Increased Relative Risk of Tick-Borne Encephalitis in Warmer Weather

Frontiers in cellular and infection microbiology, 2018

Tick-borne encephalitis (TBE) is a serious acute neuroinfection of humans caused by a tick-borne ... more Tick-borne encephalitis (TBE) is a serious acute neuroinfection of humans caused by a tick-borne flavivirus. The disease is typically seasonal, linked to the host-seeking activity of (predominantly nymphs), the principal European tick vector species. To address the need for accurate risk predictions of contracting TBE, data on 4,044 TBE cases reported in the Czech Republic during 2001-2006 were compared with questing activity of nymphs monitored weekly at a defined location for the same 6-year period. A time shift of 21 days between infected tick bite and recorded disease onset provided the optimal model for comparing the number of cases of TBE with numbers of questing nymphs. Mean annual distribution of TBE cases and tick counts showed a similar bimodal distribution. Significantly, the ratio of TBE cases to questing nymphs was highest in the summer-autumn period even though the number of questing nymphs peaked in the spring-summer period. However, this pattern changed during a peri...

Es wird eine einfache Methode zur Herstellung von Repliken der Oberflchenstrukturen des Schildes der Zecke beschrieben.2. Mittels dieser Methode verarbeiteten wir mehr als 80 Zecken der Art Ixodes ricinus, Imagines beider Geschlechter, hungrige und angesaugte aus verschiedenen Lokalitten der SR und Rumnien. Sie stammten von verschiedenen Wirten.3. Die hexagonale Mikrostruktur des Scutums erwies sich als ein spezifisches Kennzeichen fr die Art Ixodes ricinus. Diese hexagonale Struktur bildet auf dem Schilde verschiedene Zeichnungen, welche sich ebenfalls als ganz konstant erwiesen.4. Weiter wurden die Verbreitung, Anzahl und Morphologie der dermalen Sensillen, die auf dem Scutum mnden, beobachtet.

The influence of meteorological conditions of the preceding winter on the incidences of tick-borne encephalitis and Lyme borreliosis in the Czech Republic

The relationship of the incidence of these diseases to meteorological characteristics of the preceding winter was examined. Included were data from 22 meteorological stations distributed over the territory of Bohemia in areas of high TBE and LB incidence (from the database of the Czech Hydrometeorological Institute, Prague). Nineteen factors characterizing the severity of winter as a whole were examined. The closest correlation (statistically not significant) was between the incidence of TBE and the frost index, followed by the minimum winter temperature during the preceding winter season. Several other comparisons revealed similar correlation coefficients slightly below the limit of significance, nevertheless, even they also support the finding that the severity of winter influences TBE incidence in the following season. The occurrence of LB correlated in similar, not fully significant manner. The most distinct results were achieved with the number of days of thaw and the number of ice days. For both diseases, the meteorological parameters indicating the severity of winter are inversely proportional.

Homogenized ticks were tested on PS cells, which were examined for any cytopathic effect, plaque assay and indirect fluorescent antibody test (IFT). The IFT has proved to be the most sensitive and most rapid test to demonstrate the virus in ticks. TBE virus was found in 17 of 187 pooled samples. consisting of a total of 2,968 ticks. The mean minimum infection rate was 0.6% for all tick stages combined. Infection rates in nymphs collected in different locations varied between 0.2 and 1.3% and between 5.9 and 11.1% in adult ticks. The observed TBE prevalence in ticks was compared with data obtained elsewhere in the Czech Republic. It is concluded that screening of ticks for TBE virus prevalence using IFT is a valuable indicator for the degree of risk to contrac...

This increase is clearly evident in the Czech Republic and it could be roughly characterised as twofold in 1993-2001 in comparison with 1984-1992 (5,240:2,441 human cases). As yet in the Czech Republic the TBE increase has been manifested by: a) higher number of cases in areas well known for TBE occurrence in humans; b) re-emergence in areas where TBE human cases were not observed, or only sporadically, for a long time; c) emergence of TBE in places unknown previously (including highly elevated areas). This phenomenon has not been fully elucidated yet and we would like to contribute to a better understanding of its cause by comparing the present situation with historical data. Besides TBE epidemiological data (1965-2001) we use the twenty-year all season dynamics data of Ixodes ricinus host-seeking activity (1953-1972) supplemented b...

Altitudinal distribution limit of the tick Ixodes ricinus shifted considerably towards higher altitudes in central Europe: results of three years monitoring in the Krkonose Mts. (Czech Republic)

(Czech Republic) and evaluate its potential changes. Two methods were used: monitoring of tick presence on dogs in 2001-2002 and direct monitoring of host-seeking ticks by flagging on two vertical transects reaching from 620 to 1270 m above sea level (a. s. l.) and from 600 to 1020 m in 2002-2003. Moreover ticks were monitored by flagging at another 13 localities situated in 800-1299 m a. s. l. in 2003. Both monitoring methods revealed an obvious shift in altitudinal distribution limit of the tick I. ricinus in the Krkonose Mts. They both showed that ticks recently penetrate even up to a timberline (approximately 1250 m a. s. l.). The number of recorded host-seeking ticks rapidly decreased with increasing altitude. Whereas the average number of recorded nymphs converted per 60 minutes of flagging reached 15.2-25.7 nymphs in 700-799 m a. s. l. and 3.3-23.3 in 800-8...

The altitude limit for ticks was observed and documented in the 1950s, and was the same in a study carried out in 1983. In 2002, the existence of I. ricinus was documented at 1080 metres in the Šumava mountains in the southwest of the country and at 1260m in the northern Krkonoše mountains, on the Polish border. Collected ticks were tested for infection with tickborne encephalitis (TBE) virus and B. burgdorferi genospecies. TBE virus was detected using PCR at 720 m, and Borrelia infection in ticks up to 1020m. Four genospecies of Borrelia were detected. The epidemiological consequences are assessed.

To obtain the necessary information in a scope which would enable its practical application in medicine to prevent populational exposure to ticks, remote sensing data were utilized as obtained from the Multispectral Scanner operating aboard Landsat 5. A file was selected from the full scene representing a territory which measured 41 by 41 kilometers and in the centre of which there was an area known to have consistently high tick numbers, as revealed in a 25-year continuous study of I. ricinus, and which proved to be a natural focus of tick-borne encephalitis. This area (Potepl) was taken as a model and was compared with its surroundings. Six landscape classes were examined (1--coniferous forest, 2--leaved forest, 3--mixed forest, 4--water basins, 5--glades, 6--housing developments), the former three being of crucial importan...

The goal of this study has been to find out to what extent a selected part of population is aware of ticks and of the relationship between ticks and LB. The study was based on a questionnaire survey. A total of 110 respondents were selected, including 19 secondary school students, 32 blood donors, 44 park-goers, 15 countryside people. As many as 99% of the respondents were aware of the presence of ticks, 91% knew that ticks are sucking blood of humans and animals, 1.8% thought they eat leaves. 74.5% of the respondents expect ticks to reach them from the vegetation while 22% believe that ticks fall from the trees. Furthermore, 87% and 75% of the respondents indicated to have had ticks attached to the skin or to have removed a tick from other persons&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; skin, respectively. Only 6.7% of them had never come into contact with ticks. 17% of the respondents use disinfectant when removing a tick, while 67% use oil for tick removal. Almost 30% remove ticks with naked hands. Over 14% destroy the ticks by squashing them with naked fingers. Finally, about 11% of the population studied had never heard about LB and 41% were not aware of the risk of tick-borne encephalitis.

Therefore, I. ricinus ticks, mainly nymphs, were investigated for the presence of tick-borne viruses, tick-borne encephalitis (TBE), Tribec and Eyach, and the spirochaete Borrelia burgdorferi sensu lato in the Sˇumava and Krkonosˇe Mountains (Czech Republic). The TBE virus and different genospecies of B. burgdorferi s.l. were detected by RT-PCR and PCR, respectively. TBE virus was detected in ticks at 620 and 720 m above sea level (a.s.l.), B. burgdorferi s.l. was detected in ticks up to 1065 m a.s.l. Four genospecies of B. burgdorferi s.l. were identified, B. afzelii, B. garinii, B. burgdorferi sensu stricto, and B. valaisiana. Some nymphs carried multiple Borrelia infections. The conditions of tick-borne agents' distribution and potential epidemiological consequences are discussed.

Tick-borne encephalitis virus was detected by means of RT-PCR. In 2003, it was detected in 2 out of 491 ticks at 620 and 710-720 m a.s.l., respectively, and in 3 out of 939 ticks at 600 m a.s.l. at the same locality in 2004. In 2005, tick-borne encephalitis virus was detected in 5 out of 295 ticks at 900-1100 m a.s.l., which is above the formerly known altitudinal limit of I. ricinus distribution. The reason for that could be found in the changing climate. Based on the meteorological data collected in the Krkonosˇe Mts., 1961-2005, there was a significant increase in the mean annual temperature (1.3-1.4 1C) over that period, namely by 2-3.5 1C in May through August. Thus, with respect to the average vertical temperature gradient in summer of about 0.6 1C/100 m, 2 1C correspond to 300-350 m in altitude, and accordingly 3.5 1C correspond to a shift in altitude of approximately 550-600 m, that being in accordance with environmental conditions of the former I. ricinus altitudinal limit confirmed in the Krkonosˇe Mts. 20 years ago. r
