  • The Danube is the river crossing Central and Eastern Europe classified as international waterway, through ten countries: Germany (7.0% of basin area), Austria (10.0%), Slovakia (5.9%), Hungary (11.6%), Croatia (4.4%), Serbia (10.2%), Bulgaria (5.9%), Romania (29.0%), Moldova (1.6%) and Ukraine (3.8%). The river has three main sections: (1) from spring to Devin Gate (Upper Section), (2) from Devin Gate to Iron Gate (Middle Section), and (3) from Iron Gate to Sulina (Lower Section).

    Over the time this river was either the barrier, either travel way for pathogens.

    The last twenty years raised geopolitical changes in the area, the open borders and free movement of goods and people have led in countries bordering the river to the emergence or re-emergence of serious diseases in humans and animals.

    Map’s design that shows where they were reported emerging or re-emerging diseases is one of the primary data requested to build-up strategies for the prevention of trans- boundary diseases transmission.

    • The CCHFv infection emerged or re-emerged in southeastern Europe, at least in Bulgaria, Albania, Kosovo, Greece and Turkey.

    • The TBEv infection is endemic in western and central European countries and is estimated with high risk of emergence in Albania, Bosnia and Herzegovinia, Bulgaria, Greece, Kazakhstan, Serbia and Montenegro, Moldova and Romania.

    • New Francisella tularensis spp. isolates emerged or re-emerged in Austria, Germany, Hungary, Italy, and Romania; and Borrelia burgdorferi sensu lato began making new victims in Romania.

    • That for we strongly support the setting-up/improvement of active surveillance programs of previously CCHFv, TBEv, Francisella tularensis and Borrelia burgdorferi sensu lato in the area of the Danube River’s lower section.

    CCHF virus has been found among ticks in Africa, Asia,

    the Middle East, and eastern and south-western Europe.

    European human infection cases of CCHF : Albania,

    Armenia, Bulgaria, Kazakhstan, Kosovoi, Russia,

    Serbia, Tajikistan, Turkey, Turkmenistan, Ukraine, and

    Uzbekistan.

    European human infection cases of tularaemia reported

    in EU/EEA countries (2007–2011): Austria, Bulgaria,

    Czech Republic, Estonia, Finland, France, Germany,

    Hungary, Italy, Lithuania, Poland, Romania, Slovakia,

    Slovenia, Spain, Sweden, Norway.

    European human infection cases of TBE reported in

    EU/EEA countries (2000–2010): Austria, Czech Republic,

    Estonia, Finland, Hungary, Italy, Latvia, Lithuania,

    Poland, Romania, Slovakia,Sweden, Norway.

    Dermacentor reticulatus Hyalomma marginatum Ixodes persulcatus Ixodes ricinus

    In tick-borne diseases the natural barriers play their role, as the Danube did, in limiting the dissemination of diseases such as those caused by Crimean–Congo hemorrhagic fever virus (CCHFv), Tick-borne encephalitis virus (TBEv) or Francisella tularensis and Borrelia burgdorferi sensu lato.
