“…Considering the high TBEV prevalence observed in ticks detached from humans in previous studies (Klaus et al, 2010;Süss et al, 2006Süss et al, , 2004, we expected to find a higher overall prevalence than the observed 0.23 % (5 of 2167 ticks). 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).…”

“…In three studies from Germany, a significantly higher prevalence of TBEV was found in ticks detached from humans than in field-collected ticks from the same area (Klaus et al, 2010;Süss et al, 2006Süss et al, , 2004. There is also a report from Karelia in Russia showing a similar pattern (Kotovich, 2012).…”

“…The first is that TBEV is equally prevalent in questing ticks but the virus copy number is below the detection limit (Süss et al, 2006).…”

“…We did not find TBEV in any of the sampled ticks but a new TBE case was reported at site E in the fall 2015. Inability of the PCR assay to detect the virus in the questing ticks can be due to very low virus copy number (Suss et al, 2006) or lack of appropriate temperature required for riboswitch (Elvang et al, 2011). We could not confirm the suggested TBEV distribution based on confirmed cases of TBE, …”

Ixodes ricinus, a common tick in Europe, transmits severe tickborne pathogens (TBPs). In Sweden, both prevalence and incidence of tick-borne infections have increased during the last few decades, and a majority of the cases is reported from the area around Stockholm. Among ticks, transmission of TBPs involves co-feeding of susceptible larvae or nymphs with infected ticks on the same host. Seasonal synchrony of immature stages and total tick abundance are important factors for the probability of horizontal transmission of TBPs. We have studied the association between local landscape characteristics and population dynamics and the probability of co-occurrence of different life cycle stages of I. ricinus at different locations south of Stockholm, Sweden. We found significant spatiotemporal variation in tick activity patterns. Mean tick abundance varied with a tenfold difference among study sites. The probability of co-occurrence of larvae, nymphs and female adults was highest in June and decreased significantly with vegetation height. In addition, the amount of forest habitat and open water in the surrounding landscape of the study sites expressed significant negative effects on tick abundance and co-occurrence, indicating that environmental heterogeneity may increase the likelihood of good rodent habitats, which in turn, are suitable hosts for immature ticks.

“…In a recent Swedish study, the average prevalence of TBEV in field collected ticks was 0.23%, with a lower prevalence in nymphs (0.1%), than in adults (0.55%), but in a well-known highly endemic Island in the Stockholm archipelago the prevalence was 0.5% in nymps and 4.5% in adults [91]. In 3 German studies, a higher prevalence of TBEV has been observed in ticks detached from humans than in field-collected ticks from the same area (Table 1) [92][93][94]. Only a small proportion of infected ticks, both from the field and from humans, appears to have a high virus titer [95,96].…”
