COVID-19 coronavirus infection in children: Clinical presentation, diagnosis, vaccination, and treatment
https://doi.org/10.21508/1027-4065-2022-67-6-14-24
Abstract
In late 2019, a new subtype of coronavirus named Severe Acute Respiratory Syndrome Coronavirus 2 (COVID-19 SARS-CoV-2) rapidly spread around the world, causing a global pandemic. Initially, the proportion of confirmed cases among children was relatively small, and it was believed that children were rarely infected. Subsequent observations have shown that in children and adolescents, the infection is either asymptomatic or paucisymptomatic, and therefore the true incidence is underestimated due to the lack of testing. The article systematizes the results of studies on the prevalence, diagnosis, clinical features, vaccination, and treatment of children with a new coronavirus infection COVID-19 SARS-CoV-2. The SARS-CoV-2 positivity rate throughout the peak of the pandemic in children was low compared to adults. Children are not only less likely to become infected with the virus, but they also endure the infection more easily than adults. The mortality rate in children with COVID-19 was <0.5%. In most children, infection is either asymptomatic or paucisymptomatic. Vaccination of children and adolescents is recommended mainly to achieve herd immunity in all age groups. However, there are no convincing data on the duration of the immune response, the level of the required protective antibody titer, as well as on the long-term side effects of vaccination due to the insufficient follow-up period and the uncertainty of the immune response criteria. As information is accumulated on the viral load of children and adolescents, their role in the transmission of the virus, diagnostic approaches in this age group are optimized. The effectiveness of the treatment was tested on patients admitted to the hospital, and recommendations for treatment were developed. Currently, global research efforts are focused on the protection of particularly vulnerable children, the prospects for total childhood vaccination, its effectiveness and safety.
