Falls Church, VA – Last summer, from July to October 2020, Inova Health System partnered with the Virginia Department of Health and George Mason University to conduct a COVID-19 serology (antibody) study to analyze the incidence of COVID-19 in children in Northern Virginia.

The analysis of blood samples from more than 1,000 children, ages 0 to 19 found that the overall antibody positivity rate in children was 8.5 percent (88/1038). COVID-19 antibodies were found in 8.2 percent of white children, 5.3% of black children, 5.7% of Asian children, and 16.2% of children with multiple racial origins. Children identified as Hispanic ethnicity had a 26.6% rate of antibody positivity.  When compared by age groups, the rate was 13.7% in young children (0-5 years), 7.5% in school-age (6-10 years), 5.1% in early adolescents (11-15 years) and 10.8% in older adolescents (16-19 years).

When compared to an adult serology study in Virginia, which reported a COVID-19 antibody positivity rate of 4.4%, the pediatric rate of positivity is nearly double.  The majority (66%) of children who had antibodies had no history of symptoms of COVID-19 infection, which highlights the silent or asymptomatic infection in children, and subsequent risk of transmission of infection to others.

“The pediatric serology project unexpectedly found more children were seropositive than we had anticipated,” said Rebecca Levorson, MD, Division Director for Pediatric Infectious Diseases, Inova Children’s Hospital.  “Most of these children did not have symptoms, which makes it difficult to know who may be infectious and who is not at a specific time.  Nearly a quarter of the U.S. population is children, and as they may represent a larger proportion of SARS-CoV-2 disease than we previously thought, we need to recognize that children will continue to be infected with and possibly asymptomatically spread this disease. As we continue to fight this pandemic, we need to consider ways to protect them and others by using the tools we have available to us, including masking, social distancing and vaccination.”
