What is Dengue? 

Dengue is a mosquito-borne (Aedes aegypti) infection that in recent decades has become a major international public health concern. Dengue is found in tropical and subtropical regions around the world, predominantly in urban and semiurban areas. Dengue hemorrhagic fever (DHF), a potentially lethal complication, was first recognized in the 1950s during dengue epidemics in the Philippines and Thailand. Today DHF affects most Asian countries and has become a leading

Symptoms of DHF 

     



Dengue fever may be confused with other infectious diseases such as influenza or malaria. Symptoms may include: sudden onset, high fever severe headaches joint and muscle pain nausea vomiting rash that appears three to four days after the onset of fever The illness may last up to 10 days, with recovery often taking two to four weeks.

System affected by dengue 



The circulatory system composed of the heart and blood vessels that moves blood in the entire body is the one affected by dengue. During dengue hemorrhagic fever, the most serious form of the disease, this is characterized by high fever, serious hemorrhage, pneumonia, which may lead to shock (a serious condition in which blood pressure is very low and not enough blood flows to the body’s organs and tissues). Untreated, shock may result to death.

Pathophysiology of Dengue Fever    





 

bite of a virus carrying Aedes mosquito mosquito injects fluids into victim’s skin virus enters blood stream infect cells and generate cellular response initiates immune response (stimulate release of cytokines) cytokines destroys cell membrane and cell walls (viral antigens found in monocytes) fluid shift symptoms manifest itself

If not treated immediately - circulatory collapse then, - shock which lead to death

Diagnostic Evaluation 

History and physical exam



Complete Blood Count (CBC)



Serology



Medical treatment    





Immediate hospitalization IVF Paracetamol to combat fever Cefuroxime (antibiotic) inhibits synthesis of bacterial cell wall, causing cell death. Metronodazole (antibiotic) inhibits DNA synthesis in specific anaerobes, causing cell death. Hydrocortizone (hormone) corticosteroid, short acting – anti-

Nursing Care Management

Monitored vital signs  Continued medications  Watch out for persistence of vomiting  Monitored progress/improvement CBC  Advised to avoid dark color foods  Advised to increase oral body fluid intake 
