Malaria is an anthroponotic protozoan vector-borne disease which takes 2.6 % of all worldwide diseases. To estimate the level of malariogenic potential of a certain territory, air temperature data should be taken into account. Due to shifting the temperature patterns, climate change can create more appropriate conditions for malaria spreading; that is why it is important to estimate spacial distribution of malaria vectors and parasites for further evaluation of these species’ areal increase. In this research we have compared the temperature data (1991-2010) and prognoses (Shevchenko, 2014) for 5 main regions of Ukraine (Northern, Southern, Eastern, Western, and Central) with a temperature range tolerance for malaria vector (mosquito g. Anopheles) and parasites (P. vivax, P. malariae and P. falciparum).
Climatic conditions in Ukraine allow executing a full sporogonic cycle of P. vivax and P. malariae in mosquito organism in all regions during the summer period. To form sporozoites P. falciparum the average seasonal temperature should not be lower than 18 °С, which is not expected for Western part of Ukraine. Winter temperatures in Ukraine are not optimal for sporozoites development in the organism of a mosquito and can be regarded as limiting factors for malaria spread in winter.
