Zusammenfassung
Die 11. Konferenz der International Scientific Working Group on Tick-borne Encephalitis (ISW TBE) stand unter dem Motto "Von der Kindheit bis zum Seniorenalter: erhöhte Mobilität – gesteigertes Risiko für FSME-Infektionen?". Teilnehmer aus 26 Ländern einschließlich den USA und China berichteten über die jüngsten Entwicklungen und Trends im Hinblick auf lokale FSME-Infektionen, Impfschutz und Risikofaktoren. Im Speziellen wurde die Situation der Kinder und der Senioren diskutiert. Der aktuellen Datenlage zufolge haben sich Lokalisation und Ausdehnung endemischer FSME-Areale in den letzten Jahren im vermuteten Zusammenhang mit der Klimaerwärmung und der Ausbreitung der Zecken in höher gelegene Gebiete geändert. Die gesteigerte Mobilität der Menschen verstärkt die Exposition weiter; Aktivitäten im Freien und internationale Reisetätigkeit nehmen zu, auch und vor allem bei Personen über 50 Jahren, bei denen bereits per se ein höheres Risiko für Krankheitsmanifestationen, Komplikationen und Tod besteht. Die meisten Europäer verreisen innerhalb von Europa und wissen dabei oft nicht über endemische Gebiete Bescheid. Auf lange Sicht kann nur eine hohe Durchimpfungsrate eine niedrige Morbidität sicherstellen. Die Information der Öffentlichkeit ist die einzige effektive Maßnahme, mit der ein entsprechendes Bewusstsein geschaffen und dieses Ziel umgesetzt werden kann. Insgesamt sollte das Risiko der einzelnen Person für eine FSME-Infektion nicht als fixe Größe angesehen werden, sondern muss im individuellen Fall mithilfe des Wissens um endemische Gebiete und Risikofaktoren abgeschätzt werden.
Summary
The 11th meeting of the International Scientific Working Group on Tick-borne Encephalitis (ISW-TBE) was conducted under the title of, "From childhood to golden age: increased mobility – increased risk of contracting TBE?" Participants from 26 countries, including the United States of America and China, presented reports on the latest developments and trends in local TBE cases, vaccination coverage and risk factors. In particular, the situation of children and the elderly (the "golden agers") was discussed. As the current evidence suggests, the location and extension of endemic areas for TBE have changed over the last few years, along with global warming and the shift of infected ticks to higher altitudes. The increased mobility of the human population adds to the heightened exposure; outdoor activities and international travel are on the rise also, and especially, amongst the 50+ generation, who are already per se at higher risk of disease manifestation, complications and case fatality. Most Europeans travel within Europe, often without sufficient awareness of endemic areas. Only high immunization rates can ensure low disease rates in the long run. To achieve this goal, public education is the sole effective approach for raising the level of awareness. Overall, the risk of any given person to contract TBE should not be regarded as a fixed entity, but rather it must be estimated individually, on the basis of knowledge of the TBE virus endemic areas and risk factors.
