US changes school guidance, allowing desks to be closer

NEW YORK: Students in the United States can safely sit just three feet apart in the classroom as long as they wear masks but should be kept the usual six feet away from one another at sporting events, assemblies, lunch or chorus practice, the Centers for Disease Control and Prevention said Friday (Mar 19) in relaxing its COVID-19 guidelines.

The revised recommendations represent a turn away from the six-feet standard that has sharply limited how many students some schools can accommodate. Some places have had to remove desks, stagger scheduling and take other steps to keep children apart.

Three feet “gives school districts greater flexibility to have more students in for a prolonged period of time,” said Kevin Quinn, director of maintenance and facilities at Mundelein High School in suburban Chicago.

In recent months, schools in some states have been disregarding the CDC guidelines, using three feet as their standard. Studies of what happened in some of them helped sway the agency, said Greta Massetti, who leads the CDC's community interventions task force.

While there is evidence of improved mental health and other benefits from in-person schooling, “we don't really have the evidence that 6 feet is required in order to maintain low spread", she said.

Also, younger children are less likely to get seriously ill from the coronavirus and don't seem to spread it as much as adults do, and "that allows us that confidence that that 3 feet of physical distance is safe", Massetti said.

The new guidance:

— Removes recommendations for plastic shields or other barriers between desks. “We don't have a lot of evidence of their effectiveness” in preventing transmission, Massetti said.

— Advises at least three feet of space between desks in elementary schools, even in towns and cities where community spread is high, so long as students and teachers wear masks and take other precautions.

— Says spacing can also be three feet in middle and high schools, so long as there is not a high level of spread in the community. If there is, spacing should be at least six feet.

The CDC said six feet should still be maintained in common areas, such as school lobbies, and when masks can't be worn, such as when eating.

Also, students should be kept six feet apart in situations where there are a lot of people talking, cheering or singing, all of which can expel droplets containing the coronavirus. That includes chorus practice, assemblies and sports events.

Teachers and other adults should continue to stay six feet from one another and from students, the CDC said.

CDC Director Dr Rochelle Walensky said the revised recommendations are an "evidence-based roadmap to help schools reopen safely, and remain open, for in-person instruction".

“Safe in-person instruction gives our kids access to critical social and mental health services that prepare them for the future, in addition to the education they need to succeed," she said in a statement.

Last year, the CDC advised that one way for schools to operate safely was by keeping children six feet apart, the same standard applied to workplaces and other settings.

In contrast, the World Health Organization suggested 1m — a little over three feet — was sufficient in schools. The American Academy of Pediatrics says desks should be three feet apart and “ideally” six feet.

The CDC guidance was problematic for many schools that traditionally had 25, 30 or more children per classroom in closely grouped desks. Some schools adopted complicated scheduling that might, for example, have half a class come to school on some days and the other half on other days.

The Ridley School District in suburban Philadelphia took steps like that to follow the six-feet guideline after the CDC emphasised it last summer. But neighbouring communities went with three feet, “and we're not seeing the data really reflect a different spread rate", said Lee Ann Wentzel, the district's superintendent.

The district had already decided to shift to three-feet distancing starting next month and invite all students to attend five days a week. But Wentzel said she was glad to hear of the change in CDC guidance because that will make it easier to explain and defend the district's decision.

A recent study in Massachusetts looked at infections of students and staff members in schools that used the three-feet standard and those that used the six-feet one. It found no significant difference in infection rates.

Massetti said other research has also been influential, including two studies the CDC released Friday.

One was a study in Utah that found low coronavirus transmission rates among students who did a good job wearing masks and whose desks were only three feet apart. The other study, done in Missouri, pointed to a similar conclusion, Massetti said.

The guidance change comes at a time when new, more contagious variants of the coronavirus are increasingly spreading. That means a continued emphasis on mask wearing and other such measures, Massetti said.
