Dengue is an infectious disease of viral cause, which usually presents as a febrile illness called dengue fever. is characterized by an acute febrile illness of limited duration (2-7 days), with intense malaise (headache, retro-ocular pain, muscle aches and joint pain), accompanied by a rash. bleeding may have symptoms of low intensity, such as petechiae, epistaxis andgingival bleeding. such treatment is symptomatic and the patient improved completely after about 7 days. This form of dengue is benign and does not produce death
80% of people who are infected with dengue will be asymptomatic, undifferentiated fever 10% and 5% with or without fever, dengue haemorrhagic manifestations.
dengue hemorrhagic fever, less frequent (5% of clinical cases), includessymptoms of dengue fever, the hemorrhagic manifestations that are added to increase vascular permeability and abnormal clotting mechanisms. the main risk factor for the occurrence of this type of dengue is having had a previous infection by another serotype of dengue, but also influence the geographical origin of the viral strain and host susceptibility. the dengue shock syndrome includes moreserious picture of DHF plus signs of shock: weak or rapid pulse, decreased pulse pressure, hypotension, clammy skin and general unrest. so the disease begins suddenly with fever, and in children with mild symptoms of upper respiratory tract, often with anorexia, flushing and mild disturbances in the gastrointestinal tract. the patient's condition suddenly deteriorated with signs of profound weakness,severe restlessness, profuse sweating and abdominal pain. DHF is the severe form of the disease and produce shock and death if not adequately and timely question.
How is it transmitted?
Dengue is transmitted by the bite of female mosquito Aedes aegypti and Aedes albopictus lesser extent, that must be infected with the virus. the mosquito is a carrier, and therefore infective after 8-12days of being fed with blood from an infected person remains infectious virus and the rest of his life. sick people can infect mosquitoes from shortly before the end of the febrile period, averaging three to five days. the disease is not transmitted from person to person.

types of dengue
There are four dengue virus serotypes: 1,2,3 and 4. the first time a person is infected by any of these four virus acquires the dengue fever. dengue will never suffer the same virus, but remains exposed to the other serotypes.
if the personreturns to be bitten by a mosquito carrying one of the three remaining virus, dengue hemorrhagic fever may occur.
symptoms of dengue fever

• bleeding in various body parts of the body
• difficulty in breathing
• pressure changes
• lack of appetite
• pale,sweating and sleep.
