Dengue hemorrhagic fever (DHF) is a severe and potentially life-threatening condition that can occur as a complication of dengue virus infection. While dengue infection itself can cause symptoms such as high fever, severe headaches, joint and muscle pain, and rash, DHF takes a more dangerous turn.
DHF is caused by the same dengue virus transmitted through the bite of infected Aedes mosquitoes, commonly found in tropical and subtropical regions. To shed light on the causes, seriousness, and cure of DHF, we spoke with Dr. Monalisa Sahu, Consultant in Infectious Diseases at Yashoda Hospitals, Hyderabad.
Causes of Dengue Hemorrhagic Fever According to Dr. Sahu, “DHF is a complication of dengue that some patients develop. It is a severe and sometimes fatal form of the disease.” She explained that around the time when dengue fever subsides, usually three to seven days after symptom onset, some patients may develop warning signs of severe disease.
These warning signs include:
- Severe abdominal pain
- Persistent vomiting
- Significant change in temperature ranging from fever to hypothermia
- Altered mental status (irritability, confusion, or obtundation)
Some patients may also develop early signs of shock, including restlessness, cold clammy skin, rapid weak pulse, and low blood pressure, known as dengue shock syndrome. Dr. Sahu advised patients with dengue fever and these symptoms to return to the hospital for further evaluation and care.
Severity of Dengue Hemorrhagic Fever Severe DHF can manifest with mucosal bleeding and plasma leakages, such as ascites and pleural effusion. Dr. Sahu mentioned that a systolic blood pressure of less than 90 mmHg is associated with higher mortality. Altered consciousness and an insatiable pulse rate are also associated with severe outcomes of DHF. Patients with DHF may also experience multiorgan dysfunction.
Can Dengue Hemorrhagic Fever Be Cured? Early identification of this complication and timely management can significantly decrease the risk of death. Dr. Sahu emphasized the importance of closely monitoring the patient’s vital signs, including heart rate, skin color, temperature, peripheral pulses, and blood pressure. It is also crucial to look for any evidence of bleeding on the skin and signs of increased fluid accumulation in the body.
Dengue hemorrhagic fever is a serious condition that requires prompt medical attention. If you or someone you know experiences dengue symptoms and the warning signs mentioned above, it is essential to seek immediate medical care. Early diagnosis and appropriate management can improve the chances of a favorable outcome.
Remember, prevention is key when it comes to dengue. Taking measures to control mosquito breeding, practicing personal protection against mosquito bites, and promoting awareness about dengue prevention are vital in reducing the risk of infection. Stay vigilant and prioritize your health and well-being, especially during times when dengue is prevalent.
