Children can carry coronavirus in their noses and throats for weeks even if they don’t show any symptoms, which might explain how the virus can spread silently, researchers in South Korea reported Friday.

“In this case series study, inapparent infections in children may have been associated with silent COVID-19 transmission in the community,” the researchers wrote.

“Interestingly, this study aligns with adult data in which up to 40% of adults may remain asymptomatic in the face of infection,” Dr. Roberta DeBiasi and Dr. Meghan Delaney, both of Children’s National Hospital in Washington, DC, wrote in an accompanying editorial. Neither was involved in the research.

“In this study, the authors estimate that 85 infected children (93%) would have been missed using a testing strategy focused on testing of symptomatic patients alone,” they wrote.

The study comes out at a time when the US Centers for Disease Control and Prevention has been criticized for changing its guidelines on asymptomatic testing, which the American Academy of Pediatrics called “a dangerous step backward” in a statement on Friday
