This descriptive study, based on national surveillance data of reported malaria cases, travelers’ statistics and data on malaria chemoprophylaxis prescriptions, estimates the incidence and trends of imported malaria in the Netherlands.
The extinction of dengue through natural vulnerability of its vectorsArchived
Aedes aegypti is a highly specialized mosquito species feeding predominantly on humans and breeding in artificial water holding containers in urban areas, and currently restricted to subtropical and tropical areas. Williams et al. focus on the reasons why Ae. aegypti once occurred in locations where the mosquito does not occur anymore in Australia, the more temperate drier parts of the country.
Evidence of simultaneous circulation of West Nile and Usutu viruses in mosquitoes sampled in Emilia-Romagna region (Italy) in 2009Archived
In recent years human diseases due to mosquito-borne viruses were increasingly reported in Emilia-Romagna region (Italy), from the chikungunya virus in 2007 to the West Nile virus (WNV) in 2008. An extensive entomological survey was performed in 2009 to establish the presence and distribution of mosquito arboviruses in this region, with particular reference to flaviviruses.
Surveillance of the chikungunya vector Aedes albopictus (Skuse) in Emilia-Romagna (northern Italy): organizational and technical aspects of a large scale monitoring systemArchived
The chikungunya virus outbreak that occurred in 2007 in northern Italy (Emilia-Romagna region) prompted the development of a large scale monitoring system of the population density of Aedes albopictus (Skuse, 1894), comparable at the provincial and municipal levels. In 2007, egg density data presented an aggregated distribution (VMR &gt;1) and Taylor's power law was applied to calculate the minimum number of ovitraps needed to obtain the prefixed precision levels: D=0.2 in the areas where the chikungunya epidemic occurred and D=0.3 in all the other urban areas &gt;600 ha.
West Nile fever: 12 new cases in the EU and 44 in neighbouring countries reported in the past week

During the past week, 26 new cases of West Nile fever were detected in the EU, which is the highest number of new cases for a week for the 2013 season so far.
Epidemiological update: End of West Nile virus transmission season in Europe, 2013
Since 5 June, ECDC has published on its website weekly updates on spatial distribution of West Nile fever cases in the European Union and neighbouring countries. Cases reported in the EU were autochthonous human WN fever cases (neuro-invasive and non neuro-invasive), meeting laboratory criteria as per EU case definition (Directive 2008/426/EC) and all reported cases outside the EU.
