WHAT IS DENGUE HEMORRHAGIC FEVER?
Dengue hemorrhagic fever (DHF) is a severe form of dengue fever, caused by the dengue virus, which is transmitted by Aedes mosquitoes. DHF is characterized by high fever, bleeding, blood plasma leakage, and in severe cases, can lead to dengue shock syndrome (DSS) which is potentially fatal. The symptoms of DHF can include:
- Severe abdominal pain
- Persistent vomiting
- Bleeding from gums or nose
- Blood in vomit or stool
- Difficulty breathing
- Fatigue, restlessness, or irritability
Early diagnosis and proper medical care are crucial to reduce the risk of complications and mortality associated with DHF. Treatment typically involves supportive care to maintain fluid balance, manage pain, and monitor for signs of shock.
IMPORTANCE OF NURSING CARE PLAN IN MANAGING DENGUE
1. Early Detection and Monitoring:
- Regular monitoring of vital signs, fluid intake, and output.
- Observation for warning signs of severe dengue, such as severe abdominal pain, persistent vomiting, bleeding, and sudden drops in platelet count.
2. Hydration Management:
- Ensuring adequate fluid replacement to prevent dehydration and manage plasma leakage.
- Monitoring fluid balance to avoid fluid overload, which can lead to complications like pulmonary edema.
3. Pain and Fever Management:
- Administering antipyretics such as acetaminophen to manage fever and pain.
- Avoiding NSAIDs like aspirin and ibuprofen, which can increase the risk of bleeding.
4. Patient Education:
- Educating patients and caregivers about the importance of hydration, signs of severe dengue, and when to seek immediate medical attention.
- Providing information on preventive measures to avoid mosquito bites and reduce the spread of the virus.
5. Nutritional Support:
- Encouraging small, frequent meals to maintain nutritional status and energy levels.
- Monitoring for signs of gastrointestinal bleeding and providing appropriate dietary modifications.
6. Psychosocial Support:
- Offering emotional support to patients and families to alleviate anxiety and stress related to the illness.
- Ensuring a supportive environment to promote recovery.
7. Coordination of Care:
- Collaborating with other healthcare professionals to ensure comprehensive care.
- Implementing and updating the care plan based on the patient's evolving condition and response to treatment.
PATHOPHYSIOLOGY
The pathophysiology of dengue fever involves a complex interaction between the dengue virus, the host immune response, and various biological processes.
1. Viral Entry and Replication:
- The dengue virus is transmitted to humans through the bite of infected Aedes mosquitoes.
- Once in the bloodstream, the virus targets and infects various cells, particularly dendritic cells, monocytes, and macrophages.
- The virus replicates within these cells, leading to cell death and release of viral particles, which infect new cells.
2. Immune Response:
- The innate immune system responds to the viral infection, leading to the release of cytokines and other inflammatory mediators.
- The adaptive immune response involves the activation of T-cells and B-cells, resulting in the production of antibodies against the virus.
- In some cases, pre-existing antibodies from a previous dengue infection can enhance viral entry into cells, a phenomenon known as antibody-dependent enhancement (ADE), which can lead to more severe disease.
3. Vascular Leakage:
- One of the hallmark features of severe dengue is increased vascular permeability, leading to plasma leakage into the interstitial spaces.
- This is mediated by the release of vasoactive substances, cytokines, and inflammatory mediators, resulting in endothelial cell dysfunction.
- Plasma leakage can lead to hemoconcentration, hypotension, and hypovolemic shock (dengue shock syndrome).
4. Thrombocytopenia and Coagulopathy:
- The dengue virus affects the bone marrow, leading to reduced production of platelets.
- Increased platelet destruction and consumption due to immune-mediated mechanisms and endothelial damage also contribute to thrombocytopenia.
- Coagulopathy, or impaired blood clotting, can occur due to the consumption of clotting factors and platelets, leading to bleeding tendencies.
5. Organ Involvement:
- Severe dengue can affect various organs, leading to complications such as liver dysfunction, myocarditis, encephalopathy, and renal impairment.
- Organ damage is often due to a combination of direct viral effects, immune-mediated injury, and hypoperfusion resulting from plasma leakage and shock.

STATISTICS AND INCIDENCES
1. Global Incidence:
- Dengue is endemic in over 100 countries, with the highest burden in tropical and subtropical regions of Southeast Asia, the Western Pacific, the Americas, Africa, and the Eastern Mediterranean.
- The World Health Organization (WHO) estimates that there are approximately 100-400 million dengue infections annually, of which about 100 million manifest clinically.
2. Mortality:
- Although the overall case fatality rate of dengue fever is relatively low (less than 1% with proper medical care), severe forms of the disease, such as dengue hemorrhagic fever and dengue shock syndrome, can have higher mortality rates if not managed promptly.
- Dengue causes approximately 20,000 deaths annually, primarily in children.
3. Regional Statistics:
- Asia: The region bears about 70% of the global disease burden. Countries like India, Indonesia, Thailand, and the Philippines report a significant number of cases annually.
- Americas: Dengue is a major public health problem, with countries like Brazil, Mexico, and Colombia experiencing large outbreaks. Brazil alone reported over 1.5 million cases in 2019.
- Africa: Although less studied and reported compared to other regions, dengue is increasingly recognized as a significant health issue in countries such as Kenya, Tanzania, and Angola.
4. Trends:
- The incidence of dengue has increased 30-fold over the last 50 years. This rise is attributed to factors such as urbanization, increased travel and trade, climate change, and ineffective mosquito control measures.
- Recent years have seen larger and more frequent outbreaks, with the disease spreading to previously unaffected areas, including parts of Europe and North America.
5. Economic Impact:
- The economic burden of dengue is substantial, with costs related to healthcare, vector control, and lost productivity. In countries where dengue is common, outbreaks can strain healthcare systems and lead to major economic losses.
CAUSES
Dengue fever is caused by the dengue virus, which is transmitted to humans primarily through the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. Here are the primary causes and contributing factors:
1. Dengue Virus:
- The dengue virus belongs to the Flavivirus genus and has four distinct serotypes: DENV-1, DENV-2, DENV-3, and DENV-4.
- Infection with one serotype provides lifelong immunity to that specific serotype but only temporary and partial immunity to the others, making individuals susceptible to multiple infections over their lifetime.
2. Mosquito Transmission:
- The Aedes mosquitoes become infected when they bite a person already infected with the dengue virus.
- Once infected, the mosquitoes can transmit the virus to humans through their bites. The virus is in the mosquito's spit glands, so it spreads easily when the mosquito feeds.
- These mosquitoes typically bite during the day, with peak feeding periods in the early morning and before dusk.
3. Environmental Factors:
- Climate: Warm temperatures and high humidity create ideal breeding conditions for Aedes mosquitoes, facilitating the spread of dengue. Climate change is influencing the distribution and abundance of these vectors.
- Urbanization: Rapid urbanization without adequate infrastructure can lead to increased mosquito breeding sites, such as stagnant water in containers, tires, and other artificial receptacles.
- Water Storage Practices: In areas with inadequate water supply, people often store water in containers, which can become breeding grounds for Aedes mosquitoes if not properly covered or maintained.
4. Human Factors:
- Travel and Migration: More international travel and human migration can bring the virus to new areas and help spread dengue.
- Population Density: High population density in urban areas can facilitate the transmission of the virus from person to person via mosquito vectors.
5. Lack of Effective Mosquito Control:
- Ineffective or inconsistent mosquito control measures can lead to high mosquito populations, increasing the risk of dengue transmission.
- Resistance to insecticides used in vector control programs can also reduce the effectiveness of these interventions.

CLINICAL MANIFESTATIONS
The clinical manifestations of dengue fever can vary widely, ranging from mild symptoms to severe and potentially life-threatening conditions.
1. Febrile Phase (2-7 days)
- High Fever: Sudden onset of high fever (up to 104°F or 40°C).
- Severe Headache: Often located behind the eyes (retro-orbital pain).
- Muscle and Joint Pain: Sometimes referred to as "breakbone fever" due to the severe pain.
- Nausea and Vomiting: Common gastrointestinal symptoms.
- Skin Rash: A maculopapular or petechial rash may appear; it can start on the face and spread to other parts of the body.
- Mild Bleeding: Such as nosebleeds, gum bleeding, or easy bruising.
2. Critical Phase (usually 3-7 days after onset of illness)
- Defervescence: As the fever subsides, symptoms may worsen, marking the beginning of the critical phase.
- Plasma Leakage: Due to increased vascular permeability, leading to hemoconcentration and hypoalbuminemia.
- Shock: Dengue shock syndrome (DSS) can occur due to significant plasma leakage, leading to circulatory failure.
- Severe Bleeding: Particularly in severe cases (dengue hemorrhagic fever), manifesting as gastrointestinal bleeding, hematuria, or bleeding into organs.
- Organ Impairment: Possible involvement of liver, heart, and brain, leading to hepatitis, myocarditis, or encephalopathy.
3. Recovery Phase (48-72 hours after the critical phase)
- Reabsorption of Extravasated Fluid: Fluids that leaked into tissues are reabsorbed into the bloodstream.
- Improvement in Symptoms: Gradual recovery of appetite, stabilization of vital signs, and resolution of gastrointestinal symptoms.
- Skin Rash: May reappear as a "white islands in a sea of red" rash (convalescent rash).
Warning Signs
Recognizing warning signs of severe dengue is crucial for timely intervention:
