Coronavirus disease 2019 (COVID-19), the respiratory illness caused by severe acute respiratory syndrome coronavirus 2, has affected hundreds of thousands of people. We aim to report the distribution of cases, prevalence, and clinical, radiological, and laboratory signs and outcomes of COVID-19 in paediatric patients. Moreover, we intend to evaluate neonatal clinical outcomes. Hence, our age range of interest is 0 to 19 years. Methods: A systematic literature review was conducted using the Medline database to identify papers published between 1 December 2019 and 9 April 2020 on COVID-19. Results: The search identified 27 relevant scientific papers and letters. The review showed that the prevalence of COVID-19 in the paediatric population accounts for a small percentage of patients, whose clinical signs and symptoms are often milder than those of adults. Despite better prognosis and low mortality in children, the disease can progress to severe pneumonia in some cases, especially in the presence of co-morbidities. Children are likely to become a hidden source of infection because of their

Atrial septal defect (ASD) is a common congenital abnormality, which accounts for 20-40% of all the adult patients with congenital heart diseases. Due to the slow velocity of shunt flow, ASD has a negligible risk for infective endocarditis (IE). However, intravenous drug abuse (IVDA) is a potential cause for IE. IE remains a diagnostic and therapeutic challenge. Our case report demonstrates the atypical presentation of IE in an ASD patient. The diagnosis was made on the basis of modified Duke criteria, and blood cultures were found out to be positive for methicillin-resistant Staphylococcus aureus (MRSA). The treatment for IE was completed in six weeks with full recovery, and the patient underwent a surgery for ASD closure. This case highlights that IE should not be overlooked in ASD patients and that a high index of suspicion, in addition to proper antibiotic therapy, is lifesaving. Also, follow-up, along with rehabilitation measures, should be taken for patients with a history of drug abuse in order to prevent the risk of reinfection.
