Preparedness for the detection of emerging-and re-emerging pathogens in Croatia Alemka Markotić, MD, PhD Associate professor University Hospital for Infectious Diseases Department for Research Department for Cinical Immunology Zagreb Croatia
History The University Hospital for Infectious Diseases was founded in the spring of 1893, under the name of the City Hospital for Contagious Diseases

Merdić E. et al., Infektološki glasnik (Croatian Journal of Infection) 2008; 1: 17-21. Out of 50 mosquito species recorded in Croatia, 15 have potential medical significance. Anopheles atroparvus, An. plumbeus, An. sacharovi, Culex pipiens, and Aedes albopictus are among the most significant species that are potential vectors in Croatia. Climatic changes play an important role in changing the condition of habitats, making it possible for new species to enter certain areas. The tiger mosquito was recorded in Croatia in 2004, and it can now be found in Istria, and more increasingly in Zadar, Šibenik, Split and Dubrovnik, with new sites found on the islands of Cres and Lošinj, which are very attractive tourist destinations.
