“…For example, following the expansion in the geographic range of the tick Ixodes ricinus ( Jaenson et al 2012a, Medlock et al 2013, tick-borne diseases such as tick-borne encephalitis (TBE) and Lyme borreliosis are being found in new areas (Rizzoli et al 2011, Jaenson et al 2012b. Moreover, different interactions between people and the environment increase the numbers of humans exposed to ticks and tick-borne pathogens (Sumilo et al 2008). In addition, several emerging zoonoses, such as human granulocytic anaplasmosis (HGA) and babesiosis, that are caused by the obligate intracellular bacterium Anaplasma phagocytophilum and members of the protozoan hemoparasitic genus Babesia, respectively, are posing risks to humans in Europe (Doudier et al 2010, Hildebrandt et al 2011).…”

Tick-borne diseases pose an increasingly important public health problem in Europe. Rodents are the reservoir host for many tick-transmitted pathogens, including Anaplasma phagocytophilum and Babesia microti, which can cause human granulocytic anaplasmosis and babesiosis, respectively. To estimate the presence of these pathogens in rodents in Finland, we examined blood samples from 151 bank voles (Myodes glareolus) and demonstrate, for the first time, that A. phagocytophilum and B. microti commonly infect bank voles (in 22% and 40% of animals, respectively) in Finland. Sequence analysis of a fragment of 18S rRNA showed that the B. microti strain isolated was identical to the Munich strain, which is considered to be nonzoonotic. The A. phagocytophilum strain (based on a fragment of the msp4 gene) was identical to one found earlier in rodents in the United Kingdom that is transmitted by the tick Ixodes trianguliceps, all the life stages of which feed on small mammals. The infection probability of B. microti in the bank voles was the greater the older the individual was, and males were more often infected than females. A. phagocytophilum infection probability first increased and then decreased with the age of individual without any difference between sexes. While these pathogens presumably pose a limited zoonotic risk to humans in Finland, they might have important interactions with other rodent pathogens and therefore affect infection dynamics of, for example, zoonotic pathogens.

“…Temperature plays a very complex and controversial key role in the influencing of tick-human connection by increasing the questing activity of ticks and the human outdoor activity as well as by increasing the evaporation and cause lower relative air humidity. The latter has negative effect on tick activity, but sunny and dry summer days have positive effect on human outdoor activity (Šumilo et al 2008;Randolph 2010). The development of the IA showed a pronounced summer depression, maybe due to the effect of the summer drought on tick activity.…”

“…Human activity may have a great influence on the annual LB incidence (Šumilo et al 2008;Randolph 2010). We found that many other accommodation types show clear seasonality, but camping was the best suitable approach, because the inside temperature of tents depends on directly the outdoor temperature and humans prefer the sunny, mild, and windless days as ticks as well.…”

The change of ambient temperature plays a key role in determining the run of the annual Lyme season. Our aim was to explain the apparent contradiction between the annual unimodal Lyme borreliosis incidence and the bimodal Ixodes ricinus tick activity run -both observed in Hungary -by distinguishing the temperaturedependent seasonal human and tick activity, the temperature-independent factors, and the multiplicative effect of human outdoor activity in summer holiday, using data from Hungary in the period of 1998-2012. This separation was verified by modeling the Lyme incidence based on the separated factors, and comparing the run of the observed and modeled incidence. We demonstrated the bimodality of tick season by using the originally unimodal Lyme incidence data. To model the outdoor human activity, the amount of camping guest nights was used, which showed an irregular run from mid-June to September. The human outdoor activity showed a similar exponential correlation with ambient temperature to that what the relative incidence did. It was proved that summer holiday has great influence on Lyme incidence.

“…Which factors that contribute the most can differ geographically and is often hard to quantify. At the borders of the current TBEV distribution, climate change may have a role, while changes in TBE cases within core endemic areas appears better explained by socio-economic factors [137][138][139][140][141][142][143][144][145][146][147][148][149][150][151][152]. In the Baltic countries, increased risk of TBE has been correlated to socioeconomic factors, where lower educated, unemployed, and retired individuals are more often unvaccinated and visit the forest more frequently for recreation and picking berries and mushrooms [153].…”
