Most dengue infections result in fever which is mild but some pregresses into the haemorrhagic fever. In Dengue hemorrhagic fever, the blood vessels start to leak and cause bleeding from mouth, nose, and gums. Without having good treatment the blood vessals will collapse and cause shock which is called dengue shock syndrome. This fever turns fatal. There is no such treatement for dengue fever except for the fact that recovery occurs in 2 weeks time. Asprin should not be taken during the fever. Hence if the fever is persistent for more than two days it is always advisable to approach the Doctor and get your self treated. Dengue created a wave of deaths in Delhi during the recent times. The hospitals offered free of cost checkup for the detection of Dengue.

Dengue fever is an infectious disease carried by mosquitoes and caused by any of four related dengue viruses. This disease used to be called "break-bone" fever because it sometimes causes severe joint and muscle pain that feels like bones are breaking, hence the name. Health experts have known about dengue fever for more than 200 years.
Another case that struck soon after Dengue was the Chickungunya. As the name suggests it is not a chicken disease or the bird flu which too was in news not far back, it is also spread through mosquitoes. It was more prominent in the south ie Kerala, Tamil nadu, Karnataka where a lot of people died due to Chickungunya. Chickungunya is a rare form of viral fever which is caused by the alpha virus and ofcourse is spread by mosquito bites from the Aedes aegypti mosquito. It is not however fatal but above 200 deaths have been reported in the south.
Now analysing the symptoms of this disease include high fever which reach 102.2 degree F, a petechial or maculopalpular rash involving the limbs and trunk, and arthritis affecting multiple joints which can be debilitating. The symptoms are headache, conjuctival infection, and slight photophobia. The fever lasts for 2 days and then comes down. There is also joint pains, headache, insomnia accompanied.
These diseases do not have a preventive vaccine or medicine. It is just being developed. Hence it is better to prevent it and tking necessary steps to keep your sorroundings clean, dress in full dresses, use mosquito repellents or nets, check the water in coolers and so on. The Aedes mosquitoes usually bite during erly morining hours and late afternoon before dark.

Dengue (DF) and dengue hemorrhagic fever (DHF) are caused by one of four closely related, but antigenically distinct, virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4), of the genus Flavivirus. Infection with one of these serotypes provides immunity to only that serotype for life, so persons living in a dengue-endemic area can have more than one dengue infection during their lifetime. DF and DHF are primarily diseases of tropical and sub tropical areas, and the four different dengue serotypes are maintained in a cycle that involves humans and the Aedes mosquito
Dengue fever (IPA: ['de?ge?]) and dengue hemorrhagic fever (DHF) are acute febrile diseases, found in the tropics, with a geographical spread similar to malaria. Caused by one of four closely related virus serotypes of the genus Flavivirus, family Flaviviridae, each serotype is sufficiently different that there is no cross-protection and epidemics caused by multiple serotypes (hyperendemicity) can occur.
It is transmitted by the bite of infected Aedes mosquitoes, especially A. aegypti. Classical dengue (dengue fever) is self-limiting and characterized by fever, myalgia, headache, and rash. DENGUE HEMORRHAGIC FEVER is a more virulent form of dengue virus infection and a separate clinical entity.
