Points of origin and regional dispersal of malaria on the territory of Vologda region

Malaria is one of the most widespread infectious diseases in the world. In 1958 malaria was eliminated on the territory of the Vologda region as a large-scale decease. Nowadays the conditions for emergence of malaria are still presented. Malarial mosquitoes are common throughout all the territory of Vologda region. Each year there are cases of bringing this desease from other regions. In the late 19th - early 20th century a high incidence (up to 40 000 cases) was recorded. The high number of malarial mosquitoes in the populated areas of the Volga-Baltic Canal and the Northern Dvina water system contributes to the emergence of local malaria. The first cases of malaria can be unnoticed. High temperatures in summer can cause the outbreak of malaria. Malaria is most likely to arise in the cities of Vologda, Cherepovets and Velikiy Ustyug.
