Dengue and dengue haemorrhagic fever (DHF) is a rapidly spreading disease in the tropics that have become the most serious arboviral disease in humans. Currently there are more than 2 billion people at risk of dengue fever in the world and millions of people are affected each year. In Southeast Asia, DHF has become a major cause of hospital admissions and deaths in children. The number of DHF cases in these areas has increased 300-fold over the past 20 years, with more than 60,000 DHF cases occurring in 1987 alone. DHF was introduced to the Americas in the 1980s.
