Symptoms of children and adolescents infected with SARS-CoV-2 variants alpha, delta or omicron

Abstract

AbstractSymptoms experienced by children and adolescents with SARS-CoV-2 infections in the alpha, delta and omicron variant dominated phases were investigated using an online survey, and the frequencies of reported symptoms and changes over time were analyzed. The most prevalent symptoms were fever above 38 °C, tiredness, headache, runny or blocked nose, sneezing and dry cough. Lethargy and nausea were reported significantly more frequently in the omicron variant dominated phase than in the earlier phases of the pandemic. Compared to symptoms reported by adults, fever and gastrointestinal symptoms were reported more frequently for children, especially in the omicron variant dominated phase, whereas the frequency of loss of smell and loss of taste was significantly lower in children than in adults.
