this winter. 

“Everybody ought to get the Omicron booster when it turns into out there,” beneficial Dean Winslow, MD, a professor of medication at Stanford College in California. 

Within the meantime, “You will need to emphasize that COVID-19 goes to be with us for the foreseeable future,” he mentioned. For the reason that signs linked to those newer Omicron subvariants are usually milder than with earlier variants, “if one has even gentle chilly signs, it’s a good suggestion to check your self for COVID-19 and begin therapy early if one is aged or in any other case at excessive danger for extreme illness.”

Schaffner stays optimistic for now. “We anticipate that the vaccines we presently have out there, and positively the vaccine that’s being developed for this fall, will proceed to forestall extreme illness related to this virus.”

Though it’s tough to foretell an actual timeline, Schaffner mentioned they might be out there by the tip of September. 

His predictions assume “that we do not have a brand new nasty variant that crops up someplace on the planet,” he mentioned. “[If] issues proceed to maneuver the best way they’ve been, we anticipate that this vaccine … will likely be actually efficient and assist us hold out of the hospital throughout this winter, once we anticipate extra of a rise of COVID as soon as once more.” 

Requested for his outlook on vaccine suggestions, Camins was much less sure. “It’s too quickly to inform.” Steerage on COVID photographs will likely be primarily based on outcomes of ongoing research, he mentioned. “It will be prudent, nevertheless, for everybody to plan on getting the flu shot in September.”

Keep Alert and Keep Sensible

Cautious optimism and a name to stay vigilant seem to be the consensus in the mean time. Whereas the numbers stay low up to now and the uptick in new circumstances and hospitalizations are comparatively small, in comparison with previous situations, “It is smart to spice up our anti-Omicron antibody ranges with immunizations earlier than fall and winter,” Liu mentioned. 

“It’s simply advisable for everybody – particularly those that are at larger danger for hospitalization or dying – to remember,” Camins mentioned, “to allow them to type their very own choices to take part in actions that will put them in danger for contracting COVID-19.”

We now have to remind ourselves that whether or not they’re for the flu, COVID, and even RSV, these respiratory virus vaccines work greatest at protecting us out of the hospital. They don’t seem to be nearly as good at stopping milder infections. 

Schaffner mentioned, “So if we do not anticipate perfection, we can’t be so disenchanted.”
