Answer 1

Nowadays many people suffer from dengue. Dengue fever is an
infectious disease carried by mosquitoes and caused by any four related dengue
viruses. This disease used to be called break-bone fever because it sometimes
causes severe joint and muscle pain. Dengue fever is a quite dangerous febrile
(Feverish) disease can be found in the tropics and Africa. Dengue fever is
transmitted by Aedes Aegypti mosquito, which also transmits diseases as yellow
fever.

Health experts have known about dengue fever from more than
200 years. Dengue or dengue-like epidemics were reported throughout the 19th
and early 20th centuries in America, southern Europe, north Africa,
the eastern Mediterranean, Asia and Australia and various Islands in the Indian
Ocean, the south and central Pacific and the Caribbean. It has steadily
increased in both incidence and distribution over the past 40 years. Annually,
it is estimated that there are 20 million cases of dengue infection, resulting
in around 24,000 deaths. Dengue fever is a flu-like viral disease common
throughout the tropical and sub-tropical regions around the world, mainly in
urban and pre-urban areas. Today, it afflicts (cause physical pain and
suffering) an estimated 50 million to 100 million in the tropics.

Answer 2

 Dengue fever is a flu-like viral disease common throughout the tropical and sub-tropical regions around the world, mainly in urban and peri-urban areas. Today, it afflicts an estimated 50 million to 100 million in the tropics (Epstein, 2000). The virus has four antigenically related serotypes, which are named DEN-1, DEN-2, DEN-3, and DEN-4. Each dengue serotype is a variation of the flavivrus genus. Dengue is spread by the aedes aegypti, a domestic, day-biting mosquito that prefers to bite humans. Currently, there is no vaccine available to prevent dengue. 
             Each type of the dengue virus is re-emerging worldwide, especially in the Western Hemisphere. Research has shown that several factors are contributing to the resurgence of dengue fever such as uncontrolled urbanisation, increased international travel, substandard socio-economical conditions, and finally global warming. Global warming has shown to be a major contributor to the spread of dengue fever.
