Surveillance of vector-borne diseases in Germany: Trends and challenges in the view of disease emergence and climate change
Autor(es): Jansen Andreas, Frank Christina, Koch Judith, Stark Klaus
Resumo: The changing epidemiology of vector-borne diseases represents a growing threat to human health. Contemporary surveillance systems have to adapt to these changes. We describe temporal trends - geographic origins of vector-borne diseases in Germany with regard to strengths of existing disease surveillance - to areas marked for improvement. We focused on hantavirus infection (endemic in Germany), chikungunya fever (recently emerging in Europe) - dengue fever (imported from tropical regions), representing important subgroups of vector-borne infections. Routine surveillance data on demographics, origin of infection - the date of reporting were analysed. From 2001 through 2007, 3,005 symptomatic hantavirus infections, - 85 cases of chikungunya fever were reported, similarly 1,048 cases of dengue fever in 2002 through 2007. The geographic origin of hantavirus infection was reported for 95.5% of all cases (dengue virus, 98.4%; chikungunya virus, 100%). Hantavirus infections were acquired in Germany in 97.6% of cases (n = 2800). In 2007, there was a marked increase of hantavirus cases, mainly in areas known to be endemic for hantavirus. In 2006, imported cases of chikungunya fever primarily returned from several isl-s of the Indian Ocean, while the majority of imported cases in 2007 came from India. The reported number of dengue fever cases have increased since 2004. Thail- contributed the largest proportion of cases (17-43% in individual years), followed by India, Brazil - Indonesia. Surveillance of notifiable vector-borne diseases in Germany is able to timely detect spatial - temporal changes of autochthonous an imported infections. Geographic - temporal data obtained by routine surveillance served as a basis for public health recommendations. In addition to surveillance of vector-borne infections in humans, nationwide monitoring programs - inventory techniques for emerging - reemerging vectors - for wildlife disease are warranted.
