Dengue infection is a leading cause of illness and death in the tropics and subtropics. Approximately 100 million people are infected yearly. It is a virus based disease spread by mosquitoes and Dengue is caused by any one of four related viruses transmitted by mosquitoes. It is spread by the bite of mosquitoes, most commonly the mosquito “Aedes aegypti”, which is found in tropic and subtropical areas. South and Central America, Southeast Asia, Sub-Saharan Africa. Up till now there is no any vaccine to prevent infection with dengue virus (DENV) and the most effective protective measures are those that avoid mosquito bites. Infections can be cured by early recognition and early treatment; it can lower the risks of developing its severe conditions. Dengue is also known by some other names, including "break bone" or "dandy fever." Sufferers of dengue often have contortions due to the intense joint and muscle pain, hence the name break bone fever.
In 1950, dengue arises as a worldwide problem. Mosquitos causing this disease usually flourish during rainy seasons, in water filled flower pots, plastic bags or water filled tanks. One mosquito bite can cause the disease and the virus is not contagious and cannot be spread directly from person to person. There must be a person to mosquito to another person pathway.
Dengue fever arises with a sudden high fever, often as high as 104 - 105 degrees Fahrenheit.

It results in the less percentage of platelets in victim’s blood.
