In order to ensure epidemiological surveillance and prevention measures aimed at preventing the occurrence of dangerous infectious diseases transmitted by mosquitoes, the ZikaMap geographic information system was used during the preparation and hosting the 2018 FIFA World Cup in Sochi. The use of this information resource allowed real-time visualization and analysis of data on monitoring the number and distribution of Aedes albopictus mosquitoes, monitoring the performance and effectiveness of insecticidal (larvicidal) treatments. The cartographic display of the radius of spread of mosquitoes from the points of their detection made it possible to determine the risks of their contact with epidemiologically significant objects and correct the treatment plan if necessary. The results of the analysis showed the effectiveness of the taken prevention measures (a total of 139 objects were processed on an area of 252.2 hectares). Entomological monitoring data at 692 observation points confirmed the localization of mosquitoes Ae. albopictus on the territory of city cemeteries and in the forest-park zone, but mosquitoes of this species were not found near the epidemiologically significant objects. The geographical information system ZikaMap is a domestic development and can be used to solve various problems of monitoring carriers and vectors for infectious diseases and for planning preventive measures.
