Dengue , is a plague disease in some countries (for illustration, in Brazil), and its most hazardous form is hemorrhagic dengue. It is caused by the four dissimilar but related viruses, the reason which it is difficult for an already infected person to turn out to be immunized against disease. Dengue is prevalent in tropical and subtropical regions of the Asia, Africa and South America and it is transmitted by bite of Aedes aegypti mosquito, a diurnal mosquito.

The viral infection causes varied symptoms alike to flu, such as fever, malaise, myalgia (muscle pain); in hemorrhagic dengue high fever, with or devoid of convulsions, and hemorrhages might take place leading to circulatory failure and death. There is no vaccine against dengue because there are four agent viruses and it is supposed that the severity of disease is superior when the patient is already protected against one kind of virus and is infected by another. The best prophylactic technique is to eliminate vector mosquito.
