We proposed an algorithm for organizing and carrying out activities on control without interacting with legal entities and individual entrepreneurs in the course of state social and hygienic monitoring (SHM). Methodological approaches to the development of the Order of tasks' drawing up for carrying out these activities, the requirements for their content, as well as the drawing up the activities' results on control without interaction with legal entities and individual entrepreneurs in the course of SHM by specialists of the Federal Service for Surveillance of Consumer Rights Protection and Human Wellbeing were suggested.

The paper examined the issues of sequence (algorithm) of physician's activity on the hygiene of children and adolescents of the department for medical care organization for minors in educational institutions. We have formulated the methodical basis for the development of recommendations for the provision of primary health care to students (algorithms of the physician's activity on the hygiene of children and adolescents of the departments for medical care organization for minors) that will improve the efficiency and effectiveness of all concerned organizations activities in the field of hygiene and health of children and adolescents, ensuring sanitary and epidemiological wellbeing of younger generation.

We evaluated the physical fitness of 146 primary school students (68 boys and 78 girls) in the dynamics of the school year in order to substantiate the hygienic optimization of physical education organization based on a differentiated approach taking into account the sex of students. Results' analysis revealed that the age period of 8-9 years is a sensitive period for the development in children of speed, power, speed-strength and coordination body capabilities. It is shown that in order to increase the efficiency of physical education, it is advisable to conduct physical education classes differentially depending on the gender of the students.

The peculiarities of the forming the most common functional deviations and chronic diseases in students in the school ontogenesis dynamics are revealed. The morbidity dynamics of functional disorders and chronic diseases of the nervous system and mental sphere is presented. We analyzed changes in the prevalence of functional visual impairment and chronic diseases of the visual analyzer. The course of the pathological processes after the diagnosis of each student was evaluated according to the data of specially developed catamnesis questionnaires. We found a high level of functional disorders' occurrence frequency of the nervous system and mental sphere (together) in primary school students and the rapid growth rate of the indicator from the 8th to the 11th forms. Visual impairment is characterized by an increase in the prevalence and unfavorable course of pathological processes during the whole school ontogenesis. The revealed functions of deviation and chronic diseases testify to the negative role of excessive academic load of students, psycho-emotional and visual overstrain in the formation of pathological conditions in school students.

We analyzed the epidemiological situations on influenza and acute respiratory viral infections during the 2015-2016, 2016-2017 and 2017-2018 epidemic seasons in the Republic of Sakha (Yakutia). The 2015-2016 and 2016-2017 epidemic seasons differed from the previous ones by a rather high intensity of the epidemic process, moderate duration of the epidemic awareness with a two-wave pattern of the course, high morbidity of the population at the epidemic peak and the absence of the disease’s severe forms in those vaccinated against influenza. During the 2015-2016 epidemic season, the influenza A(H1N1) virus was the dominant pathogen in Yakutia. During the 2016-2017 epidemic season, the first morbidity awareness was caused by the influenza A(H3N2) virus, the second morbidity awareness was caused by the influenza B virus. In contrast to previous two seasons the 2017-2018 epidemic season is characterized by lower intensity, a significant morbidity decrease of influenza and acute respiratory viral infections in different age groups of the population and a low level of influenza viruses' circulation. Influenza A (H3N2) virus dominated and joined influenza B virus circulation was registered subsequently during the 2017-2018 epidemic season.

An analysis of the ecological and ethological characteristics of the domestic cat presented in the literature data shows that the wild ancestors of this animal that lived in the desert did not participate in the evolution of the parasitic system of the opisthorchiasis agent. Formation of complex life cycles of trematodes of the family Opisthorchidae in the Cenozoic era occurred with the participation of representatives of mammals'different systematic groups. The domestic cat on the territories of Eastern Europe and Western Siberia historically did not participate in the formation of the parasitic system Opisthorchis felineus, because it appeared in these territories much later, when the parasitic system of the agent existed there since the end of the Miocene. The main factors that determined the role of the domestic cat as the definitive host and the ecological stalemate of the opisthorchiasis agent were its interaction with the environment and the genetically determined animal's behavior.

In recent decades, there is an increase in the number of toxocariasis morbidity rate in many countries. An important role in the implementation of the infection's risk with toxocarosis is the state of contamination with pathogens of epidemiologically significant environmental objects. Toxocara eggs are resistant to adverse environmental factors and can persist in the soil for a long time. We presented data on seroepidemiological surveys for toxocarosis of the population of the South of Russia (Republic of Adygea, Karachay-Cherkessia; Astrakhan and Rostov regions, Krasnodar Krai) and results of soil sanitary-parasitological studies. The analysis of the population morbidity with toxocarcosis in the Russian Federation showed the variability of its indicators during different years. The basis for some territories zoning of the south of Russia for this helminth infection was formed with toxocarosis morbidity rates, the results of a seroepidemiological survey of the population, infection of dogs and soil contamination with toxocara eggs. According to the comparison of toxocariasis morbidity data with the results of seroepidemiological studies, we suggest that the true level of helminthiasis morbidity in the South of Russia is much higher than officially registered. The results of the studies indicate the need for caution in the aspect of the potential probability of population's toxocarosis infection.

We presented the results of measures taken by the Moscow Office of Rospotrebnadzor to ensure sanitary and epidemiological wellbeing during the preparation and hosting the 2018 FIFA World Cup (Championship): providing control at all construction stages of sports facilities and sports infrastructure, including laboratory and instrumental control of building, finishing materials and finished products. The surveys of all involved in the Championship facilities, as well as within adjacent areas to especially radiation-hazardous facilities in Moscow (National Research Center «Kurchatov Institute», National Research Nuclear University «Moscow Engineering Physics Institute», Institute for Theoretical and Experimental Physics named after A.I. Alikhanov of National Research Center «Kurchatov Institute», N.A. Dollezhal Research and Development Institute of Power Engineering) were conducted in terms of ensuring radiation safety. An examination of activities with sources of ionizing radiation was carried out; 21 sanitaryepidemiological conclusions and 6 licenses on compliance with the above activities were issued.

We presented the results of the work on environmental factors monitoring (ambient air, drinking water, soil, environmental conditions at sports facilities), evaluation of potential health risks during the preparation and hosting the mass events with international participation on the example of the XXI FIFA World Cup matches in Volgograd. A number of activities based on the obtained data were planned and implemented to ensure the sanitary and epidemiological wellbeing such as improving the quality of the city's air environment, providing drinking water that complied with all hygienic requirements.

We systemized the experience of the Rospotrebnadzor Office in the Voronezh Region in organization and carrying out the sanitary and hygienic and anti-epidemic (preventive) measures during the preparation and hosting the 2018 FIFA World Cup (Championship) to ensure sanitary and epidemiological wellbeing within its subordinate area. The priority directions of activity during the preparation and hosting the competitions period are determined. We showed and presented the results of the laboratory control for the environmental objects, monitoring during the Championship preparation and hosting period; the results of the surveillance activities regarding the potential risk objects; outreach on the infectious diseases' prevention.The issues of interdepartmental interaction with the territorial bodies of the federal executive bodies, the executive bodies of the Voronezh region during the preparation and hosting of the mass events are reflected. The paper presents an assessment of the epidemiological situation on the morbidity of infectious and parasitic diseases on the territory of Voronezh during the preparation and hosting the Championship. We showed the activity issues of the Rospotrebnadzor Office in Voronezh Region at checkpoints across the state border of the Russian Federation; immunization of people who were taking part in the events of the competitions. The issues of consumer rights protection on issues related to the Championship are briefly covered.

We summed up the work carried out by the Rospotrebnadzor Office in the Stavropol Krai and the Hygienic and Epidemiological Center in the Stavropol Krai during the preparation and hosting the 2018 FIFA World Cup events on the territory of the Stavropol Krai. The main activities were aimed at assessing and minimizing the sanitary and epidemiological risks in organizing accommodation, food, medical care for the arriving football team of Nigeria.
