In Astrakhan region for the period from 2000 to 2014 there were registered 90 cases of human malaria, including imported cases from the CIS — 70 (78 %), secondary from imported — 11 (12 %) and relapse — 9 (10 %). Geographically, the foci of malaria were distributed as follows: Astrakhan — 58 foci (65 %), including Leninskyi district — 27 cases (46 % of all urban cases), the Kirov and the Soviet districts — 15 foci (26 %) and Truso district — 1 case (2 %) and passing through Astrakhan — 2 foci (2 %); Astrakhan region — 30 sites (33 %), including Krasnoyarsk district — 9 sites (30 %), Narimanov district — 8 CL. (27 % of all rural cases), Akhtubinsky district — 5 cases (17 %), Kharabalinskyi district — 4 sites (13 %), Chernoyarskyi district — 2 sites (7 %), Kamyziakskyi and Limansky districts 1 site (3 %). Conclusions. On the territory of Astrakhan region throughout the transmission season of effective contamination of mosquitoes (May — September) over the last 10 years there have been imported cases of malaria. The maximum number of reported imported malaria cases was observed in 2001 — 35 cases. In Astrakhan region the most frequently recorded is the three-day malaria — 94 %. The importation of malaria in the region was carried out in 78 % of cases from Azerbaijan and Tajikistan. After a long break, in Astrakhan region there were registered new active lesions, indicating the presence of secondary from imported malaria cases and the emergence of new active foci of the 1st degree. The disease was recorded more often in the warmer months, as evidenced by the incidence — 80 % of all reported cases.
