Dengue fever has emerged as a worldwide problem only since the 1950s.
The name ‘dengue’ is thought to have origins in the Swahili language, “Ki-Dinga pepo” used to describe a dengue-like illness reported in Africa during the 19th century.
The Dengue is cause of illness and death in the tropics and subtropics.
There are four types of viruses that cause dengue-fever worldwide. A person infected with one type of dengue will subsequently only be immune to that type.
Dengue is caused by any one of four related viruses transmitted by mosquitoes. Dengue and chickungunya two diseases are transmitted by Aedes aegypti. Dengue is the most common vector-borne viral disease in the world, virus infection may be subclinical, without symptoms, or may cause illness ranging from a mild fever to a severe, even fatal condition, haemorrhagic fever or shock syndrome.
Typical symptoms may include:
Erythematous skin on face and neck, peeling of skin and hair loss, sudden onset of fever, rash on arms and legs, severe itching, muscle and joint pain, intense headache, loss of appetite, vomiting, diarrhoea, abdominal pain and heavy menstrual periods. Excessive fatigue.
In the Dengue haemorrhagic fever, after 2-5 days onset of fever, appears cardiovascular disease, rapid deterioration, and sometimes shock and death.
Treatment:
Paracetamol, rest and lots of water, because dengue fever dehydrates quickly. Important rule: never take aspirin because it can cause bleeding and lead to shock.
Currently there are not yet any vaccines to prevent infection with dengue virus.(Abstract)
