Prevention of acute enteric infections and viral hepatitis A in the Krasnodar Territory appearing in connection with a natural disaster in 2002

Materials on the sanitary and epidemiological situation in the Krasnodar Territory in connection with emergency situations (intensive snowfalls, heavy showers, high floods) in 2002 are presented. The scope of the destruction of the systems ensuring the life provision of the population in the affected regions of the territory is shown. To carry out the epidemiological surveillance on acute enteric infections, to make corrections of the planned prophylactic measures, as well as the timely solutions of problems connected with controlling the epidemiological situation, the daily monitoring of the level and dynamics of infectious morbidity in individual settlements among different age and professional groups, as well as the foci of infections, was established. 65 cases of acute enteric infection and 4 cases of viral hepatitis A were registered in the affected areas, which did not exceed the average morbidity figures for many years. A complex of sanitary, hygienic and prophylactic measures was carried out by the sanitary and epidemiological service of the territory, which made it possible to maintain human morbidity in acute enteric infections and viral hepatitis A in the affected areas on the sporadic level.     

Basic measures for prevention of the epidemiological consequences of a natural disaster in the North Caucasus in 2002

The system of organizational and prophylactic measures, carried out with a view to prevent epidemiological aggravations in connection with the natural calamity in the Southern Federal District of the Russian Federation in 2003, is described. Proposals on the improvement of the system of preventive measures, including the monitoring of the epidemiological, sanitary and hygienic situation, personnel training, technical provision, the cooperation of different services and departments, capable of ensuring the liquidation of the consequences of emergency situations of the natural character, are made.

Materials on the organizational provision and financing of measures taken with a view to ensure the sanitary and epidemiological safety in the Stavropol Territory in connection with the high flood of 2002 are presented. Due to the joint efforts of sanitary, antiepidemic and medico-prophylactic services of the Territory, administrative organs and institutions, as well as other relevant departments, not only high quality restoration works were carried out and completed in a short time, medical assistance was given to the victims and the appearance of mass infectious diseases prevented, but also the growth social tensions in the affected areas was averted.     

Epidemiologic situation of brucellosis in the regions of the Republic of Dagestan affected by the flood of 2002

The Republic of Daghestan is at present one of the most unsafe territories in the Russian Federation with respect to brucellosis morbidity among humans. The figures of human morbidity in brucellosis grew from 3.4 per 100,000 of the population in 1999 to 10.5 per 100,000 of the population in 2002, thus exceeding the figures for the whole of Russia 15- to 20-fold. The analysis of human morbidity in the Kizlyar region (where the interregional regrouping of the cattle was made) after the natural calamity, as well a in other regions where live-stock was evacuated, indicated that by the end of 2002 an essential deterioration of the epidemiological situation took place in these regions. In view of grave epizootological situation and the absence of epidemiological safety in brucellosis in the Republic of Daghestan the sanitary, epidemiological and veterinary services should, together with other priority tasks in their work aimed at the liquidation of the emergency situation, pay greater attention to measures for the prevention of the spread of brucellosis.     

Emergency situations in the Republic of Ingushetia and the prevention of their epidemiological consequences

Information on the sanitary and epidemiological situation and water supply in the Republic of Ingushetia during the period before and after the emergency situation (high flood) is presented. The results of epidemiological observations on the territory of the Republic of Ingushetia for the period of June 22 to the end of the year 2002 indicate that no considerable rise in infectious morbidity, as well as outbreaks of natural focal infections, was noted. This suggests that, in spite of the complicated sanitary and epidemiological situation before the emergency situation (due to the vicinity of the conflict in the Chechen Republic, the intensive migration of the population and the presence of a large of refugees on the territory of the Republic of Ingushetia) and its sharp deterioration caused by the high flood, the timely realization of a complex of sanitary and prophylactic measures made it possible to avoid the wide spread of infectious diseases.     

Prevention of acute enteric infections and viral hepatitis A in the Republic of Dagestan in connection with the flood of 2002

The data on the sanitary and epidemiological situation in the Republic of Daghestan during the period of high flood in 2002. The scope of sanitary, hygienic and prophylactic measures carried out during this period with a view to prevent the appearance of the outbreaks of acute enteric infections and viral hepatitis A in the Republic of Daghestan is shown.     

Prevention of acute intestinal infections based on the epidemiological surveillance system

The development of the system of epidemiological surveillance and its introduction into the practical work of the district sanitary and epidemiological station made it possible to decrease morbidity in acute intestinal infections 2.4 times in comparison with preceding years, as well as to put an end to the outbreaks of these infections. The work proved the advantage of epidemiological diagnosis permitting the introduction of measures which prevent the formation of the epidemic strain of the infective agent and thus affect the seasonal rise of morbidity.     

Epidemiologic situation in the quarantine of natural focal infections in the Southern Federal District

Materials on the situation in quarantine natural focal infections (anthrax, plague, tularemia, brucellosis, leptospirosis, etc.) in the Southern Federal District are presented. Experience in the provision of the epidemic safety in the above-mentioned diseases, based on the systematic surveillance on the activity of epizootological factors on the territory of the natural foci of infections, are described. The causes of the possible aggravation of the epidemiological situation in a number of nosological forms in connection with changes in natural and socio-economic factors are given. The results of the realization of regional programs, making it possible to improve the system interaction between the administrative territories, services and departments aimed at ensuring the epidemiological safety of the region, are shown.     

An analysis of the seasonal rise in hepatitis A morbidity at a children's center and ways to improve the sanitary epidemiologic surveillance for this infection among organized preschoolers

The spread of hepatitis A in children's institution occurred through everyday contacts, the boundaries of the focus of infection embraced the whole institution, and the active detection of the prevailing subclinical forms of the disease proved to be possible by means of virological and biomedical tests. The enhancement of the effectiveness of clinical and epidemiological surveillance by its orientation to the control of the spread of this infection through water and everyday contacts, the rational organization of sanitary, microbiological and serological studies, the development of criteria of epidemiological safety of children's institutions is proposed.     

Sanitary and epidemiological provision of the personnel of the units and border formations of the North Caucasus Regional Command of the Border Guard Service of the Russian Federation

The factors affecting the environment of servicemen doing their duties in connection with the task of guarding the state frontier of the Russian Federation are presented. The main trends in the activity of the sanitary and epidemiological service, carried out under regular conditions and the period of the liquidation of the consequences of high floods in the Southern Federal District in 2002 with the aim of preventing the aggravation of the epidemical situation, were shown to be determined, and the corresponding measures taken, in due time, thus making it possible to prevent the growth of morbidity in enteric and other infections among the personnel of the units and formations of the North Caucasian Regional Command of the Federal Frontier-Guard Service of the Russian Federation.     

On the epidemiological situation in quarantine, natural focal and other infections on the territory of the Southern Federal District

The data on the sanitary and epidemiological situation in the Southern Federal District are presented. The analysis of morbidity in tuberculosis, measles, HIV infection, viral hepatitis A, typhoid fever, cholera and quarantine infections, Crimean hemorrhagic fever, West Nile fever, rabies, malaria has been carried out. Special attention has been given to "new and newly returning infections", and among them to the spread of SARS ("atypical pneumonia"). The role of regional epidemiological safety programs, in particular such program as "The prophylaxis of quarantine and natural focal infections and the sanitary protection of the territory of the Southern Federal District of the Russian Federation from the import and spread infectious diseases in 2003-2005", has been substantiated.     

Bacteriological provision of anti-epidemic measures in the zones of a natural disaster in Southern Russia in 2002

The bacteriological provision of the prophylactic and anti-epidemic measures, taken under the conditions of the unstable sanitary and epidemiological situation which arose as the result of the emergency situation due to the high flood in the Southern Federal District, was carried out by the efforts and means of microbiological laboratories forming a part of the territorial system of observation and laboratory control. On the whole, more than 20,000 samples of water supplied to the population for drinking and household use, more than 10,000 samples of foodstuffs and cooking raw materials were examined in the Southern Federal District during the period of the liquidation of the medico-sanitary consequences of the emergency situation (June-August). To study the epidemic potential of the natural foci of quarantine infections and the probability of the spread of Bacillus anthracis from burial grounds for sick animals, the laboratory capacities of plague-control institutions were used.     

Hospital infections: the problems and ways to resolve them]

The authors present the critical analysis of the existing situation in the spread of purulent septic infections in surgical hospitals of the USSR and the state of epidemiological surveillance. Considering this situation to be highly unfavorable, the authors propose a number of urgent organizational measures (the inclusion of hospital epidemiologists into the medical staff of large clinics, the system of training in this problem). The article deals with the specific features of the epidemiological process in purulent septic infections and the main principles of the organization of the epidemiological surveillance system for this group of infections.     

An epidemiological analysis of postoperative suppurative pathology in surgical hospitals]

Approaches to the epidemiological analysis of postoperative wound complications in surgical hospitals are summarized. The indices for the evaluation of the epidemic situation in surgical departments (the ratio of severe and mild forms of complications, severe and posthospital complications) are proposed. To determine the site of infection, the method of graphic analysis, involving the fixation of dates of the operation and the appearance of the complication and taking into account regularities in the development of the outbreak, the depth and severity of the lesion, is proposed. Epidemiological surveillance at medical institutions permits the prognostication of the epidemiological situation. The realization of epidemiological surveillance at the level of individual medical institutions is the prerequisite of effective functioning of the program of epidemiological surveillance at a given territory.     

Epidemiological situation on tularemia in the regions of Stavropol Territory affected by flood

The data obtained in the analysis of the epidemiological situation in tularemia in the zone of inundation in the Stavropol Territory in 2002 are presented. The current systematic epidemiological surveillance, as well as the data of urgent epizootological and epidemiological survey in the zone of inundation permitted the objective prognostication of the situation in tularemia and formed the basis for the rational planning and realization of prophylactic measures.     

Prevention of acute enteric infections and viral hepatitis A in the Stavropol Territory in connection with a natural disaster

Materials on the organization and realization of prophylactic measures with respect to acute enteric infections (AEI) and viral hepatitis A (VHA) at the period of the liquidation of medico-sanitary consequences of the high flood are presented. As shown in these materials, the epidemiological surveillance on AEI and VHA in the areas affected by the emergency situation included the effective system of monitoring on these diseases. On the basis of monitoring optimum decisions were taken and concrete prophylactic measures were realized. This made it possible to detect the foci of infectious diseases in due time and efficiently liquidate them, as well as to prevent the development of the epidemiological consequences of the high flood.
