EPIDEMIOLOGICAL ASSESSMENT OF POPULATION MIGRATION IN THE POSSIBILITY OF CHOLERA IMPORTATION INTO RUSSIAN FEDERATION CONSTITUENTS

Abstract

Aim. Determination of potential epidemic hazard degree of migration in the possibility of cholera importation into the RF constituents with (without) the international border crossing points by air, sea, road and rail transport, as a component when determining the epidemic potential of the territory. Materials and methods. The data of the Rospotrebnadzor Directorates for 83 Russian Federation constituents, including 61 subjects with air, sea, road and rail transport border crossing checkpoints, taking into account the links with countries affected by cholera, and in 22 without international checkpoints ( 2011 — 2015) were used. The analyses of demographic indicators for characterizing intensity and determination the potential epidemic hazard degree of migration was carried out. Results. The increase in population due to interstate migration by various transports was determined in 83,6% subjects. The algorithm of epidemiological assessment was developed, with calculating the potential epidemic hazard degree (PEHD) of population migration in the possibility of cholera importation into 83 administrative subjects. The highest PEHD of migration was determined in 17 of 61 subjects with checkpoint sets; in 39 — higher than normal and in 5 — low; in 22 subjects without international checkpoints — in 8, 12 and 2, respectively. Conclusion. The obtained results indicate the presence of epidemiological risks associated with migration.
