Objective: to define clinical, epidemiological and entomological characteristics of malaria in the Krasnodar Territory in 2001-2014. Materials and methods. The clinical and epidemiological aspects of malaria in 25 patients hospitalized in the regional clinical hospital for the period 2005-2014 were studied. A comparative analysis of the incidence of malaria was done, entomological indicators of malaria season in the region for pathogens vivax in the last 3 years were considered. Results and discussion. In the Krasnodar Territory malaria is imported mainly from Africa (68%), more than half of cases (54.2%) - local residents, Russian citizens. Foreign citizens (Africans, migrants from Tajikistan) amounted to 45.8%. Basically middle-aged (21-59 years) men (88%) are subjected, traveling abroad for professional purposes, the tourists among the cases amounted to 15.4%. The residence time in an endemic area ranged from 16 days to 24 months, with regular chemoprophylaxis absence in 80% of cases. Cases of imported malaria in were recorded mainly from May to September, which corresponds to the epidemiological season with a high risk of disease transmission. In the etiological structure of imported malaria Pl.falciparum (64%) prevailed, cases of Pl.vivax were 32%, in one case (4%) Pl.ovale was found. Reference clinical and epidemiological features of imported malaria were acute onset of high fever, chills, headache, general weakness with the presence of the majority of patients with hepato-splenic syndrome, thrombocytopenia, in half the cases at a tropical malaria dyspeptic symptoms with increasing theirfrequencies in parallel of the disease severity were observed. For timely diagnosis, in addition to knowledge of the main clinical symptoms and disease complications, of paramount importance was the identification and registration of epidemiological history (stay in endemic area), knowledge of the disease phases, the duration of the incubation period for different kinds of invasions and timely screening for malaria patients with fever of unknown origin. Conclusion. Epidemiological and entomological studies confirm the presence in Krasnodar Territory of high malariogenic potential with the duration of the epidemic season, the possible transfer of the three-day malaria from May to October. Retention of the threat of imported malaria requires necessary level of knowledge among doctors in the diagnosis and prevention of malaria and ensuring effective health care facilities with antimalarial drugs.

For etiological diagnosis of acute respiratory viral infections the improvement of clinical semiotics and searchfor epidemiological consistent patterns are advantageous. Aim the establishment of consistent patterns of the clinical picture of etiologically AIRS decoded by PCR method and validities of epidemiological signs in the Primorsky Krai in the recent period. The material of the study were medical history cases on 276 patients admitted to the infectious department of Primorye Regional Clinical Hospital №2 in the city of Vladivostok in 2014 with a diagnosis of AIRS. Results. In the etiological structure of patients there was dominated influenza (48.2%). Hereafter there were: rhinovirus infection (13.0%), parainfluenza (11.2%), metapneumovirus infection (9,8,5%), adenovirus infection (8.0%). The minimum share was presented by bocavirus (HBoV)) infection (5.16%) and the respiratory syncytial virus, (HRSV) infection (4.7%). There were established the most sensitive and specific symptoms of considered infections. There were revealed features of the seasonality and the age structure of the patients, affecting on the efficiency of diagnosis.

In the work based both on epidemiological research and analysis of literature data, there are discussed methodological approaches to the assessment of riskfactors that could potentially influence on the development of the epidemic process. There are analyzed modern methods permitting to select the impact of main factors on the development of the epidemic process and the shaping of the certain epidemiological situation. There is emphasized the epidemiological importance of differential diagnosis in the implementation of such research.

There were studied epidemiological features of the prevalence rate of acute intestinal infections (AII) in the Republic of Dagestan (RD). The prevalence rate of acute intestinal infections in RD was shown to correspond taken as a whole, to Russian indices, however, the regional feature is the high prevalence rate of shigellosis, there is remained a high proportion of the AII of unidentified etiology. There was substantiated the necessity of development and implementation of targeted programmes aimed at the decline in the morbidity rate in problematic territories. The solution to the problem of the AII in the Republic is possible only under the coordination of efforts of federal and local authorities, sanitary - epidemiological and medical institutions.
