The virus that causes dengue fever is carried by female mosquitoes "Aides Aegypti", it normally feeds during the daytime, and is transmit their virus to humans through their bite. It is more likely to occur during or after the rainy season. Dengue fever can occur to people of all ages but it mostly affects children under the age of 15 years, but can occur in all age groups. Avoiding mosquito bites during the day time is a critical precautionary measure. Infection with one dengue serotype provides lifelong immunity but each individual can eventually be infected by other 3 serotypes. Several serotypes can be in circulation during an epidemic. The virus of the mosquitoes is not contagious and cannot be spread directly from person to person. There must be a person-to-mosquito-to-another-person pathway.
Other Names of Dengue Fever are: Dandy fever, Three-day fever, Breakbone fever. It is called as Breakbone Fever because the Victims of dengue often have contortions due to the intense joint and muscle pain, hence it has named as breakbone fever.
Dengue is prevalent throughout the tropics and subtropics. Outbreaks have occurred in the Caribbean, including Puerto Rico, the U.S. Virgin Islands, Cuba, and Central America. Cases have also been imported via tourists returning from areas with widespread dengue, including Tahiti, the South Pacific, Southeast Asia, the West Indies, India, and the Middle East.
Ayurvedic Name of Dengue Fever is "Dandak Jwara"
Causes of Dengue Fever :
Signs & Symptoms of Dengue Fever
The time between the bite of a mosquito carrying dengue virus and the start of symptoms averages 5 to 7 days, with a range of 3 to 14 days. An infected person cannot spread the infection to other persons but can be a source of dengue virus for mosquitoes for about 6 days. When mosquitoes bite an infected person and then it bites another person then the virus is transmitted to one person to another. There are several signs and symptoms of dengue, some of them are as follows:
Signs & Symptoms of dengue include:
These symptoms last for two to three days. Afterward, the fever drops and the patient experiences heavy sweat, but feel better for around one day.
In more severe cases, patients have fever and headache, and then develop a cough. The dengue virus causes the blood vessels to swell and leak, creating small purple colored spots on the skin, called petechiae. The skin may appear bruised in areas where the bleeding is worse. Bleeding into the stomach causes severe abdominal pains and vomiting of a black, grainy substance that looks like coffee grounds. The damaged blood vessels eventually become so large that they are unable to supply the needed blood flow and the oxygen it carries to the body's tissues. This causes the body to go into shock, and can damage major organs such as the heart and kidneys.
Dengue hemorrhagic fever (DHF) or Dengue shock syndrome (DSS)
Dengue hemorrhagic fever is a life threatening complication that is characterized by high fever, hemorrhagic (bleeding) phenomena - often with enlargement of the liver and in severe cases circulatory failure. The illness commonly begins with a sudden rise in temperature accompanied by facial flush and other symptoms of dengue fever. The fever usually continues for two to seven days and can be as high as 40-41°C, (104 to 106 degree Fahrenheit). Mostly the severe cases of dengue hemorrhagic fever occur in children.
Symptoms of Dengue Hemorrhagic Fever
Diagnosis of Dengue Fever
Diagnosis is made on the basis of clinical symptoms and blood test. The earlier detection is the only cure for this illness.
Treatments of Dengue Fever
If symptoms of Dengue hemorrhagic fever are seen immediately report to your doctor or visit to the hospital for treatment.
Because dengue is caused by a virus, there is no specific medicine or antibiotic to treat it. For typical dengue, the treatment is purely concerned with relief of the symptoms. Rest and fluid intake for adequate hydration is important.
Preventions of Dengue Fever
At present, the only method of controlling or preventing dengue and DHF is to combat the mosquitoes. Aedes aegypti breeds primarily in man-made containers like earthenware jars, metal drums and concrete cisterns used for domestic water storage, as well as discarded plastic food containers, used automobile tyres and other items that collect rainwater. Discard or dry these items.
