COVID-19 için halen spesifik etkili bir tedavi yoktur. Özellikle yetişkin hastalarda yayınlanmış ve devam etmekte olan birçok çalışma bulunmaktadır. Pediatrik hastalarda tedavi seçenekleri yetişkin hastalarda kullanılan ajanlara göre belirlenmektedir. Coronavirüs hastalığı 2019 (COVID-19) neredeyse çoğu çocukta hafif olarak geçirilmesine rağmen, hastaların küçük bir kısmında ciddi veya kritik hastalık gelişebilmektedir. Çocuklarda semptomlar ve hastalık seyri hafif olduğundan destekleyici tedavi tedavinin temelini oluşturur. Çocuklarda COVID-19'u tedavi etmek için kullanılabilecek, randomize kontrollü çalışması olan herhangi bir ilaç bulunmamaktadır. Bununla birlikte, kliniği ağır olan vakalarda, yetişkinlerde kullanılan ilaçlar vaka bazında değerlendirilirmekte ve kullanılabilmektedir. Çocuklarda COVID-19 için potansiyel tedavilerin güvenliğini ve etkinliğini daha iyi tanımlamak için iyi tasarlanmış kontrollü klinik çalışmalara artan bir ihtiyaç vardır.

Currently, there is not any specific effective treatment for COVID-19. There are many studies published and ongoing especially on adult patients. Treatment options in pediatric patients are determined according to the agents used in adult patients. Although coronavirus disease 2019 (COVID-19) is mild in nearly all children, a small proportion of pediatric patients develop severe or critical illness. Supportive therapy forms the basis of the treatment as the symptoms and disease course in children are mild. There are currently no randomized controlled trials of drugs that can be used to treat COVID-19 in children. However, in severe clinical cases, the drugs used in adults are evaluated and used on a case-by-case basis. There is a growing need for well-designed controlled clinical trials to better define the safety and efficacy of potential treatments for COVID-19 in children.
