Abstract

In this article, we have reviewed the prevalence, diagnosis, symptoms, and treatment of COVID-19 in children. The incidence of COVID-19 among children under 18 years was 2.1 based on the reported studies, where the mortality rate in the same age group was 0.2. No death has been reported in children under 9-years old. There are some articles that report children with COVID-19 having symptoms similar to Kawasaki's disease. In these cases, heart complications were observed. The best markers for diagnosing the severity of the disease in children are the levels of bilirubin and hepatic enzymes. Large number of angiotensin converting enzyme 2 (ACE2) receptors on cell surfaces, effective innate immune system, and high level of blood lymphocyte have been reported to be the potent reasons for lower incidence of severe symptoms of COVID-19 among children. Children can very well be the carriers of this virus. Children with severe COVID-19 clinical symptoms, especially those suffering from pneumonia, must be hospitalized similar to adults, while quarantine is required for those having mild symptoms. Antiviral medication (lopinavir, darunavir, favipiravir, remdesivir, ribavirin, oseltamivir, tocilizumab, and umifenovir), ACE inhibitors, interferon-alpha 2b, co-therapy with azithromycin, inhaling iNO, and oxygen therapy can be used for treatment. For the treatment of children without any clinical and infection symptoms, home isolation protocol has been recommended.
