When the colleges in Marietta, Ga., opened their doorways on Aug. 3, the extremely contagious Delta variant was sweeping throughout the South, and youngsters weren’t being spared.

By Aug. 20, 51 college students within the metropolis’s small faculty district had tested positive for the coronavirus. Practically 1,000 others had been flagged as shut contacts and needed to quarantine at house for seven to 10 days.

“That’s quite a lot of faculty, particularly for kids which might be recovering from 18 months in a pandemic the place they missed quite a lot of faculty or needed to transition to digital,” mentioned Grant Rivera, the superintendent of Marietta Metropolis Faculties.

Final week, the district modified tack. College students who’re recognized as shut contacts can now proceed attending faculty so long as they haven’t any signs and take a look at adverse for the virus each day for seven days.

An rising variety of faculty districts are turning to testing to maintain extra youngsters within the classroom and keep away from disrupting the work lives of their dad and mom. The resource-intensive strategy — typically generally known as “take a look at to remain” or modified quarantine — permits college students who’ve been uncovered to the virus to remain in class so long as they take frequent Covid assessments, that are usually supplied by the college, and cling to different precautions.

Consultants agree that youngsters who’re contaminated with the virus ought to isolate at house, however the query of what to do about their classmates poses a dilemma.

Permitting youngsters who’ve been uncovered to the virus to stay in class does pose a possible transmission threat, and the Facilities for Illness Management and Prevention says that it “does not have enough evidence” to assist the strategy. As an alternative, it recommends that shut contacts who haven’t been absolutely vaccinated quarantine for so long as 14 days. (Vaccinated shut contacts can stay within the classroom so long as they’re asymptomatic and put on a masks, in accordance with the agency’s school guidance.)

“At the moment, we don’t advocate or endorse a test-to-stay program,” the C.D.C. mentioned in an announcement to The New York Occasions. The company added, “Nonetheless, we’re working with a number of jurisdictions who’ve chosen to make use of these approaches to collect extra info.”

The C.D.C. pointers imply that in some circumstances, particularly in school rooms the place college students usually are not vaccinated, masked or socially distanced, a single case of Covid can drive a dozen or extra college students out of faculty. New York Metropolis’s school guidelines are much more stringent, stipulating that every one unvaccinated students must quarantine for seven to 10 days if one among their classmates contracts the virus.

In mid-August, Mississippi had nearly 30,000 students in quarantine, in accordance with data reported to the state.

A brand new research, which was published last week in The Lancet, means that the test-to-stay strategy may be protected. The randomized managed trial included greater than 150 colleges in Britain, and located that case charges weren’t considerably increased at colleges that allowed shut contacts of contaminated college students or employees members to stay at school with each day testing than at those who required at-home quarantines.

Roughly 2 % of school-based shut contacts in the end examined optimistic for the virus, researchers discovered, which implies that colleges had been preserving 49 uninfected college students out of sophistication each time one pupil examined optimistic.

“Whenever you put that within the broader context of what we’re doing in society, it’s placing a reasonably sturdy penalty on younger individuals, I feel,” mentioned Dr. Bernadette Younger, an infectious illness skilled on the College of Oxford and a lead writer of the paper.

This summer time, the UK introduced that youngsters recognized as shut contacts no longer needed to quarantine, though it inspired them to be examined for the virus.

As faculty officers embark on a 3rd pandemic tutorial yr, many say the time has come for a brand new strategy.

“The philosophy of that is how can we preserve wholesome youngsters in class and sick youngsters at house?” mentioned Isaac Seevers, the superintendent of Lebanon Metropolis Faculties in Ohio, which is making ready to start out a test-to-stay program. “I feel there’s some actual optimism that this can be a game-changer for the way we be taught to reside with Covid.”

Melissa True Gibbs, a mom of two youngsters in Sandy, Utah, prefers not to consider final fall. “It was hell,” she mentioned.

In August, her soccer-playing daughter, Lydia, and theater-loving son, Brody, trudged off to Alta Excessive College.

By late September, with Covid circumstances on the rise, the college shut its doorways and transitioned to on-line studying. Two weeks later, it shifted to a hybrid schedule — during which college students got here to highschool on some days and discovered from house on others — after which again to in-person after which again to hybrid after which again to completely on-line as case numbers rose once more.

“My youngsters are fairly resilient,” Ms. True Gibbs mentioned. “However man, that first half of that yr, I noticed issues taking place with my youngsters that scared me. They weren’t emotionally nicely, they weren’t mentally nicely, they had been struggling.”

Many different colleges in Utah had been having comparable experiences. In order winter approached, officers developed a test-to-stay protocol. Small colleges that had 15 circumstances, or bigger ones that had a 1 % an infection fee, might both swap to on-line studying or maintain a mass testing occasion. College students who examined adverse might return to class, whereas those that had been contaminated, or whose households didn’t consent to the testing, would keep house.

13 colleges, together with Alta Excessive, performed test-to-stay occasions early this yr. Simply 0.7 percent of 13,809 students examined optimistic, researchers reported in Could.

“That made us really feel actually assured that persevering with in-person studying in these colleges was the best name,” mentioned Dr. Adam Hersh, an skilled in pediatric infectious ailments on the College of Utah and a co-author of the paper.

This system saved greater than 100,000 in-person student-days final winter, the researchers discovered.

Ms. True Gibbs mentioned that the testing program allowed her youngsters, who examined adverse, to maintain going to class, observe and rehearsal. “For my youngsters, it made them really feel safer, as a result of they knew the scholars who had been in school weren’t sick,” she mentioned.

In March, the state enacted a law requiring colleges to carry test-to-stay events once they hit sure outbreak thresholds.

Different colleges and districts have adopted comparable options, specializing in testing solely college students who had been recognized as shut contacts.

Some states, together with Illinois, Kansas, California and Massachusetts, have now outlined their very own test-to-stay or modified quarantine protocols, as have some native districts elsewhere. Greater than 2,000 colleges in Massachusetts are utilizing the state’s process, which permits close contacts to stay in school so long as they’re asymptomatic, put on a masks and take a look at adverse for the virus each day for seven days after publicity.

Many dad and mom throughout the nation are thrilled in regards to the new strategy. For Monica Fambrough, who has twin daughters in second grade and a son in fifth grade in class in Marietta, the primary six weeks of faculty had been harrowing.

“We have now, each Friday, type of performed a little bit cheer — we made it by the week with out getting quarantined,” she mentioned. “I simply really feel like each day that I ship them to highschool, we’re sort of rolling the cube that we’re going to get a close-contact discover. And so having the choice to maintain them in class, even when they’re an in depth contact, is a really massive deal for my household.”

Attending class in individual just isn’t solely a greater instructional expertise for her youngsters, she mentioned, but additionally a boon for her and her husband, each of whom work from home.

And a few localities have extra stringent pointers than others. Whereas Massachusetts and Marietta require each day testing for shut contacts, Illinois requires testing each different day and California’s pointers stipulate twice-weekly testing.

Some districts have solved the issue of disruptive quarantines by abandoning the observe altogether. “For those who’re an in depth contact, we’re not requiring that you simply keep house for a quarantine interval,” mentioned Joe Koch, the deputy superintendent of the college district of Waukesha, Wis. The varsity board has taken the strategy that “primarily it’s as much as you ways you wish to handle Covid for your self,” he mentioned.

For the test-to-stay strategy to work, the assessments have to be available and simply accessible. Comparatively few households have opted into Marietta’s program thus far, maybe as a result of they don’t have transportation to the district’s central testing website, Dr. Rivera mentioned. (The district hopes to broaden the variety of testing websites quickly.)

In Bay County, Mich., greater than 300 college students have already been recognized as shut contacts, mentioned Joel Strasz, the county’s well being officer.

“We require that the take a look at be performed on website previous to entry to highschool,” Mr. Strasz mentioned of the test-to-stay protocol. “It’s fairly manageable in the event you solely have to check 5 or 10 youngsters. However if you’ve obtained to check near 100, then that may be difficult, and we needed to scramble to get sources to the colleges.”

Take a look at-to-stay packages are most possible when paired with different security measures, together with masking, specialists mentioned. Utah, which required masks in colleges final yr, has banned such mandates this yr, and a few districts have determined to not do any testing in any respect until they hit the outbreak threshold, mentioned Kendra Babitz, the state’s Covid testing director.

Sturdy testing is a “actually vital” technique for supporting in-person studying, Dr. Hersh mentioned. “However it’s operationally difficult.
