ABSTRACT: Malaria is a globally spread disease, mostly in Africa, Asia and South America, where climatic conditions favour the spread of anophelian mosquitoes - living vectors of the causative agent of the disease.
Our aim is to study the imported parasitosis - malaria in Varna region and the general preventive measures (i.e. disinsection) for the period 2015-2019.
Materials and methods: Epidemiological analysis, documentary, statistical and graphic methods are used to evaluate the registered acute infectious diseases, RHI-Varna’s reports on the topic, as well as National programs and regulatory documents.
Results: Varna region is one of the risk regions in Bulgaria. The presence of anophelian mosquitoes’ biotopes (the vectors of infection) can contribute to local distribution. Varna Regional Health Inspectorate maintains a file with records of 126 main mosquito biotopes, grouped by settlement systems, with more or less frequently flooded area around them and many adjacent small water basins. Biotopes are subject to regular monitoring and research (the entire mosquito-active season from April to October). Until 2013, larvae and adults of the subfamily Culicinae were found in them, and after 2014 - anophelic mosquito larvae.
Conclusions: An organization has been established for conducting disinsection treatments in the municipalities of the district - imagicidal and larvicidal and seasonal dynamics with mosquito larvae in three controled biotopes on the territory of Golden Sands and two in St. St. Constantine and Helena. A total of 465 biotopes have been inspected and two genera mosquitoes have been identified: ANOPHELES and CULEX.
