Increase In Dengue Fever

Despite a slight decrease in the first five months of 2018, the onset of the rainy season has seen an increase in Dengue Fever cases in some areas of the Philippines.

Causes of Dengue Fever

The virus is transmitted by the bite of infected Aedes aegypti and Aedes albopictus female mosquitoes.
They feed both indoors and outdoors, during the daytime (from dawn to dusk).

Pathology

The virus has four major variants, if you are infected with the same Dengue virus serotype you become immune to future infections. However, if you are infected subsequently with a different serotype, immunity wanes over time which increases the risk of developing Dengue Hemorrhagic Fever.

Stages Of The Disease

There three stages of the disease in order of less severe to most, these are progressive, not all those infected go through all stages:

  • The typical uncomplicated dengue fever.
  • Dengue Hemorrhagic Fever (DHS). A serious illness
  • Dengue shock syndrome (DSS). Often fatal

Most Vulnerable

The young and other new arrivals are most suspect to infection, the reason we are featuring this now.
While there is a preventative vaccine. This has become controversial largely because of political influences.
There is no known cure once you contract the disease. The best that medicine can offer is treatments for symptoms.

Symptoms By Stage

In some cases, Dengue infection is asymptomatic – persons do not exhibit symptoms.
Those with symptoms get ill between 4 to 7 days after the bite. They can exhibit some or all of these symptoms:

  • Sudden high fever coming in separate waves
  • Pain behind the eyes
  • Muscle, joint, and bone pain
  • Severe headache
  • Skin rash with red spots.

This can progress to Dengue Hemorrhagic Fever (DHS). This usually requires hospitalisation, symptoms are:

  • Severe abdominal pain
  • Vomiting
  • Diarrhea
  • Convulsions
  • Bruising
  • Uncontrolled bleeding.
  • High fever that can last from 2 to 7 days.

Untreated cases and cases in persons with poor immune systems, can lead to Dengue shock syndrome (DSS). Other infections and indivual complications can lead to:

  • Circulatory system failure.
  • System shock and shutdown.

Preventative Measures

The best way to combat the increase in Dengue Fever is by prevention,The following is the governments strategy implented through the DOH 4S Kontra Dengue:

  • Search and destroy breeding places of mosquitoes. Empty any receptacle that collects stagnant water. Cover containers used for household water.
  • Secure Self Protection. Use a repellent containing 20%-30% DEET or 20% Picaridin on exposed skin. Re-apply according to manufacturer’s direction
  • Seek early consultation.
  • Support fogging/ spraying only in hotspot areas where an increase in cases is registered for two consecutive weeks to prevent impending outbreak.

Additional Preventative Measures.

  • Watch where children and babies are playing they find damp, wwet or dark places that we would overlook.
  • Ensure all netting and screens have no holes and screens are tight fitting.
  • Wear neutral-coloured (beige, light grey) clothing.
  • If possible, wear long-sleeved, breathable garments.
  • If available, pre-soak or spray outer layer clothing and gear with permethrin.
