The article is devoted to a review of scientific publications that describe the impact and long-term outcomes of COVID-19 on bronchial asthma (BA) in children. The COVID-19 pandemic has sparked debate in the scientific community. After the declaration of the COVID-19 pandemic many countries implemented public health measures aimed at limiting the spread of SARS-CoV-2, which also affected the prevalence of other respiratory viruses with similar transmission ways. It is known that during the period of COVID-19 the frequency of visits to the doctor of the children with BA has decreased significantly. A decrease in the level of hospitalizations due to exacerbation of BA in 2020-2022 was also determined. However, the results of studies by different authors regarding the relationship between BA and hospitalization among children with COVID-19 are controversial. The main reasons for reducing the frequency of asthma exacerbations and improving the control of the course of the disease during the period of COVID-19 are associated with a decrease allergens' influence, an increase in adherence to treatment, and a decrease in the risk of other respiratory viral infections. However, after the quarantine restrictions were lifted, an increased frequency of hospitalizations and deterioration of disease control due to an increased number of exacerbations of asthma was determined. The COVID-19 epidemic has been a significant stimulus for the development of telemedicine, but there is no substitute for person visits for physical examinations and certain tests that are critical in BA. The results of some studies did not show changes in external respiratory function data during the examination of children after COVID-19. However, changes in spirometry data and the need to change treatment were observed in some patients with asthma, indicating that SARS-CoV-2, like other respiratory viruses, may impair asthma control. To date, the long-term outcomes of COVID-19 in children and adolescents remain insufficiently studied and characterized. The current literature presents several compelling risk factors for the development of persistent COVID-19 in the pediatric population. Unfortunately, to date there is no clear data on the impact of SARS-CoV-2 on the course of BA in children. Therefore, further research into the long-term outcomes of the coronavirus infection in children with BA is critically important. [ABSTRACT FROM AUTHOR]

Bacterial, allergic, parasitic and fungal skin lesions are much more common among children than among adult patients. The aim of this study was to analyze data on the prevalence and incidence of diseases of skin and subcutaneous tissue with allergic and non-allergic origin among children of Ukraine in period from 1994 to 2017. Our main purpose was to determine the possible impact of different adverse environmental factors on children`s growth, including radiation, connected with the Chernobyl disaster in 1986. Over the past 24 years Ukraine has witnessed a 10.3% increase in prevalence of diseases of skin and subcutaneous tissue among children and 8.6% raise of incidence rate with a predominance of detection of this pathology in children affected by the Chernobyl accident and children from areas of radiological control. We have found a direct influence of moderate strength on the connection between population-weighted effective dose of total human exposure (in millizieverts) in different regions of the country in the period of 1997-2011 and the incidence and prevalence of skin diseases among children aged 0-14 years, including 2011 (p<0.05).This fact may indicate the impact of this disaster on the occurrence and pathogenesis of skin diseases and its consequences among children. During the same period, due to the influence of a number of environmental factors, there was a significant transformation in the structure of skin diseases in children. We have witnessed double increasing of the proportion of allergic lesions of the skin and its elements. The prevalence of diseases of the skin and its elements in general has reached 28.7% against the corresponding reduction of skin infections. [ABSTRACT FROM AUTHOR]
