Dengue Fever

Dengue Fever

Dengue fever, also known as broken bone fever, is an infectious tropical disease caused by dengue virus. Dengue is the mosquito-borne viral disease that spreads most rapidly in the world. Mosquito-borne disease caused by any of the four closely related dengue viruses (DEN1 to DEN4). These viruses are related to the viruses that cause West Nile infection and yellow fever.



Dengue Fever


Dengue fever is transmitted by the bite of an Aedes mosquito infected with a dengue virus. The mosquito becomes infected when it bites a person with dengue virus in the blood. It cannot be transmitted directly from one person to another.






Symptoms of dengue fever:

Symptoms, which usually begin four to six days after infection and last 1 to 2 weeks, may include

* Sudden and high fever

* Severe headaches

* Pain behind the eyes.

* Intense pain in joints and muscles.

* Nausea
* Vomiting

* Skin rash, which appears three or four days after the onset of fever.

* Mild bleeding (such as nosebleeds, bleeding gums or easy bruising)

Sometimes the symptoms are mild and can be confused with those of the flu or other viral infection.

Younger children and people who have never had the infection tend to have milder cases than older children and adults. However, serious problems can also develop. These include hemorrhagic dengue, a rare complication characterized by high fever, damage to blood vessels, bleeding from the nose and gums, enlarged liver and circulatory system failure. Symptoms can progress to massive bleeding, shock and death. This is called dengue shock syndrome (DSS).

It is believed that people with weakened immune systems, as well as those with a second or subsequent dengue infection, are at an increased risk of developing dengue hemorrhagic fever.










Do you know Dengue Fever:

* Dengue fever and hemorrhagic dengue fever are the most common mosquito-borne viral disease in the world.

* Only the female mosquito feeds on blood. This is because they need the protein found in the blood to produce eggs. Male mosquitoes feed only on plant nectar.

* The mosquito is attracted by body odors, carbon dioxide and heat emitted by animals or humans.

* The female Aedes mosquito looks for suitable places to lay her eggs.

* The Aedeses are day snappers, more active during sunrise and sunset.








To protect against dengue fever:





Eliminate ALL sources of standing water. Deny the Aedes mosquito any chance of breeding.


Common Dengue fever mosquito breeding ground:

Artificial containers (artificial):

* Vases and pot dishes

* Buckets, water storage jars, basins

* Discarded containers

* Drowned roof gutters

* Gully traps

* Unused toilets and cisterns

* Air conditioning tray and dish tray

* Concrete drains








Dengue fever Natural containers:


* Tree holes, bamboo stumps.

* Armpits of the leaves, fallen leaves

* Earth depressions

Potential Breeding Grounds for Dengue Mosquito:



Steps to do for preventive dengue fever:


* Change the water in vases / bowls every two days.

* Remove water from pot dishes every other day.

* Turn over all storage containers.

* Remove blockages and place insecticide on roof gutters at least once a month.
* Check your landscape structures for water retention and mosquito breeding regularly. Remove these structures if possible.

* Seal the entire floor and canyon traps
* Cover all toilet bowls

* Wear shoes, socks, long pants and long-sleeved shirt.
