What is Dengue Fever Dengue Fever is an illness caused by infection with a virus transmitted by the Aedes mosquito.  Has a sudden onset that usually follows a benign course with fever, headache, exhaustion, rashes, and severe muscle pain, frequently accompanied by sore throat, dizziness, loss of appetite, vomiting, and diarrhea. It is caused by a bite of a striped Aedes aegypti mosquito which has previously bitten an infected person.

NAME : AEDES AEGYPTI Age: 14 to 21 days Place of Birth : Clean stagnant Water Gender : Female Address : Closets and other dark places avenue, Cool and Shaded City Breed: Any water-catching or storage containers in shaded or sunny places. Spread : I can spread the virus if I bite an infected person, but my partners can’t. Likes in Life : I’m favored of breeding places are- Barrels, drums, jars, pots, buckets, flower vases, plant saucers, tanks, cisterns, bottles, tins, tires, pans, plant saucers and roof gutters, refrigerator drip pans, catch basins, drains, soak-away pits, cement blocks, cemetery urns, plant leaf axils, bamboo stumps, tree cavities and a lot more places where rainwater collects or is stored. Motto in Life:

Do you know…..  Only the female Aedes mosquito feeds on blood. This is because they need the protein found in blood to produce eggs. Male mosquitoes feed only on plant nectar.  On average, a female Aedes mosquito can lay about 300 eggs during her life span of 14 to 21 days.

Life Cycle of the Aedes mosquito 1-2 days Stagnant water Pupae 4-5 days LarvaeEggs 2-3 days

Transmission Mosquito bites and sucks blood containing the virus from an infected person. Virus is carried in its body. And passes the virus to healthy people when it bites them.

3 Classification of Dengue Fever 1.undifferentiated fever, 2.dengue fever, 3.and dengue hemorrhagic fever 4 Category Grade I is the presence only of easy bruising or a positive tourniquet test in someone with fever, Grade II is the presence of spontaneous bleeding into the skin and elsewhere, Grade III is the clinical evidence of shock ( DSS)shock Grade IV is shock so severe that blood pressure and pulse cannot be detected.(DSS)blood pressurepulse

Do you know….?  Dengue Fever (DF) and Dengue Haemorrhagic Fever (DHF) are the most common mosquito-borne viral disease in the world.  It can be fatal.

Principal Signs and Symptoms High fever and at least two of the following:  Severe headache  Severe eye pain (behind eyes)  Joint pain  Muscle and/or bone pain  Rash  Mild bleeding manifestation (e.g., nose or gum bleed, petechiae, or easy bruising)  Low white cell count Watch for warning signs as temperature declines 3 to 7 days after symptoms began.

WARNING SIGNS Severe abdominal pain or persistent vomiting Red spots or patches on the skin Bleeding from nose or gums Vomiting blood Black, tarry stools (feces, excrement) Drowsiness or irritability Pale, cold, or clammy skin Difficulty breathing

PREVENTION How can Dengue be prevented? As there is no drug to cure dengue or vaccine to prevent it, there are two key measures that can be applied to prevent the spread of Dengue. 1.Elimination of mosquitoe breeding places 2.Prevent mosquitoe bites

Cover water containers Septic tanks and soak-away pits Removal of Garbage Biological control Chemical control Elimination of mosquito breeding places

· Mosquito coils and electric vapor mats Mosquito nets Repellents Screens Protection of people sick with dengue Prevent mosquito bites

PROMOTION encourages the observance of the 4S strategy against dengue –  Search and destroy,  Self-protection measures,  Seek early consultation,  Say no to indiscriminate fogging. Cleanliness is still the key to prevent dengue but in the presence of its signs and symptoms, immediately consult a physician for proper care.

AWERENESS  Awareness campaign. Schools & local communities are encouraged to carry out communal cleaning activities. Public awareness campaigns through strategically placed posters & television advertisements are also done.
