[Spread of tropical malaria in the Republic of Tajikistan (1994-2008)].

Abstract

Tropical malaria occurred in the Republic of Tajikistan in 1994 after 40-year absence and spread in 28 regions of Tajikistan and in 3 cities (Dushanbe, Kulyab, and Kurgan-Tyube), peaking in 2000 (831 cases). A total of 3585 cases of tropical malaria were notified in 602 foci during a 15-year period. Migrants imported the pathogenic agent by the route of Pakistan-Afghanistan-Tajikistan during armed conflicts and in trading activities continually.The emergence of Asian Plasmodium falciparum phenotypes was accompanied by the clinical complications of the disease: the high percentage of moderate and severe forms of the disease was observed in preschool children in the absence of fatal outcomes. The rising incidence of malaria was associated with not only with the intensive import of the infection and the flight of infected malaria mosquitoes, but also with the active examination of the population during homestead rounds and with the timely laboratory diagnosis of malaria pathogens. The long-term goal antimalarial measures in the Republic of Tajikistan in 2009 resulted in the pause in the local transmission of tropical malaria, which meant its elimination in the country.
