1 Areas “affected” by malaria in Greece 2019 season, May 2019 The “Working Group (WG) for the designation of areas affected by vector-borne diseases” of the National Committee for the Prevention and Control of Tropical Diseases of the Ministry of Health has convened and decided upon which areas should be designated as “affected”, following the recording of an introduced P.vivax malaria case (1st generation of transmission) in 2019. The WG of experts has carefully examined the following data: the total epidemiological data concerning malaria in Greece since 2009, the number and characteristics of all cases reported to the National Public Health Organization (N.P.H.O.) up to 24th May 2019, the characteristics of the population to which they correspond, and the geomorphological characteristics of the corresponding areas, the available entomological data for the years 2011-2019, especially for the area with the introduced case, and the literature concerning the flight range of mosquito vectors, especially Anopheles sacharovi, which is considered to be the main malaria vector in our country. According to the suggestion of European experts, an “affected area” is defined as falling within a radius of 2-6 km around the probable place of exposure of the locally acquired cases. In Greece, an affected area is usually defined by a radius of 6 km around the probable place of exposure. However, if this defined circle includes sections of large urban centres or cities (that cannot be easily divided) or if a smaller radius is deemed adequate (e.g. based on entomological data, history of cases in an area, geomorphology, etc.), the WG - following risk assessment – decides upon the exact designation of the affected area. Consequently, the WG has concluded that: Α. Areas “affected” by malaria, based on the report of the introduced case (1st generation transmission) in 2019 (up to 24/05/2019), include the following areas (which are added to those of paragraph B): I.

Haemovigilance Measures (SKAE-N.P.H.O.) Guidelines for blood donors, in case of fever of unknown origin after blood donation, to inform the Blood Transfusion Service where they donated blood, regardless of the area. In case of malaria transmission after receiving transfusion of blood/Red Blood Cells, SKAE conducts a retrospective and trace-back investigation, in collaboration with the Blood Transfusion Services involved, for the identification and reexamination of the implicated blood donors.
