COVID-19 can cause long-term lung damage to children and teens Children Coronavirus Disease COVID Lungs LungDamage LongCOVID radiology_rsna
Children and adolescents with severe acute respiratory syndrome coronavirus 2 infection experience a milder course than adults and recover within a few weeks. The definition of a symptom varies; therefore, there is inconsistent reporting of persistent symptoms, which can last for several months after infection and range from 0% to 66%. The fact that there are more unbiased results on post-acute sequelae and symptoms among younger patients further complicates these conclusions.
In the study, long COVID was defined as having symptoms that persisted for at least 12 weeks and met one of the four criteria listed below: Symptoms that persisted after the acute COVID-19 phase or its treatment, symptoms that triggered a new health restriction, new symptoms that appeared after the acute phase but were recognized as a result of COVID-19 disease, and worsening of pre-existing comorbidity.

In addition to shortness of breath, 9% of the participants experienced headache, 28% had dyspnea, 2% had pneumonia, 7% had anosmia, 2% reported ageusia, 7% had fatigue, 11% had impaired attention, and 2% experienced limbic pain. In 22% of the healthy volunteers, 5% of the recovered patients, and 10% of the long COVID-19 patients, pre-existing diseases were found. During the acute phase of the infection, four subjects with RT-PCR-positive SARS-CoV-2 infection did not exhibit any symptoms.
