[The epidemic situation with malaria in Turkmenistan].

As a result of comprehensive research on the causative agents and vectors of malaria and wide use of synthetic antimalarials and highly effective residual insecticides, endemic malaria was eliminated in Turkmenistan by 1960. During the period 1965-1980, 23 local cases of malaria were recorded in Turkmenistan. These local cases were confined to the regions of Mary and Akhal, on the borders of neighbouring countries. In 1998 the epidemiological situation in the country worsened and local transmission of infection resumed. During the year the number of cases recorded was 137:134 being a first diagnosis of the disease and three being relapsed cases. In comparison with 1997, the previous year, incidence was up by 123 cases (a 9.7-fold increase), while the incidence of imported cases of malaria went up by 11 (a 2.2-fold increase), principally in Dashkhovuz and Lebar regions, being brought in from malaria foci in Gushgin district, Turkey, Azerbaijan and Tadjikistan. Local transmission of malaria went up by 111 cases (a 27.7 fold increase); 108 cases were recorded in Gushgin district, Mary region. The first case of malaria in Gushkin district was detected in June 1998. At that time there were five active foci. The approximate number of inhabitants in the active focus area was 10,000. The appearance of local malaria in border districts was caused by the periodic influx of infected mosquitos from neighbouring countries (Afghanistan).
