Aim: The study aims to find whether children are essentially immune to COVID-19. Introduction: Immune is the resistance to a particular infection or toxin owing to the presence of antibodies or sensitized white blood cells. The novel coronavirus has been named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), whereas the disease associated with it is referred to as COVID-19. The diagnostic methods that are involved exclusively are RNA detection by reverse transcription-polymerase (RT-PCR) of secretions through nasopharyngeal and throat swabs and in stool samples. Materials and Method: In this review, various articles were searched through search engines like Google Scholar and Pubmed using keywords like immunity in children, resistance, COVID-19 in adults, COVID-19 in children, asymptomatic, less susceptible and milder symptoms. Over 70 articles were collected and reviewed thoroughly. Results and Discussion: Like adults, children exposed to the coronavirus can be infected with it and display signs of Covid-19. At the beginning of the pandemic, it was assumed that children are not getting infected with the coronavirus, but now it is clear that the amount of infection in children is the same as in adults. It is just when they do get the infection they show much milder symptoms. However, young children, particularly infants were vulnerable to infection. Children frequently do not have a notable disease, raising the possibility for facilitators of viral infection transmission. Conclusion: From this review, we can conclude that children are also susceptible to COVID 19 on the exposure to the virus and they are not essentially immune to COVID-19.
