What about children who are sick at school?
The debate moved to discussing what should be done when a child is sick at school. Dr. Panciu clarified recommendations by the CDC regarding what steps to take if a student displays signs of infection consistent with COVID-19: Should they test positive, they are to stay at home for 10 days from the time signs and symptoms first appeared. Further, any teachers or students identified as close contacts are advised to stay at home for 14 days. (Since the ESPID meeting, the CDC has made changes in quarantine times for COVID-19. People can now quarantine for 10 days without a COVID-19 test if they have no symptoms. Alternatively, a quarantine can end after 7 days for someone with a negative test and no symptoms. The agency recommends a polymerase chain reaction test or an antigen assay within 48 hours before the end of a quarantine.)
A significant problem is the overlap between COVID-19 symptoms and those associated with other common illnesses because of a range of viruses. This is particularly true in younger children who often suffer from viral infections. “It is common for children to have up to eight respiratory illnesses a year,” explained Dr. Panciu, “and some may have symptoms so mild that they don’t notice them.”
“We need to be a little bit more children focused, otherwise we are going to be isolating children all the time,” said Dr. Buonsenso. The Royal College of Paediatrics and Child Health state that a child with a simple runny nose or sporadic cough without a fever, who would have attended school in other times, should not be tested for COVID-19. He moved on to then cite several studies that show little or no evidence of COVID-19 transmission between school children. This included a prospective cohort study in Australia showing that child-to-child transmission occurred in 0.3%. “To date, the advantages from routine quarantine and over testing seem too low to balance the social consequences on children and families,” he concluded.
As the debate drew to a close, Dr. Panciu reported several studies that did demonstrate transmission between school-age children. Data from an overnight camp in Georgia where the median age was 12 years showed the attack rate was 44% for ages 11-17 years and 51% for ages 6-10 years. Similar conclusions were reached in an Israeli study looking at a large COVID-19 outbreak in a school. This occurred 10 days after reopening, in spite of preventive measures being in place. “Opening safely isn’t just about the adjustments a school makes,” she said, “it’s also about how much of the virus is circulating in the community, which affects the likelihood that students and staff will bring COVID-19 into their classrooms.”
Damian Roland, consultant and honorary associate professor in pediatric emergency medicine at the University of Leicester (England), commented: “Maximizing educational potential while reducing the spread of COVID19 is a challenge laden with scientific equipoise while simultaneously infused with emotion. The evidence of transmission between, and infectivity from, children is not complete, as this debate has demonstrated. It is important scientists, clinicians, educators, and policy makers make collaborative decisions, aware there is not one perfect answer, and willing to understand and incorporate others views and objectives rather than holding onto single beliefs or approaches.”
