Relevance. Spreading of the COVID-19 epidemic highlighted a number of new challenges related to protecting the health of first-line emergency and specialized medical personnel, as the high incidence of COVID-19 among healthcare workers can lead to risks of health system collapse. At the same time, in the interests of personnel safety, robotic technologies can be applied for heavy and dangerous works of air disinfection in enclosed medical environments.Intention: To present current views on robotic air disinfection of enclosed medical environments based on the analysis of robot prototypes developed to counteract the spread of the SARS-CoV-2 virus.Methodology. Analysis of tasks related to maintaining a safe working environment for healthcare professionals was based on the description of the functionality and specifications of robots designed to decontaminate the working environment of medical personnel deployment. When systematizing solutions for robot design, the main criteria used were the selection of control modes (Automatic, Supervisory, Manual and their combinations), hardware for disinfection in the external environment and in premises, and features of Human-Machine interaction for the safety of robotic support in enclosed medical premises.Results and Discussion. The features of using service (disinfection) robots are formulated based on epidemiological knowledge of the primary transmission routes and methods of disinfection of premises. It is shown that the tactical and technical characteristics of existing models of Autonomous mobile robots are mainly aimed at implementing unmanned technologies. Solving problems of massive processing of objects of the external environment, as well as vast areas of airports, stadiums, hypermarkets, warehouses, vehicles in a reasonable time involves automatic modes and/or Supervisory control of such robots by the operator in remote mode. The use of disinfection robots in enclosed medical premises requires additional consideration of the factor of introducing robots into the social environment. From these positions and on the basis of the selected prototypes, the prospects are considered for using a group of small mobile robots equipped with systems that enhance sensory and communication capabilities in the work environment.Conclusion. Using robots to reduce risks of the SARS-CoV-2 contamination opens the way to improving the working conditions of healthcare professionals who are at risk of COVID-19. The proposed methods of robotic disinfection of medical premises also help reduce the mental strain of being in a dangerous environment by expanding robotic support for decontamination of premises and flexible response to changes in the environment

Relevance In the context of the new coronavirus infection (COVID-19) pandemic, research on the formation of an immune response to SARS-CoV-2 in patients with various clinical forms of this infection is of particular relevance, which is important for understanding the degree of their participation in the formation of population immunity and assessing individual immunity to SARS-CoV-2 in the future. Aim of the study was to analyze the timing of the formation of specific antibodies to SARS-CoV-2 and the duration of their preservation in patients with a new coronavirus infection. Materials and methods. The timing of the formation of specific antibodies of three classes (IgA, IgM and IgG) to SARS-CoV-2 in 218 patients was evaluated in the first days of the disease. Subsequently, they were re-examined at various times from the onset of the disease, from one to four times (a total of 321 control points). To assess the duration of preservation of antibodies to COVID-19 in patients who were ill, a prospective study was organized, in which 368 people participated. Screening for specific class G antibodies was performed every 2–4 weeks, within one to eight months of the onset of clinical manifestations of COVID-19. In total 919 control points. The antibodies were examined by solid-phase enzyme immunoassay using the SARS-CoV-2IgM-ELISA-BEST and SARS-CoV-2-IgG-ELISA-BEST test systems (manufactured by VECTOR-BEST JSC) and Antigma A (manufactured by Generium). Results. In most of the examined individuals, class M and G antibodies began to form from day 10 of the disease, while class A antibodies were detected from day 5. In mild and asymptomatic forms of coronavirus infection, IgG antibodies to SARS-CoV-2 were not formed in most cases, and seroprotection levels correlated with the severity of the disease. The duration of preservation of IgG antibodies could be at least 8 months, but there were isolated cases of their elimination both after COVID-19 in the form of respiratory infection and after interstitial pneumonia. With continuing problems with COVID-19, there were no cases of recurrent disease among individuals who formed G-antibodies (including those who lost them 4-5 months after the disease) during the follow-up period. Conclusion. Thus, according to the results of the study, important materials were obtained on the peculiarities of the formation of a humoral immune response to a new coronavirus infection. However, to fully understand the immune response to SARS-CoV-2, it is necessary to assess the avidity of IgG antibodies or their ability to neutralizing the virus, as well as to study cellular immunity in patients who have had COVID-19 but have not formed antibodies.

Rationale: The emerging new coronavirus infection caused by SARS-CoV-2 has resulted in a pandemic. Its clinical manifestations are highly variable and the death rate is high due to rapid progression to acute respiratory distress syndrome. Identified abnormalities of the eye are mainly related to conjunctival injury during manifestation of the disease.Aim: To study the eye abnormalities in patients who have undergone COVID-19.Materials and methods: Ophthalmological examination was performed in 23 patients (6 [26%] men and 17 [74%] women, median age 42.39 years) at days 44 to 85 after manifestation of COVID-19 infection in the Department of Ophthalmology, MONIKI. In addition to the standard ophthalmological examination, all patients were evaluated with optical coherence tomography (OCT), auto fluorescence, contrast and color sensitivity test with different light sources, and tear production assessment.Results: In the late convalescence period there were complaints of dry eyes and abnormal color perception, with visual acuity being unchanged. The OCT assessment the peripapillary retina identified small hyper-reflective foci in the inner layers.Conclusion: Eye disease in patients after COVID-19 is mainly related to the condition of the eye surface, abnormal color perception and abnormal architectonics of the inner retinal layers, which can persist for a long time during convalescence.
