Epidemiological studies on the spatial boundaries of Dengue virus transmission have shown that 3.8 billion people in 129 countries are currently exposed to the infection. According to data from the WHO, Dengue fever is now the fastest-spreading mosquito-borne disease. Between 50 and 390 million people worldwide are sickened annually, and half a million are hospitalized. 5)
Dengue attacks mainly on the Asian continent and can be found in South and East Asia (in such popular countries as Thailand, Cambodia, Vietnam, Laos, Philippines, Indonesia, India, Malaysia, and Sri Lanka ). Very many cases of the disease are also reported in Africa (Egypt, Kenya, Tanzania plus Zanzibar ), America ( Dominican Republic, Argentina, Brazil, Jamaica, Cuba, Mexico). 6)
It is also possible to record cases of Dengue disease in Europe! including on the island of Madeira in Portugal or Spain and other areas of the Mediterranean. This situation is certainly influenced by an increasingly warming climate and the establishment of mosquitoes in the area. 7)
