How To Prevent Dengue

Since there has not been any vaccine to prevent dengue fever from being experienced by people yet, the only way to prevent it is to avoid the transmission of the virus to mosquitoes. To this end, patients are kept under mosquito netting until the second bout of fever is over and they are no longer contagious.

The prevention of dengue requires control or eradication of the mosquitoes carrying the virus that causes dengue. In nations that are often plagued by dengue fever, people are urged to empty stagnant water from old tires, trash cans, and flower pots because these are just some of the common places that dengue-causing mosquitoes lives. Governmental initiatives to decrease mosquitoes also help to keep the disease in check but have been poorly effective.

Another easy thing to do to prevent getting mosquito bites is to wear long pants and long sleeves. You can also make use of insect repellent sprays that contain DEET when visiting places where dengue is endemic. There are no specific risk factors for contracting dengue fever, except living in or traveling to an area where the mosquitoes and virus are endemic. Limiting exposure to mosquitoes by avoiding standing in water and staying indoors two hours after sunrise and before sunset will help. The Aedes aegypti mosquito is a daytime biter with peak periods of biting around the time of sunrise and sunset. It may bite at any time of the day and is often hidden inside homes or other dwellings, especially in urban areas.

Up to date, there is still no vaccination for preventing dengue fever from occurring. There is a vaccine undergoing clinical trials, but it is too early to tell if it will be safe or effective. Early results of the the said clinical trials show that a vaccine may be available within the year 2015.

Dengue Hemorrhagic Fever

Dengue hemorrhagic fever, or DHF, is a specific syndrome that tends to affect children under 10 years of age. It causes abdominal pain, hemorrhage (bleeding), and circulatory collapse (shock). DHF is also called Philippine, Thai, or Southeast Asian hemorrhagic fever because its cases are often seen in the said countries or others which are located in the tropics and subtropics. Dengue hemorrhagic fever is also called dengue shock syndrome.

DHF starts abruptly with high continuous fever and headache. There are also respiratory and intestinal symptoms with sore throat, cough, nausea, vomiting, and abdominal pain. Shock occurs two to six days after the start of symptoms with sudden collapse, cool, clammy extremities (the trunk is often warm), weak pulse, and blueness around the mouth (circumoral cyanosis).

In Dengue hemorrhagic fever, there is often bleeding with easy bruising, blood spots in the skin (petechiae), spitting up blood (hematemesis), blood in the stool (melena), bleeding gums, and nosebleeds (epistaxis). There are also cases on women wherein they experience too much bleeding as they menstruate. Physicians states that it is also a cause of Dengue hemorrhagic fever. Pneumonia is also common, and inflammation of the heart (myocarditis) may be present.

Patients with DHF must be monitored closely for the first few days since shock may occur or recur precipitously (dengue shock syndrome). Cyanotic (bluish colored) patients are given oxygen. Vascular collapse (shock) requires immediate fluid replacement. Blood transfusions may also be necessary to control bleeding.

Statistics show that the mortality (death) rate with DHF is significant. With proper treatment, the World Health Organization estimates a 2.5% mortality rate. However, without proper treatment, the mortality rate rises to 20%. Most deaths occur in children. Infants under a year of age are especially at risk of dying from DHF.

Facts You Need To Know About Dengue

About Dengue Fever
About Dengue Fever

Dengue fever can now be considered a common disease among people, especially in children. We all know that there are even more diseases that are worse than dengue but it is best if we kept cautious about it. By doing so, you need to have enough information about dengue fever to be able to understand the possible effects it may lead to as well as to how to act immediately when you think you have the said fever.

Another problem withe the people around a person with a dengue is that they do not usually pay attention to the environment they are living in. So instead of curing the said disease, they should have prevented it from happening in the first place. Maybe one example is that parents tend to have less to no time at all in taking proper care of their children and most of them may be due to work or suffering from emotional and psychological stress such as Japanese comfort women.

So here are just must-to-know facts about dengue:

  • Dengue fever is a disease caused by a family of viruses that are transmitted by mosquitoes.
  • Symptoms of dengue fever includes severe joint and muscle pain, swollen lymph nodes, headache, fever, exhaustion, and rash. The presence of fever, rash, and headache is the most common characteristic of a dengue fever.
  • Dengue is prevalent throughout the tropics and subtropics.
  • Because dengue fever is caused by a virus, there is no specific medicine or antibiotic to treat it. For typical dengue fever, treatment is directed toward relief of the symptoms (symptomatic relief).
  • The acute phase of the illness with fever and myalgias lasts about one to two weeks.
  • Dengue hemorrhagic fever (DHF) is a specific syndrome that tends to affect children under 10 years of age. It causes abdominal pain, hemorrhage (bleeding), and circulatory collapse.
  • The prevention of dengue fever requires control or eradication of the mosquitoes carrying the virus that causes dengue.
  • There is currently no vaccine that has been discovered or developed for dengue fever.

What Is A Dengue Fever?

What is dengue fever?

The dengue fever is a disease caused by a family of viruses that are transmitted by mosquitoes. It is an acute illness of sudden onset that usually follows a benign course with symptoms such as headache, fever, exhaustion, severe muscle and joint pain, swollen lymph nodes (lymphadenopathy), and rash. There are also other signs of dengue fever which often concludes to a worse type of dengue. Such symptoms include bleeding of the gums, severe pain behind the eyes, and red palms and soles.

Dengue can affect anyone but tends to be more severe in people with compromised immune systems. Because it is caused by one of five serotypes of virus, it is possible to get dengue fever multiple times. However, an attack of dengue produces immunity for a lifetime to that particular viral serotype to which the patient has experienced before.

Dengue fever is also called “breakbone” or “dandy fever”. Victims of dengue often have contortions due to the intense joint and muscle pain, hence the name breakbone fever. Slaves in the West Indies that acquired dengue were said to have dandy fever due to their postures and gait.

However, dengue hemorrhagic fever is a more severe form of the viral illness. Symptoms of such include headache, fever, rash, and evidence of hemorrhage in the body. Petechiae (small red or purple splotches or blisters under the skin), bleeding in the nose or gums, black stools, or easy bruising are all possible signs of hemorrhage. This form of dengue fever can be life-threatening and can progress to the most severe form of the illness, dengue shock syndrome.
