By the late 1990s, dengue was the most important mosquito-borne disease affecting humans after malaria, with around 40 million cases of dengue fever and several hundred thousand cases of dengue hemorrhagic fever each year. Significant outbreaks of dengue fever tend to occur every five or six months.
Most people recover within a week or so. In about 5% of cases, symptoms worsen and can become life-threatening. This is called severe dengue (formerly called dengue hemorrhagic fever or dengue shock syndrome). [21] [23] Severe dengue can lead to shock, internal bleeding, organ failure and even death. [24]
Over the last twenty years, there has been a geographic spread of the disease. Dengue incidence rates have risen sharply within urban areas which have recently become endemic hot spots for the disease. [57] The recent spread of Dengue can also be attributed to rapid population growth, increased coagulation in urban areas, and global travel.
The median age of the deceased was 49 years, with a variation ranging from less than 1 year to 91 years. Deaths occurred in all age groups, with those over 80 years of age being the most affected, followed by the groups of 70 to 79, 60 to 69 and 30 to 39 years. However, the 30 to 39-year-old group recorded the highest number of cases overall. [10]

Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]
