INTRODUCTION
Coronavirus Disease 2019 (COVID-19) is a viral disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Coronaviruses are a large family of viruses that mostly present in mammals and birds (1). Early cases of COVID- humans have a history of going to the Huanan Seafood Wholesale Market in . Therefore, it was initially assumed that animal-to-human transmission was the main mechanism. In a short period of time, cases with no history of visiting the market were reported. Therefore, it was understood that the virus can also be transmitted from human-to-human (2).
The transmission route of COVID-19 disease develops as a result of inhalation of the infected droplet or contact with the surfaces and fomites soiled by infected respiratory secretion during coughing or sneezing of the infected person (3). Comprehensive population-based epidemiological studies have confirmed that SARS-CoV-2 infection is less common in children than in adults and if children do acquire SARS-CoV-2, the vast majority experience mild disease not requiring hospitalization. Children with COVID-19 are reported to get the infection from an adult contact, with minimal secondary transmission from children. Children do not appear to be efficient transmitters of infection (4).
The disease initially presents as a mild respiratory disease and develops into viral interstitial pneumonia, which may progress to acute respiratory distress syndrome (ARDS) and multi-organ failure (MOF) in 10-15% of adults. The course of the disease is generally mild in children compared to adults, the reason for this has not been clear yet (5). Common symptoms in adults infected with COVID-19 include fever, dry cough and fatigue. The symptoms in children are more atypical than in adults, and coughing is lighter. Instead of common symptoms in adults, gastrointestinal symptoms such as diarrhea and vomiting are common in children (1). In this study, we aimed to assess the common symptoms and possible source of infection in pediatric cases with SARS-CoV-2 infection.
