“…The figure was computed on the assumption presently used that only one tick per pool was infected and regards only questing ticks, either nymphs or adults. This estimate is in line with data recorded during ecological evaluations carried out in Northern and in Central Europe, where the reported prevalence rates ranged from 0.2% to 2.0% when questing ticks were examined [Han et al, 2001;Suss et al, 2002;Melik et al, 2007;Brinkley et al, 2008], while prevalence rate raised to 9% in ticks removed from humans [Suss et al, 2006]. A number of reasons could be stated to explain the expected low presence of TBEV in this ecological context.…”

In Alpine area of extreme North Eastern Italy the first autochthonous case of TBE was reported in 1998 and was followed by 45 cases during the period 2001-2007, thus defining this area as definitely endemic. An ecological survey evaluated the tick density and the Tick-borne encephalitis virus (TBEV) infection prevalence in tick collected in selected sites. In addition, TBE strains were characterized by sequencing and phylogenetic analysis. Overall, 2,361 ticks (2,198 nymphs and 163 adults) of the Ixodes ricinus L. species collected during 2005 and 2006 were examined. Five samples were positive for TBEV, corresponding to an overall prevalence rate of 0.21%. When analyzed by place, TBEV was discovered in three sites where the highest tick density was found. The difference of prevalence between high and low density areas tested to be statistically significant (P = 0.028). Phylogenetic analysis showed that four sequences clustered with the Neudoerfl prototype, while the other clustered with the Isosaari 17 strain and with a number of Slovenian isolates. In addition, a sequence detected in archival samples from one human case segregated with another variant, namely the Swedish Torö strain.

“…Our prevalence in ticks detached from humans was in the same range as in field-collected ticks from Sweden (0.1 -0.42 %) (Brinkley et al, 2008). However, in that study the field-collection of ticks was done at local hotspots for TBEV, where several patients had contracted TBEV.…”

“…It is known from previous studies that the overall prevalence of TBEV in ticks usually is low (Table S1), and also that from Sweden and Norway the majority of TBEV infected ticks have a virus amount around the detection limit (Andreassen et al, 2012;Brinkley et al, 2008).…”

Abstract:The evidence of observed health effects as well as projections of future health risks from climate variability and climate change is growing. This article summarizes new knowledge on these health risks generated since the IPCC fourth assessment report (AR4) was published in 2007, with a specific focus on the 53 countries comprising the WHO European Region. Many studies on the effects of weather, climate variability, and climate change on health in the European Region have been published since 2007, increasing the level of certainty with regard to already known health threats. Exposures to temperature extremes, floods, storms, and wildfires have effects on cardiovascular and respiratory health. Climate-and weather-related health risks from worsening food and water safety and security, poor air quality, and ultraviolet radiation exposure as well as increasing allergic diseases, vector-and rodent-borne diseases, and other climate-sensitive health outcomes also warrant attention and policy action to protect human health.
