The data on diphtheria morbidity and the occurrence of carrier state for its causative agent at the period of 2001-2002 were analyzed. The rates of morbidity and detected carrier state for these years were 0.63-0.55 and 0.65-0.64 respectively. Nevertheless, in spite of the relatively low morbidity rates the presence of the toxic forms of diphtheria (400 patients for two years) and lethal cases (with lethality rate reaching 5.4%) indicated that the epidemic situation in diphtheria remained tense. The most unfavorable situation was observed in the North-Western and Central regions of Russia. In urban areas morbidity rates were still 2- to 3-fold higher in than in rural ones, but the latter showed a higher percentage of severe cases (46.6% in 2001 and 39.7% in 2002) and lethal outcomes (13.6% and 19.2%). The latter was indicative of drawbacks in the immunoprophylaxis, diagnostics and treatment of diphtheria in rural areas. In the total structure of diphtheria patients adults prevailed: 75%. The highest morbidity rates were registered among children aged 3-6 years, among adults in the age groups of 18-19 years and 50-59 years. The epidemic process developed mainly among the immunized population, which was indicated by a high proportion of vaccinated persons among those affected by this infection (62.8-66.6%) and a mild course of the disease in the majority of them. The present epidemiological situation in diphtheria was determined by patients not vaccinated against this infection. The proportion of severe cases among nonvaccinated children was 42.4-51.6% and lethal outcomes, 12.9-15.1%. Among nonimmunized adults these figures were equal to 43.1% and 9.3% respectively. The highest percentage of children, not vaccinated during the first years of their life, was registered among those in the asocial families, refugees and homeless persons. Among adults these were persons above 50 years old, as well as jobless persons of working age, pensioners and invalids, who had limited possibilities of undergoing vaccination due to their social position. It was these social and age groups that should be regarded as risk groups with respect to the severity of the course of diphtheria and lethality. To stabilize diphtheria morbidity, the full complex of prophylactic and antiepidemic measures, and primarily the immunization of the population, should be systematically carried out. 相似文献

The results of the analysis of the present epidemiological situation in diphtheria in the Maritime Territory are presented. The data on absolute and intensive characteristics, death rate due to this infection, the vaccination status of diphtheria patients, as well as the results of the study of the level and intensity of antidiphtheria immunity in the healthy population of the territory. The study revealed that the defects of collective antidiphtheria immunity correlated with morbidity rate among adults and children. Adults aged 40-50 years and children aged 6-7 years were regarded as risk groups; among them the highest proportion of nonimmune persons and the highest diphtheria morbidity rate were registered. Stabilization achieved by the present moment was the result of the mass immunization of the adult population, ensuring the necessary coverage (92%) of vaccination in 1995. 相似文献

The article deals with the state of immunity to diphtheria and tetanus among the adult population in some administrative regions of the RSFSR. Of the children and adults covered by the survey, 91.3-96.7% were found to have protective antibody titers against diphtheria and 98.7-100%, against tetanus. An essential drop in the level of immunity to diphtheria in persons over 18 years of age was revealed: 71.7% of them were nonimmune, which correlated with the high morbidity rate among these persons. At the same time the percentage of adults nonimmune to tetanus was considerably lower than that of adults nonimmune to diphtheria, reaching only 27.1%. The state of immunity to tetanus in adults was found to depend on the seasons. 相似文献

In this work the characterization of the epidemic process of diphtheria infection on the territory of the RSFSR under the conditions of epidemiological surveillance (1983-1986) is presented. In comparison with the period of 1979-1982, an increase in morbidity rate occurred, which accounts for more complete detection of patients with mild forms of diphtheria, including persons found to be carriers of toxigenic Corynebacterium diphtheriae. Beginning from 1983, the leveling out of seasonal morbidity rises is observed. In the total number of persons affected by this infection the prevalence of adults is noted. Among them, a decrease in the morbidity rate was registered in 1986 (the maximum decrease was observed in age and professional groups of risk), which confirms the effectiveness of measures carried out for the protection of the adult population from diphtheria. Among children, a tendency towards a decrease in morbidity rate was noted in all age groups. The existing system of epidemiological surveillance on the territory of the RSFSR is capable of stabilizing diphtheria morbidity on a sporadic level and minimizing the number of fatal outcomes. The intensification of the epidemic process in some areas of the RSFSR is due to shortcomings in the realization of different measures of epidemiological surveillance. 相似文献

Observations on the stratum immune to diphtheria among the population, carried out over a period of many years and involving more than 37,000 people, have shown its gradual decrease in all adult age groups. In recent years the number of adults susceptible to diphtheria exceeded the number of susceptible children by 10.6%, and in some age groups by 18.5-21.8%, which makes for the total increase of diphtheria morbidity in recent years owing to its rise among adults. Regular revaccination of the adult population against diphtheria, made simultaneously with that against tetanus, is recommended. 相似文献

Immunization of children aged 3-6 years in kindergartens and school children aged 7-17 years against influenza with inactivated influenza vaccine was carried out in two districts of the Moscow region. The comparison of morbidity in influenza-like diseases among the immunized children with that among nonimmunized children in control districts revealed that the effectiveness of immunization was 60.9% in kindergartens and 68.8% in schools. The analysis of morbidity in a number of diseases among 158,451 elderly persons not immunized against influenza demonstrated that, in comparison with the control districts, in those districts where mass immunization of children was carried out morbidity in influenza-like diseases among elderly persons was 3.4 times lower and, out of other 10 diseases under study, morbidity in 8 diseases was 1.5-2.6 times lower. As indicated by the data obtained in this study, total anti-influenza immunization of children in organized groups not only essentially decreased influenza morbidity among children, but also greatly decreased morbidity in influenza and a number of diseases, appearing as complications of influenza infection, among nonimmunized elderly persons during influenza epidemic. 相似文献

Pregnant and parturient women have been examined in different regions of the USSR: Moscow, the Turkmen SSR, the Azerbaijan SSR and the Uzbek SSR. Altogether 720 placental sera and 522 funic sera have been checked for the presence of antibodies to diphtheria and tetanus toxoids in the passive hemagglutination test. Considerable groups of women with the insufficient level of immunity to diphtheria (40-66%) and tetanus (42.1-58.8%) have been revealed in different republics. Among women over 70 years the percentage of persons with the absence of antibodies or having low antibody titers has proved to be even higher. The comparative analysis of antibody titers has shown a correlation between antibody titers in mothers and newborn infants in 83.6% of cases for diphtheria toxoid and in 72.9% of cases for tetanus toxoid. These data show that among parturient women and newborn infants large groups remain unprotected against diphtheria and tetanus, which indicates the necessity of correcting the immune status of women of the productive age. 相似文献

The work defines the characteristic epidemiological features of diphtheria in the RSFSR at the present moment when a high level of antitoxic immunity is generally determined in children. With the diphtheria morbidity level having, on the whole, a sporadic character in the RSFSR, the intensification of the epidemic process has been found to occur in some regions. Changes in the ratio of morbidity rates among the urban and rural population are observed, the morbidity rate among the latter have the tendency towards increase. At present the characteristic feature of diphtheria is the prevalence of adults in the general morbidity structure. An important fact is a permanently high level of toxigenicity in Corynebacterium diphtheriae. As before, autumn is the season of the highest morbidity level. 相似文献

Official annual statistical data on morbidity in acute viral hepatitides (AVH), including the number of lethal cases, for 1985-1995 were analyzed. Mortality rates per 100,000 of the population at the period of 11 years were calculated for different age groups, sex and the place of residence. 396 and 99 patients were examined for the presence of serological markers of hepatitides A, B and E, respectively, at the periods of epidemic rises in morbidity and satisfactory epidemic situation. In the course of 11 years AVH caused the death of 22,405 persons. In 1985-1987 the average mortality level (ML) reached 12.3-17.8 per 100,000 of the population (with morbidity being 1,200-1,400 and was essentially higher among the rural population in comparison with the urban population. During these years the highest ML, was registered among children aged 0-2 years (190-50 per 100,000) and, among adults, mainly among women aged 20-29 years (21.4-19.6 per 100,000). During the years when the epidemic of AVH was absent, ML among these groups was essentially lower: 40-20 among children aged 0-2 years and 4-5 among women aged 20-29 years. In 1987 in the Fergana Valley hepatitis E was detected in 72.2% of all examined patients, and in the southern areas of the country in 68.7%. A sharp rise on mortality among women of the productive age at the period of the epidemic rise of AVH morbidity in the endemic region indicated that this epidemic was linked with hepatitis E. High ML among young children may be indicative of a highly unfavorable course of hepatitis E in the group of infants, which had never been registered before. This newly established regularity may be used for the retrospective diagnostics of the outbreak of hepatitis E. 相似文献

To solve the problem of unfavorable sanitary and epidemiological situation in diseases of respiratory organs in one of the organized groups in the Moscow region, a preparation prepared from a group of curative vaccines, IRS 19, was used. For controlling the effectiveness of its prophylactic action two groups of 250 persons were formed. As a result, morbidity rate in respiratory diseases decreased 2.5-3 times. In 1.5 months after the use of the preparation was started the coefficient of protection against the whole group of diseases of respiratory organs was 70%. 相似文献

The analysis of the dynamics of the epidemic process for 10 years made it possible to find out the presence of two separate epidemic waves of HIV infection. The first wave (1987-1994) was manifested as the slow type of the development of the epidemic, characterized mainly by sexual transmission. During this period 398 persons with HIV infection were detected, 24 persons were found to have AIDS; of these, 13 persons died. The second epidemic wave began in 1995 and was due to the spread of HIV among users of drugs introduced by injection. By the end of 1995 the number of HIV carriers was 34 times greater than that of 1994, reaching 1490 persons. In 1996-1997 this figure increased 8 times (annually). The number of AIDS patients rose to 420 persons. The most unfavorable regions with respect to HIV infection and AIDS morbidity were determined. The western regions of the Ukraine were noted to be in a more favorable situation in this respect with infection indices being lower more than 30 times. Up to 80% of all infected persons were found to be addicts introducing drugs intravenously. Growing morbidity in sexually transmitted disease, particularly in syphilis, contributed to the deterioration of the epidemiological situation. The conclusion was made on the necessity of introducing new prophylactic programs and expanding current ones. The signs of stabilization in Odessa and Nikolayev were observed; in these cities pilot programs aimed at the strategy of the "decrease of harm" have been introduced (in collaboration with UNAIDS) since 1996. 相似文献

Certain specific features of the present epidemic situation with hepatitis B (HB) in Russia were established: significant growth of HB morbidity, starting from 1995; the prevalence of persons aged 15-29 years among HB patients, which was linked with the sharp activation of the sexual route of the transmission of HB virus in recent years; an essential increase in the number of patients having contacted this virus in the process of the intravenous use of drugs. The results of the use of vaccine "Engerix B" among persons belonging to different risk groups were considered (a decrease in HB morbidity among them by 8-19 times was noted), the study demonstrated high immunogenicity anti-HBs antibodies on protective titers were determined in 92.3-95.7% of the vaccinees) and low reactogenicity of the vaccine, as well as stable postvaccinal immunity (5 years after the course of vaccination was completed anti-HBs antibodies were retained in 70.6-74% of the vaccinees). The study showed that only the vaccination of adolescents in combination, in the presence of opportunity, with the immunization of newborn infants and young children in the first year of their life made it possible to produce an essential effect on the activity of the epidemic process. Already in 2 years such organization of work on the prophylaxis of HB in one of the cities of the Sverdlovsk region led to a decrease in HB morbidity by 2.9 times, and among adolescents 9 times. 相似文献

The introduction of mass immunization against tetanus has resulted in the decrease of morbidity rate (5.2 times), the leveling of morbidity rate among the urban and rural population and among males and females, though no essential effect on the seasonal distribution of tetanus morbidity has been observed. Persons over 50 years of age (housewives and pensioners) have become the main groups of risk at the post-immunization period. Mass immunization against tetanus over a period of many years has ensured the existence of a sufficient immune stratum (89.9 +/- 3.0% to 100 +/- 3.0%) and a sufficient level of antitoxic immunity (means geom equal to 6.72-9.6 I.U./ml) among children. Among adults, the proportion of persons protected from tetanus decreases in older age groups from 82.1 +/- 1.3% in persons aged 31-40 years to 22.1 +/- 2.0% in persons over 60 years. The observed differences between the coverage of the population with immunization and the proportion of persons having protective titers of tetanus antibodies require constant control of the intensity of immunity and its correction with regard to its initial level, especially in persons of older age groups. 相似文献

The present epidemiological situation in diphtheria in the Republic of North Ossetia (Alania) is analyzed. The data on diphtheria morbidity and lethality are given. The present stable situation resulted from mass immunization of the adult population which ensured the level of vaccination coverage reaching 87% in 1995. 相似文献

This work, based on the retrospective analysis of shigellosis morbidity among organized groups of adults, as well as the whole population of the city, demonstrates the manifestations of the epidemic process. Water supply was common in the city, while water consumption was autonomous. The organized groups of adults did not use the products of the local milk-processing factory. The following facts were established. The dynamics of morbidity in Flexner's dysentery showed the change of dominating variants of the infective agent, which reflected the action of internal mechanisms of the development of the epidemic process. The role of Sonne dysentery in the total structure of shigellosis morbidity did not correlate with the consumption of milk and milk products. The theory of the self-regulation of the parasitic system and the theory of correspondence served as the basis for the theoretical interpretation of the manifestations of the epidemic process of Shigella infections. To ascertain the real correspondence of individual Shigella species to concrete transmission factors, further investigation are necessary. 相似文献

The cyclic nature of the epidemic process in Bulgaria was studied by various methods (spectral analysis, etc.), forming a system. The morbidity dynamics in 10 infectious diseases (scarlet fever, rubella, measles, epidemic parotitis, whooping cough, diphtheria, typhoid fever, enterocolitis, bacterial dysentery, viral hepatitis) over the years of 1909-1983 were studied and cycles covering the periods of 3-4, 5-6, 10-11 and over 16 years were established. The data on the relative part of cyclic processes in the registered morbidity of infectious diseases, as well as information on the prognostication of the spread of infections in the absence of vaccinal prophylaxis, are presented. 相似文献

To find out the epidemiological role of the carriers of hyaluronidase-positive meningococcal strains, their spread in the foci of meningococcal infection, as well as outside these foci, was studied. For this purpose, altogether 5059 persons from 40 family foci of infection and 40 organized groups were examined. The number of carriers of hyaluronidase-active meningococci, detected among those of them who had contacts with sick persons, was 13 times greater than among the persons having no such contacts. In preschool institutions with unfavorable morbidity situation this number was 16 times greater than in those with favorable situation. In the family foci carriers of hyaluronidase-active meningococci constituted 80-88 %. The percentage of the carriers of hyaluronidase-active meningococci causing cases of the generalized form of meningococcal infection varied in different groups. According to the results obtained in this study, the threshold percentage of such carriers constituted 30 in preschool institutions, 36 in boarding schools and 50 in common school and in hostels for adults. 相似文献

The article deals with the results of the epidemiological analysis of the spread of salmonellosis in Moscow. During the last 15 years the proportion of Salmonella enteritidis was about 80% and more. After salmonellosis morbidity decreased to 19.9 per 100,000 of the population (the minimum level) in 1985 its sharp rise was noted. Morbidity rate increased from 31.7 in 1987 to 55.1 per 100,000 in 1988, then to 93.9 per 100,000 of the population in 1989 (the maximum level). In the subsequent years up to 1996 a decrease in morbidity rate was observed, but in 1997-2002 morbidity rate stabilized within 29.8-35.7 per 100,000 of the population without a perceptible tendency towards decrease. The sharp increase of the etiological role of S. enteritidis which led to a wide spread of Salmonella infections was caused by the "chicken-egg" factor of their transmission. High morbidity rate among children and adults, registered all the year round, is the consequence of the constant epidemic activity of this factor. 相似文献

Retrospective analysis of the epidemic of HIV infection in Moscow allowed to mark out two periods: the first--from 1987 to 1993 and the second one--from 1994 to 2000. The characteristic feature of the first period of the epidemic was the sexual transmission of the agent mainly among homosexuals; the most affected group were persons aged 20-39 years and the number of AIDS patient decreased with a simultaneous growth in lethality. During the second stage of the HIV infection epidemic changes in the prevailing transmission routes of the agent occurred: injection drug addicts took the leading role. Changes in the ratio of HIV-infected men and women took place along with active involvement of persons aged 13-18 years into the epidemic process. The established changes in the epidemiological situation require corrections in the strategy and tactics of epidemic control and prophylactic measures. 相似文献

The possibility of the retrospective epidemiological diagnosis of viral hepatitis non A, non B with the fecal-oral mechanism of the transfer of infection in three cities of Central Asia on the basis of the analysis of the dynamics of registered hepatitis A morbidity is shown. With the irregularity of morbidity levels among the total population being characteristic of all three cities, in Andizhan one rise in morbidity within a period of 3 years (1975-1978) and in Tashauz one rise within a period of 5 years (1975-1980) were registered. The analysis of the dynamics of morbidity observed in individual age and social groups showed that these rises, especially those registered in 1976 in Andizhan and in 1977 in Tashauz, were determined by morbidity levels among school children and adults. This is also true for a rise in morbidity rate registered in Tashauz in 1985. In Andizhan the highest morbidity rates among adults were registered in districts insufficiently equipped with modern amenities. Cases of infection registered as hepatitis A (HA) among persons immune to HA at territories with high intensity of the epidemic process of HA at the above-mentioned periods seem to be due to viral hepatitis non A, non B with the fecal-oral mechanism of the transmission of the infective agent. 相似文献
