Adults aren’t the only ones who can be “long haulers,” people who suffer from COVID-19 symptoms long after the disease abates. Hospitals around the world are seeing thousands of cases of people who suffered from COVID-19 and are still showing signs of brain fog, fatigue and other ailments months later. Now we are seeing similar patterns among the young.

According to CNN, while COVID-19 symptoms are generally milder in children, the virus can still pose a risk to their health. Experts say that a small percentage may develop an inflammatory syndrome that can trigger longer-lasting symptoms, but currently there is little information on why some kids become long haulers.

“At the moment there’s no concrete data that’s been published in relation to children and long-term problems, but that’s because we are still fairly early on and children haven’t been so badly affected,” Dr. Nathalie MacDermott, a pediatric infectious disease expert with King’s College London, tells CNN. “It’s certainly possible that children may experience the kind of problems we are hearing about in adults such as long-term fatigue.”

Experts have also been concerned that children with COVID-19 may also suffer brain damage. Dr. Omar Abdel-Manna, a pediatric neurology specialist from the Great Ormond Street Hospital in London, told NBC News that he’s concerned about the new-onset neurological symptoms in children with COVID-19.

“The virus has surprised us in so many, many ways,” he said. “It does need really good quality longitudinal assessments and studies that will be looking at the cognition of these children, looking at their long-term psychological and psychiatric health.”

In the meantime, parents with children still suffering from fatigue, breathlessness, chest pains and diarrhea for weeks have turned to the Long Covid Support Group for help and support.
