2. Objectives of Presentation Audience will be able to Understand: Definition of Dengue Fever Epidemiology of Dengue Fever Pathophysiology of Dengue Fever Mode of Transmission of Dengue Fever Risk factors of Dengue Fever Clinical Manifestations of Dengue Fever Complications of Dengue Fever Laboratory Diagnosis of Dengue Fever Treatment of Dengue Fever Prevention and Control of Dengue Fever

3. Definition of Dengue Fever Dengue (pronounced DENgee ) fever is  a painful, debilitating mosquito-borne disease caused by any one of four closely related dengue viruses . These viruses are related to the viruses that cause West Nile infection and yellow fever

4. Epidemiology of Dengue Fever More than 50% of the human population lives in dengue endemic areas.  About 50 to 200 million dengue cases  with 500,000 incidences of dengue hemorrhagic fever Over 20,000 deaths are being documented every year around the globe 

5. Pathophysiology of Dengue Fever

6. Mode of Transmission of Dengue Fever

7. Risk factors of Dengue Fever You live or travel in tropical areas. Being in tropical and subtropical areas increases your risk of exposure to the virus that causes dengue fever. You have had dengue fever in the past. Previous infection with a dengue fever virus increases your risk of severe symptoms if you get dengue fever again

8. Clinical Manifestations of Dengue Fever Clinical findings include  nausea, vomiting, rash, aches and pains , a positive tourniquet test, leukopenia , and the following warning signs: abdominal pain or tenderness, persistent vomiting, clinical fluid accumulation, mucosal bleeding, lethargy, restlessness, and liver enlargement.

9. Complications Complications from dengue hemorrhagic fever seizures. brain damage. blood clots. damage to the liver and lungs. heart damage. shock. death.

10. Laboratory Diagnosis of Dengue Fever To detect the presence of the dengue virus in the blood, you need to undergo definitive tests which include  non-structural protein 1 (NS1) test , Immunoglobulin G/ Immunoglobulin M test or a real time polymerase chain reaction (RT-PCR) test.

11. Prevention and Control of Dengue Fever Use insect repellent, wear long-sleeved shirts and long pants , and control mosquitoes inside and outside your home. Each year, an estimated 400 million people are infected with dengue virus through the bites of infected mosquitoes. limiting contact between people and vectors  is the most effective way to prevent dengue infections. Environmental management approaches involve eliminating the container habitats in which Aedes aegypti lay their eggs.
