    Abstract Since the start of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic, it has been clear that most children who have been infected with the virus remain asymptomatic or very mildly ill. Since asymptomatic children are less often examined, the true prevalence of asymptomatic SARS-CoV-2 infection is probably underestimated. Children rarely get anosmia/ageusia, yet it is the best indicator of a positive SARS-CoV-2 test. Children with coronavirus disease-2019 (COVID-19) generally have a lower risk of hospitalization and potentially fatal consequences. Immunization with effective and safe vaccine in children and adolescents is likely to provide protection against severe COVID-19 infection. Recent results from COVID-19 vaccine studies indicate good efficacy and tolerability in children.

    Abstract The global pandemic infectious disease that was named the new coronavirus disease (COVID 19), spread throughout the world, causing a major public health emergency. The causative virus of COVID-19, called SARS CoV-2, can infect all age groups. Various clinical signs and symptoms have been observed in neonates, children, and adolescents during the COVID-19 outbreak. The clinical manifestations of COVID-19 might be different due to the medical conditions and comorbid status in elderly and pediatric patients. The rise in cases among children has been reported during the COVID-19 pandemic. Although infected children generally appear to be asymptomatic or have only mild symptoms, COVID-19 in children may also involve a wide spectrum of clinical manifestations ranging from asymptomatic carriers to life-threatening and fatal diseases, as COVID-19 is a systemic disease that can affect multiple organs. Due to the lack of knowledge in the current literature, it is necessary to describe the atypical clinical features, including extrapulmonary manifestations, in pediatric patients with COVID-19. This review is conducted to identify knowledge gaps regarding the broad spectrum of clinical signs and symptoms of children with COVID-19.

    Abstract Coronavirus disease (COVID-19) was firstly reported at the end of 2019. The disease rapidly spread all around the world in a few months and was declared a worldwide pandemic by WHO in March 2020. By April 9, there were 1,436,198 confirmed COVID-19 cases in the world, nearly with 6% mortality rate. This novel infectious disease causes respiratory tract illness that may generally occur as mild upper respiratory tract disease or pneumonia. In older patients and/or patients with underlying conditions, it may result in acute respiratory distress syndrome, multi organ failure and even death. According to the current literature, children account approximately for 1%–5% of diagnosed COVID-19 cases. Generally, COVID-19 seems to be a less severe disease for children than adults. Approximately 90% of pediatric patients are diagnosed as asymptomatic, mild, or moderate disease. However, up to 6.7% of cases may be severe. Severe illness is generally seen in patients smaller than 1 year of age and patients who have underlying disesases. The epidemiological and clinical patterns of COVID-19 and treatment approaches in pediatric patients still remain unclear although many pediatric reports are published. This review aims to summarize the current epidemics, clinical presentations, diagnosis, and treatment of COVID-19 in pediatric patients.

    Abstract Objective: The aim of this study is to review the current evidence on the vertical transmission of SARS CoV-2.
    Methods: Combination of the following keywords; COVID-19, SARS CoV-2, placenta, vertical transmission, intrauterine infection, breast milk were searched in databases.
    Results: In the 50 studies included, 17 newborns testing positive for SARS CoV-2 by RT-PCR were reported. In three neonates, SARS-CoV-2 IgG and IgM levels were elevated. Eight placental tissues testing positive for the virus were reported. Three positive RT-PCR results of test of breast milk have been reported recently. One amniotic fluid testing positive was reported.
    Conclusion: Possible vertical transmission of SARS CoV-2 has been observed in some studies currently. More RT-PCR tests on amniotic fluid, placenta, breast milk and cord blood are required.
