‘Test-to-stay’ model eyed to spare students from home quarantine

- By Emily Anthes

WHEN THE SCHOOLS in Marietta, Georgia, opened their doors on Aug. 3, the highly contagious Delta variant was sweeping across the South, and children were not being spared.

By Aug. 20, 51 students in the city’s small school district had tested positive for the coronaviru­s. Nearly 1,000 others had been flagged as close contacts and had to quarantine at home for 7-10 days.

“That’s a lot of school, especially for children that are recovering from 18 months in a pandemic where they missed a lot of school or had to transition to virtual,” said Grant Rivera, the superinten­dent of Marietta City Schools.

Last week, the district changed tack. Students who are identified as close contacts can now continue attending school as long as they have no symptoms and test negative for the virus every day for seven days.

An increasing number of school districts are turning to testing to keep more children in the classroom and avoid disrupting the work lives of their parents. The resourcein­tensive approach — sometimes known as “test to stay” or modified quarantine — allows students who have been exposed to the virus to stay in school as long as they take frequent COVID tests, which are typically provided by the school, and adhere to other precaution­s.

Experts agree that children who are infected with the virus should isolate at home, but the question of what to do about their classmates poses a dilemma.

Allowing children who have been exposed to the virus to remain in school does pose a potential transmissi­on risk, and the Centers for Disease Control and Prevention (CDC) says that it “does not have enough evidence” to support the approach. Instead, it recommends that close contacts who have not been fully vaccinated quarantine for as long as 14 days. (Vaccinated close contacts can remain in the classroom as long as they are asymptomat­ic and wear a mask, according to the agency’s school guidance.)

“At this time, we do not recommend or endorse a test-to-stay program,” the CDC said in a statement to The New York Times. The agency added, “However, we are working with multiple jurisdicti­ons who have chosen to use these approaches to gather more informatio­n.”

The CDC guidelines mean that in some cases, especially in classrooms where students are not vaccinated, masked or socially distanced, a single case of COVID can force a dozen or more students out of school. New York City’s school guidelines are even more stringent, stipulatin­g that all unvaccinat­ed students must quarantine for 7-10 days if one of their classmates contracts the virus.

With the academic year barely underway, some districts in Florida, Louisiana, Missouri and other COVID hot spots have already had to quarantine hundreds or even thousands of students. In mid-August, Mississipp­i had nearly 30,000 students in quarantine, according to data reported to the state.

A new study, which was published last week in The Lancet, suggests that the test-to-stay approach can be safe. The randomized controlled trial included more than 150 schools in Britain, and found that case rates were not significan­tly higher at schools that allowed close contacts of infected students or staff members to remain in class with daily testing than at those that required at-home quarantine­s.

Roughly 2% of school-based close contacts ultimately tested positive for the virus, researcher­s found, which means that schools were keeping 49 uninfected students out of class every time one student tested positive.

“When you put that in the broader context of what we’re doing in society, it’s putting a pretty strong penalty on young people, I think,” said Dr. Bernadette Young, an infectious disease expert at the University of Oxford and a lead author of the paper.

This summer, the United Kingdom announced that children identified as close contacts no longer needed to quarantine, although it encouraged them to be tested for the virus.

As school officials embark on a third pandemic academic year, many say the time has come for a new approach.

“The philosophy of this is how can we keep healthy kids in school and sick kids at home?” said Isaac Seevers, the superinten­dent of Lebanon City Schools in Ohio, which is preparing to start a test-to-stay program. “I think there’s some real optimism that this is a game-changer for how we learn to live with COVID.”


Melissa True Gibbs, a mother of two teenagers in Sandy, Utah, prefers not to think about last fall. “It was hell,” she said.

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

By late September, with COVID cases on the rise, the school shut its doors and transition­ed to online learning. Two weeks later, it shifted to a hybrid schedule — in which students came to school on some days and learned from home on others — and then back to in-person and then back to hybrid and then back to entirely online as case numbers rose again.

“My kids are pretty resilient,” Ms. True Gibbs said. “But man, that first half of that year, I saw things happening with my kids that scared me. They weren’t emotionall­y well, they weren’t mentally well, they were struggling.”

Many other schools in Utah were having similar experience­s. So as winter approached, officials developed a test-to-stay protocol. Small schools that had 15 cases, or larger ones that had a 1% infection rate, could either switch to online learning or hold a mass testing event. Students who tested negative could return to class, while those who were infected, or whose families did not consent to the testing, would stay home. —
