[Monitoring of the malaria situation and the assessment of antimalaria measures in the Republic of Uzbekistan].

In 2008, the major malaria vectors An.superpictus and An. pulcherrimus amounted up to 50 specimens per premise in the Surkhandaryinsk and Kashkadaryinsk Regions. The high density of larvae in the water reservoirs (as many as 30-50 specimens per square meter) and rice fields (8-60 specimens per square meter) was noted in the Surkhandaryinsk, Namangan, Ferghana, and Tashkent Regions. There is a high susceptibility of the territory due to increased migration between Uzbekistan, Kyrgyzstan, and Tajikistan. In 2008, a total of 4,958,685 subjects passed through 68 border checkpoints, among them there were 835 (0.02%) individuals with suspected infectious diseases, including malaria. The foci of irrigation-ditch area and their conjugate foci of the floodplain-river one of the Surkhandaryinsk Region are most dangerous. Analysis of the trend of malaria foci showed a reduction in the number of new active foci from 44 in 2006 to 6 to 2008. The increased number of residual inactive and sanitized foci suggests that the malaria situation has considerably improved.
