[Malaria in Moscow in 2000-2004].

Malaria was eradicated on the territory of Moscow in 1960; its imported cases mainly from the countries of Asia and Africa and sporadic cases secondary to the imported ones were recorded during the following 40 years. Mass migration of the population (businessmen, seasonal workers, etc.) from the endemic CIS countries in the late 1990s, particularly to the Moscow Region, increased cases of tertian malaria, resulting from the transmission of the infection by the mosquitoes Anopheles. A total of 793 cases of malaria, including 27 parasitic carriers, were recorded from 2000 to 2004. The proportion of Muscovites was 24.1% of the total cases of malaria in 2002 and increased up to 50% in 2004. The causative agents of tertian malaria (Plasmodium vivax) were detected in 74.8% of the total number of cases. The ongoing importation of malaria from Tadjikistan and Azerbaijan, the late establishment of final diagnosis, the shortage of antimalarial drugs make the malaria situation worse in Moscow, which requires that antiepidemic measures should be intensified in the coming 3 years.
