About Dengue Virus/Fever

introduction of dengue

Dengue is a disease that causes a type of virus known as a flavivirus.

There are four different subtypes of the virus, which produces the various symptoms 

of the disease. The disease is transmitted between species of keltakuumehyttynen mosquito

bite. The disease is mainly tropical, and is endemic in many parts of Latin America, 

and South America. In recent years, the incidence is rising in Asian countries like India.

Dengue causes and pathogenesis

Dengue is transmitted to humans through the bite of a mosquito infected keltakuumehyttynen. 

Aedes mosquito breeds in fresh water they live relatively close to people's homes and snacks 

throughout the day. The incubation period between the onset of symptoms and bites, usually 

two to seven days. Aedes mosquitoes responsible for the spread of diseases such as yellow 

fever and Chikungunya virus as well.

Dengue symptoms and signs

A large number of infections may be asymptomatic, that is, patients may not even have had 

the disease. The infection usually manifests fever is a strong muscle pain or physical pain. 

There may be associated with a skin rash parts of the body. body pain is so intense that the 

disease is caused by the collapse of the bone fever. Very often, the pain does not offer any 

progress, and the patient recovered. However, some patients may develop involvement of 

a dreaded dengue syndromes - bleeding (known as DHF or dengue Hemorraghic) or the 

participation of consciousness in the brain (encephalitis). Deaths were higher in patients with 

complications are present. Joint pain is another symptom, although there can be a true 

arthritis. Related symptoms include severe headache, vomiting, and photophobia. 

The examination of patients may reveal some of the results, as a rash and pain in the 

palpation of the muscles. The symptoms usually last for a certain time by two five days and 

the majority of patients with complications completely.The Restore the risk of complications, 

it seems to be more young people, in particular, the risk of bleeding and DHF high mortality 

rate. Some patients may also be a surprise, which is called dengue shock syndrome (DSS). 

In addition, it is associated with a high risk of dying.

Dengue research and diagnostics

The diagnosis is based on clinical symptoms of dengue, information on where a person lives, 

and laboratory studies. Blood tests can show low white blood cell count, low platelet count, 

and increase the enzymes.The However, a definitive diagnosis is made by isolating the virus 

in human blood in the acute illness, or for the detection of antibodies to the virus in the blood. 

antigen detection is also possible. increase in antibody titer is useful as a diagnostic 

technique. Research should also be done to rule out other possible causes of fever such as 

malaria, and leptospirosis.

Dengue treatment and prognosis

The treatment is usually symptomatic and maintained. Analgesics, antipyretics and 

broad-spectrum antibiotics are used during the acute phase, in order to minimize the risk 

of secondary infection. In case of bleeding, transfusion of blood is required. Shock, 

where appropriate, need intensive treatment with liquid oxygen and careful supervision. 

The majority of patients recover without solution of continuity. the overall death rate of 

nearly 1%, an effective treatment, but may be higher in children.

dengue prevention

The control and elimination of mosquito populations is the best way to prevent it. 

The vaccine is under development, but it is not yet available for commercial use on 

a large scale. to control the mosquito population to reduce the incidence of dengue, 

yellow fever and other rare fever, transmitted by mosquitoes of the same type.
