Dengue Fever

12:07 PM
With the increasing cases of dengue fever here in the Philippines these days, it is just right to inform the public on what they should know about this viral disease.

What is Dengue Fever?

Dengue fever, otherwise known as “breakbone disease,” is an infectious disease caused by dengue virus. It is transmitted through several species of mosquitoes principal of which is the Aedis Aegypti. This type of mosquito can be distinguished by white markings on its legs.

Trivia: Only female mosquitoes bite in order to mature her eggs! They usually bite during dusk and dawn but may still bite at any time of the day. They breed in areas where there is clean stagnant water.

What are the Signs and Symptoms?

Sudden onset of fever is the most common presenting sign of Dengue Fever. However, about 80% of people infected with the virus are asymptomatic. Accompanying symptoms are headache (usually behind the eyes), muscle and joint pains (which is the reason behind the other name, breakbone disease) and a rash. The course of this infection is divided into three phases: febrile, critical and recovery.

Febrile Phase involves high fever that lasts for two to seven days. It is also the stage where a rash may occur. We may do a tourniquet test as a diagnostic procedure to determine if the patient really has dengue or not. It is done by first getting the blood pressure of the patient and dividing the systolic and diastolic BP by 2. The resulting number would be your mark as to how much mmHg you would inflate the BP cuff that you would leave for 5-10minutes. If more than 10-20 petechiae appear per square inch, the test is positive.

Critical phase needs the most attention. It is during this time that fluid may leak out to other parts of the body. It may cause shock and/or hemorrhage. Platelet count should be monitored at this time.

Recovery phase lasts two to three days. Fluids go back to normal stream and the improvement is often striking.

Treatment for Dengue Fever

There is no treatment for this disease as of now. Main focus is prevention of complications. Fluids play a big role in early recovery. Blood transfusion is also done for severe cases.

Preventive Measures

The Department of Health released these 4S in fighting Dengue:

A) Search and Destroy
  • Get rid of bottles, cans and other   containers that could be used   by mosquitoes to breed.
  • Clean your  rain gutter. (alulod)
  • Change the water in your flower vases once a week.
  • Cover drums and other water containers.

B) Self Protection Measures
  • Use mosquito repellant.
  • Wear long sleeves and pants.

C) Seek Early Consultation
  • If you have a fever for two days already and rashes start to appear on your skin, immediately seek medical advice.

D) Say NO to Indiscriminate Fogging
  • Fogging should only be done when there’s Dengue Outbreak.

A vaccine is also currently under testing and is expected to be completed not later than 2014. Let's hope that this experiment would be a success. :)

  10. Mosquitoes bite some people more than others. We don't really understand why, but a recent paper in PLOS One suggests that genes could play a role in the attraction and gets affected by diseases by mosquitoes
