Each country in the world has its specific occurrence of CVBDs (Companion Vector Borne Diseases: diseases transmitted by parasites – also called vectors - such as ticks, flies, fleas, sand flies and mosquitoes), depending on climate and endemic vectors. Based on current scientific knowledge and feed-back from experts around the world, the CVBD Occurrence World Map presents the country-specific situation in an easy-to-grasp way. The map allocates each country to certain occurrence levels, as explained in the legend, by assessing how many different companion vector-borne diseases are known to be endemic. Within a country, the occurrence of a disease may vary. Single autochthonous cases may occur furthermore, but are not implemented into the map at the moment.

Scrolling brings you to a specific country, and clicking on one of the coloured countries opens a window, stating the reported diseases, their pathogens and vectors. In some cases, additional information is listed.

Clicking onto one of the buttons in the left-hand side legend allows an overview on the occurrence of a specific companion vector-borne disease worldwide.
