Clinical and epidemiological aspects malaria in Krasnodar territory

Abstract

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.
