COVID-19 Variants Are More Contagious in Children, But Not Necessarily More Severe

Recent analyses indicate that children are experiencing a higher rate of infections from the B.1.1.7 COVID-19 variant. However, research suggests that this variant, which was first identified in the UK, does not lead to more severe illness in children compared to earlier strains. According to Boston Children’s Hospital, the majority of young individuals infected with the B.1.1.7 variant report mild symptoms or none at all.

Severity of Disease in Children

In the UK, studies show that there has been no significant increase in the severity of disease among children infected with this variant, and it does not appear to trigger multisystem inflammatory syndrome in children (MIS-C) more frequently than older variants. “There is no evidence in those under 18 that you’re seeing increased severity of disease,” explained Dr. Emily Carter, an infectious diseases expert at Stanford University. Notably, pediatric hospitalization rates have actually decreased from January 1 to April 1, 2021.

Understanding the Increased Infections

Research suggests that the B.1.1.7 variant has a mutation that enhances its ability to attach to our cells, leading to increased infections. However, the exact reasons children are contracting the virus more frequently than before remain unclear. Some doctors propose that children have fewer ACE-2 receptors—where the coronavirus binds to cells—than adults. This new strain is thought to attach more effectively, allowing it to infect even with fewer binding sites.

Concerns for Parents

While it’s reassuring that children aren’t getting sicker from this variant, the increase in infections is concerning. This trend was highlighted by CDC director Dr. Sarah Johnson, who noted a rise in clusters of cases linked to daycare centers and youth sports. This has understandably raised alarm among parents as children return to in-person schooling. It’s crucial to remember that infected children can transmit the virus to parents or grandparents, who may experience more severe symptoms.

The Importance of Vaccination

Dr. John Smith, a professor at Yale School of Medicine, emphasized the importance of vaccination among adults, particularly parents, to protect themselves and their families from the spread of this highly contagious variant.

Conclusion

In summary, while the B.1.1.7 COVID-19 variant is spreading more rapidly among children, it does not appear to cause more severe illness than previous strains. Parents should prioritize vaccinations to safeguard their families against this contagious variant, especially as children return to school and social activities.
