Researchers from the Medical Faculty of the University of São Paulo (FM-USP) and the Adolfo Lutz Institute found that children and adolescents infected with Covid-19 may have clinical symptoms that are different from traditional ones, ie are different from symptoms usually caused by acute respiratory diseases, such as fever, cough, and shortness of breath caused by severe injuries from SARS-CoV-2 in the pulmonary alveoli. According to the study, healthy children infected with Covid-19 may have extrapulmonary inflammatory lesions, such as myocarditis in the heart and colitis (inflammation of the intestinal colon).
The atypical form of Covid-19 is known as pediatric multisystem inflammatory syndrome (SIM-P). The researchers performed an autopsy on five children who died of complications from Covid-1
9 in São Paulo, a boy and four girls between the ages of 7 months and 15 years. “It is important that pediatricians pay attention to these possible clinical manifestations,” said researcher Marisa Dolhnikoff, professor at FM-USP and coordinator of the project.
