ABSTRACT
At present, there are isolated data on the clinical outcomes of COVID-19 in children, especially those who have experienced asymptomatic and mild forms of infection. Purpose(s): to analyze the nature and frequency of post-COVID symptoms in children during 12 months. after recovery. Materials and methods. The influence of demographic indicators, premorbid background, severity of infection and therapy in the acute period of the disease on the nature and frequency of symptoms in 1079 children who underwent laboratory-confirmed COVID-19 was studied. The results are presented with proportions (%) and calculation of 95% confidence interval according to Klopper-Pearson. Differences between groups were assessed using Pearson's chi-square test. Differences in the groups were considered statistically significant at p < 0,05. Results. Health disorders in the post-COVID period were observed in 8,5% of children, more often in schoolchildren aged 7-17 years (68.4%). Concomitant conditions were found in 38,0%. In most cases, the consequences were noted after a mild form of COVID-19 (77.2%), however, 13,0% of patients experienced an asymptomatic form of infection. Among convalescents, changes in the emotional sphere (2,1%), headache (1,8%), symptoms of asthenia (1,6%), cardiovascular (1,5%), dyspeptic (1,3%) were more often observed, cognitive (1,3%) disorders, neurotic disorders (1,0%), less often respiratory (0.8%), endocrine (0,4%) and visual (0,4%) systems, musculoskeletal system were involved (0.2%). Girls were significantly more likely to have vegetative disorders, while boys were significantly more likely to suffer from cognitive functions. Various antiviral therapy options (interferon-alpha, an oral antiviral drug, or a combination thereof) in the acute period of COVID-19 did not affect the possibility of post-COVID disorders, but there was a tendency to increase the frequency in children who did not receive etiotropic treatment (control group). In 14.1% of cases, post-COVID symptoms appeared late - after 5-10 months. after recovery. The course of rehabilitation therapy, including drug treatment and non-drug methods, made it possible to quickly restore the state of health of the observed children. Conclusion. In most cases, the violations were of a functional nature, due to a disorder of autonomic regulation. Rehabilitation and dispensary observation programs will allow timely restoration of the quality of life of children who have had COVID-19, including in a mild and asymptomatic form.Copyright © 2022 Authors.

ABSTRACT
Background. The use of antiviral agents can shorten the duration of the viral infection. The aim: to study the clinical and epidemiological features and the effectiveness of antiviral therapy for new coronavirus infection (COVID-19) in outpatient children. Materials and methods. From April 2020 to March 2021, 9334 outpatient children aged from 0 months to 17 years were randomly tested for new coronavirus infection. SARS-CoV-2 RNA was detected in oropharyngeal and nasal material by PCR. Patients with confirmed new coronavirus infection were prescribed interferon-alpha (IFN-a) intranasally, antiviral agents of systemic action. The control group consisted of children with COVID-19 who did not receive treatment. Results. When examining clinically healthy contact children, SARS-CoV-2 RNA was detected in 7.4 % of cases. In the structure of ARI, the specific weight of COVID-19 was 12.3 % with the peak incidence in April-May (up to 22.8 %) and November- December (up to 30.0 %). In half of the cases, children became infected in the family, and usually adults were the index patient. In 47.7 % of cases, an asymptomatic form of COVID-19 was registered without significant differences in patients of different ages. In one third of children with concomitant pathology, the disease was asymptomatic, in half it was mild, in other cases moderate severity was diagnosed. The clinical picture of COVID-19 did not differ from other ARIs. Anosmia (9.4 %) in half of the cases was combined with ageusia (4.4 %) and was significantly more common in boys. The duration of clinical manifestations in children of the control group and those who received antiviral therapy did not statistically significantly differ in mild and severity of the disease. Also, various antiviral therapy options did not significantly affect the duration of SARS-CoV-2 detection in children with various forms of COVID-19. Conclusion. In the first year of the pandemic, the novel coronavirus infection did not dominate the pattern of respiratory diseases in outpatient children. Further research is required to develop pediatric guidelines for the treatment of COVID-19 at the outpatient stage. © 2021 Scientific Centre for Family Health and Human Reproduction Problems.

ABSTRACT
The new coronavirus infection (COVID-19) is a socially significant problem around the world. According to available statistics, complications are less common among children, asymptomatic or mild forms of the disease prevail more often. This article presents the features of the viral landscape of the upper respiratory tract in children with ARVI in a pandemic, the clinical and laboratory features of the course of COVID-19 in children of different ages. It was found that SARS-CoV-2 is detected only in a third (32.9%) of hospitalized patients with respiratory symptoms, in 4.3% of cases - in combination with seasonal CoV-OC43 / CoV-229E, in 11.6% - with other respiratory viruses. The most frequent source of infection with the SARS-Cov-2 were family members. Children with a moderate form of the disease predominated among the patients. The leading symptoms of COVID-19 were fever, catarrhal symptoms, as well as gastrointestinal manifestations and anosmia. A feature of the new coronavirus infection in newborns and children of the first month of life was the absence of fever and intoxication, the lack of expression of catarrhal manifestations when the colon is involved in the pathological process (colitis, rarely - hemocolitis). In the compete blood test in children under the age of one year, monocytosis prevailed, in children over 7 years old - leukopenia and accelerated ESR. Among the changes in the biochemical analysis of blood, the most common was an increased C-reactive protein.
ABSTRACT
In the Russian Federation, the proportion of children among all cases of new coronavirus infection is up to 8.6%. Mild forms are registered in 80% of cases, severe – 0.2%, as a rule, in children of the first year of life. The majority of deaths were recorded in children with an unfavorable background:75% of those who died had one concomitant pathology, 45% – two or more. The problem of severe course and fatal outcomes from COVID-19 in children with comorbid pathology, for example, with various forms of leukemia, remains relevant. Severe infectious complications of bacterial nature are observed in 70–80% of sick children, viral and fungal genesis, respectively, in 4–12% and 18–20%. Myeloblastic leukemia is one of the factors that predispose to a severe course of COVID-19 and an unfavorable outcome. The article presents a clinical observation of the course of a critical form of a new coronavirus infection in a young child with acute myeloblastic leukemia. The layering of COVID-19 contributed to a sharp deterioration of the underlying disease. Despite the highly organized treatment process with the use of modern technologies, the child had a rapid deterioration of the condition with a fatal outcome. © 2021, Dynasty Publishing House.
