CLUSTER MAPS OF CHIKUNGUNYA VIRUS EPIDEMIOLOGICAL RISK IN EMILIA-ROMAGNA IN 2013

During the summer season 2013, 608 inhabited areas (in a range area from 2 to 7680 hectares) in 262 municipalities were monitored for Aedes albopictus in Emilia-Romagna region.

Using ovitraps data, aggregated for inhabited areas in the period of maximum Aedes albopictus density which coincides with the end of July and beginning of August 2013, was created a map of the Chikungunya virus epidemiological risk in 2013.

In the following map are shown, in red points, the inhabited areas exceeded the risk threshold for Chikungunya virus (CHIKV) according to the epidemiological model developed by the regional group (Carrieri et al 2012) in the weeks of maximum species density (weeks 31-32); In green points are reported the inhabited areas below this threshold.

Using spatial analysis techniques was subsequently created a map indicating  “hot spots” CHIKV risk.

i2

The map highlights, in bright red, two major hot spots in the health districts of Forlì and Cesena and health district of Riccione also covering the hilly areas and an area of ​​less intense hot spot in the western province of Bologna continues to the west of Ferrara province but with less intensity.

The map gives an overview of the indicative areas at greatest CHIKV epidemic risk in the summer 2013.
