Younger kids more likely to spread SARS-CoV-2 to family members. A recent study looked at the likelihood of children of different age groups transmitting SARS-CoV-2 to household members.
The study found that children under 4 years old were more likely to spread the virus to their household members compared to adolescents aged 14–17 years.
Concern about the safety of children is growing due to the reopening of schools and the increases in the number of COVID-19 cases following the rapid spread of the SARS-CoV-2 Delta variant.
The research revealed that children are more likely to be asymptomatic or have mild symptoms compared with adults. For the study, the researchers compared the ability of children to transmit the virus with that of adults. They recently compared the risk of transmission of SARS-CoV-2 to household members between younger and older children.
The overall study discovered that young kids, especially those aged 0–3 years, were more likely to transmit the virus to their parents and siblings than adolescents aged 14–17 years.
The study results appear in the journal JAMA pediatrics.
The researchers found that children younger than 5 years old are more likely to spread the virus than older children and adults.
“It is essentially impossible for parents to isolate from their sick infants, compared to adolescents who can isolate themselves within the home. Our findings do not mean that children are more [likely to transmit the virus], just that once younger kids have contracted the virus, they have a higher risk of spreading it in the home,” Study co-author Dr. Kevin Schwartz.
