A summer season wave of COVID-19 is rising.
“There’s clearly a bump,” says William Schaffner, an infectious ailments skilled at Vanderbilt College Medical Middle in Nashville. The medical middle has seen a gradual enhance of hospital admissions for COVID-19 over the previous three weeks, Schaffner says. “That was solely anticipated, I’m afraid.”
Annually, peaks of COVID-19 seem in the summertime and once more within the winter. Not like influenza, which practically disappears in the summertime, SARS-CoV-2, the virus that causes COVID-19, hasn’t settled right into a seasonal sample (SN: 1/29/24). It spreads each time and wherever individuals collect indoors.
“That is an endemic virus that basically can’t be prevented should you’re going to be interacting with people,” says Amesh Adalja, an infectious ailments doctor and senior scholar on the Johns Hopkins Bloomberg Faculty of Public Well being.
COVID-19 has gotten much less extreme due to immunity from vaccines and prior infections and to remedies for the virus, Adalja says. Not like earlier summer season waves, this one isn’t overwhelming hospitals.
Wastewater surveillance knowledge — one of many solely methods to gauge unfold of the virus — point out that viral variants are surging throughout the US, particularly in western states and in locations that had delicate winter seasons. And the variants circulating now are “extremely infectious,” Schaffner says.
Summer season surge
Excessive or very excessive ranges of SARS-CoV-2, the virus that causes COVID-19, have been present in wastewater in about half of U.S. states, particularly in western states.

One variant on the rise is a great-great-great-grandchild of omicron referred to as KP.3.1.1. Like different omicron offspring, it has a number of mutations within the spike protein, together with one which helps it evade antibodies produced after an an infection with current variants or immunization with one in all final fall’s model of the vaccines, researchers report July 17 in a preprint posted to bioRxiv.org.
The rising tide of infections is more likely to final into August, Schaffner says, however there are issues individuals can do to keep away from getting sick.
The right way to keep away from getting COVID-19
Are likely to your immunity by getting vaccinated towards the coronavirus, Schaffner advises. That’s particularly necessary for older individuals and folks with medical circumstances resembling diabetes that put them at larger danger for extreme illness. An estimated 6.6 p.c of adults in the US are immunocompromised, researchers reported in JAMA in February. These individuals are particularly weak, Schaffner says.
Immunity from final yr’s vaccination has in all probability waned. The U.S. Facilities for Illness Management and Prevention say that high-risk individuals, particularly individuals 65 and older, ought to take into account getting vaccinated every now and then get up to date vaccines within the fall. Vaccines are good for stopping extreme illness and hospitalization, however the present ones aren’t efficient for blocking an infection, Adalja says. Vaccination can also assist forestall lengthy COVID (SN: 7/17/24).
It’s also possible to put on an N-95 or KN-95 masks. “And you need to put them on accurately,” Schaffner says. “Carrying them under the nostril or in your brow … doesn’t assist in any respect.”
Individuals in high-risk teams, resembling those that are immunocompromised, can get a monoclonal antibody referred to as Pemgarda to assist shield towards an infection, Adalja says.
What to do should you get sick
When you’re sick now, take a check to see if it’s COVID-19, however don’t be too fast to dismiss the chance if the result’s damaging. A damaging check might imply the immune system is conserving the coronavirus in test or that you just’ve come down with a special sickness, Adalja says. A second at-home check or a PCR check at a health care provider’s workplace could give a clearer reply.
Isolate your self till you’re feeling higher and don’t have a fever for not less than 24 hours, the CDC suggested in up to date tips launched in March. That goes for any respiratory sickness. Some individuals with COVID-19 by no means develop fevers so they should use common sense to determine once they can exit safely, Schaffner says. The CDC advises exercising warning for not less than 5 days after signs enhance and sporting a masks when interacting with others.
Common sense additionally helps right here, Schaffner says. Take into consideration who you’ll see and the way lengthy you’ll be in an enclosed house with them. Possibly postpone the go to to grandma within the nursing residence and the hours-long poker sport and take a stroll exterior as an alternative, he says.
Individuals in high-risk teams may profit from taking antiviral medication resembling Paxlovid or molnupiravir. Paxlovid shaves solely someday off the period of sickness for vaccinated individuals, a end result that isn’t statistically significant, researchers reported April 4 within the New England Journal of Medication. Some research recommend Paxlovid could assist forestall lengthy COVID, however others have discovered that it doesn’t assist (SN: 3/31/23).
COVID-19 is just not going away, Adalja says. There’ll all the time be new variants inflicting recent rounds of an infection, however “drugs and science have given us large quantities of instruments to take care of this virus, greater than for another respiratory virus.”
