What long COVID means for children

April 23, 2025

Perelman School of Medicine at the University of Pennsylvania researchers found that long COVID can lead to an assortment of health issues in young patients.

Key findings from their studies:

  • Individuals under 21 years of age had a higher risk of kidney problems post-COVID. Specifically, they had a 17% higher risk of chronic kidney disease diagnosis at stage 2 or higher, according to a release. For stage 3 or higher, they had a 35% higher risk. For those that already had kidney disease, the risk of “developing any of several other kidney-related adverse outcomes” was 15% higher.
  • Pediatric patients with COVID had a 25% higher risk of developing gastrointestinal issues than those who did not have COVID. That risk jumped to 28% “in the “chronic phase” from six months to two years after the SARS-CoV-2 test.”
  • Children have an increased cardiovascular risk post-COVID.
  • Certain racial and ethnic groups had higher risk of developing long-COVID.
