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 >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 >600 ha.
Elimination of rubella and prevention of congenital rubella infection in Europe has been a high priority for the WHO European Regional Office over the past decade. In 2010 the WHO regional committee for Europe renewed its commitment to the elimination of rubella and prevention of CRS with a new target of 2015. For Central Europe to reach the target of rubella elimination and prevention of CRS by 2015, very high vaccine coverage levels need to be maintained and catch-up campaigns continued to address susceptible groups, in particular women of child-bearing age.
According to the available epidemiological and entomological information, and the arriving winter season, the intensity of malaria transmission in Evrotas, Lakonia in Greece is believed to be very low and is expected to cease shortly.
On the 26 October 2011, The Lancet Infectious Diseases published a systematic review and a meta-analysis, combining the results of several studies undertaken on influenza vaccine effectiveness.
This is an authoritative independent evidence-based review and meta-analysis of the efficacy and effectiveness of influenza vaccines. It confines itself to trials and observational studies where diagnostic tests confirmed influenza infection as the end point.
The one-day workshop was the 2nd of a series of workshops in support to the Council Recommendation of December 2009 that encourages EU and EEA Member States to adopt and implement action plans or policies to improve seasonal influenza vaccination coverage.
The 2011 seasonal influenza immunisation campaigns have started across Europe. As in previous years ECDC is marking the start of the 2011-12 surveillance season in Week 40 with the publication of regular weekly updates of the main epidemiological and virological developments in the Weekly Influenza Surveillance Overview (WISO).
In an editorial in the scientific journal Eurosurveillance, ECDC noted that, based on numerous studies, paediatricians, family practitioners and nurses form the backbone of each national immunisation programme in the EU.
The tiger mosquito (Aedes albopictus), vector of several emerging diseases, is expanding into more northerly latitudes as well as into higher altitudes in northern Italy. Changes in the pattern of distribution of the tiger mosquito may affect the potential spread of infectious diseases transmitted by this species in Europe.
