What is dengue fever

The Flaviviridae (RNA Virus) family is the home of the dengue virus, responsible for the viral infection known as dengue fever. It is transmitted through the bite of infected Aedes mosquitoes, primarily Aedes aegypti. The virus has four distinct serotypes, namely DEN-1, DEN-2, DEN-3, and DEN-4. Dengue fever is characterized by symptoms resembling the flu, including elevated body temperature, intense headaches, joint and muscle discomfort, and a skin rash.

Causes and Transmission

Dengue fever is primarily transmitted through the bite of infected mosquitoes. The Aedes mosquitoes thrive in urban areas and breed in stagnant water. Mosquitoes become carriers of the dengue virus when they bite an infected individual, enabling them to transmit it to others. However, direct transmission of the virus from one person to another is not possible.

Symptoms of dengue fever

The transmission of dengue fever occurs when an individual is bitten by mosquitoes of the Aedes species infected with the dengue virus. This prevalent disease, commonly found in tropical and subtropical regions, affects millions yearly. The symptoms of dengue fever can vary from mild to severe, and it is essential to be aware of the signs to seek prompt medical attention.

Common Symptoms of Dengue Fever

Dengue fever can present with a wide range of symptoms, and the severity of the illness can vary from person to person. It is essential to recognize the signs of dengue fever to ensure timely medical intervention.

Mild Symptoms

  1. Fever: One of the hallmark symptoms of dengue fever is a high-grade fever, often exceeding 101°F (38.3°C). The fever usually lasts for several days.
  2. Headache: Many individuals with dengue fever experience severe headaches, which can be persistent and throbbing.
  3. Muscle and Joint Pain: Dengue fever is often associated with intense muscle and joint pain, making movement uncomfortable.
  4. Nausea and Vomiting: Some people with dengue fever may experience nausea and vomiting, leading to a loss of appetite and dehydration.
  5. Fatigue: Fatigue and weakness are common symptoms during the recovery phase of dengue fever.

Severe Symptoms

While most cases of dengue fever resolve independently with supportive care, some individuals may develop severe symptoms that require immediate medical attention. These severe symptoms may indicate the development of complications.

  1. Severe Abdominal Pain: Intense abdominal pain can occur in severe cases of dengue fever, often indicating potential organ involvement.
  2. Persistent Vomiting: Continuous vomiting is a worrisome symptom and may indicate severe dengue infection.
  3. Bleeding Gums or Nose: A decrease in platelet count associated with dengue fever can lead to bleeding from the gums or nose.
  4. Difficulty in Breathing: Some individuals may experience respiratory distress, including shortness of breath and rapid breathing.
  5. Organ Impairment: Organ failure can occur due to severe dengue fever, impacting vital organs such as the liver, heart, and other bodily systems.

Warning Signs

In certain instances, dengue fever can advance to more critical manifestations, including dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Prompt identification of the warning signs associated with these conditions is vital to ensure timely medical attention.

  • Dengue Hemorrhagic Fever (DHF): Symptoms of DHF include severe abdominal pain, bleeding under the skin, blood in the urine, and easy bruising. DHF is a medical emergency and requires urgent treatment.
  • Dengue Shock Syndrome (DSS): DSS is a severe form of dengue fever characterized by a sudden drop in blood pressure, leading to shock. It is accompanied by cold and clammy skin, weak pulse, and restlessness. DSS is a life-threatening condition and requires immediate medical intervention.

Diagnosis and Testing

An accurate and timely diagnosis of dengue fever is essential for appropriate management. Healthcare providers use various tests to confirm the presence of the dengue virus in a patient’s body. These tests help differentiate dengue fever from similar illnesses and identify the specific serotype.

Blood Tests for Dengue Fever

Blood tests (Dengue NS1 IgG, IgM & CBC- with in 3 days of fever) are the primary method used for diagnosing dengue fever. These tests aid in identifying the existence of the dengue virus or antibodies generated as a response to the infection. Two primary categories of blood tests are employed for this purpose:

  1. Serological Tests: Serological tests detect the presence of dengue-specific antibodies in the blood. The two common types of serological tests are the IgM antibody test and the IgG antibody test.
  2. Molecular Tests: Molecular tests, including the polymerase chain reaction (PCR), are utilized to identify the genetic material of the dengue virus within the bloodstream. These tests can identify the virus even during the early stages of infection.

Differential Diagnosis

Dengue fever shares symptoms with other viral infections, such as malaria and chikungunya. To differentiate dengue fever from these illnesses, healthcare providers consider the patient’s symptoms, travel history, and the results of diagnostic tests.

Dengue fever treatment

At present, there is no specific established antiviral treatment for dengue fever. The primary focus of treatment revolves around symptom management and delivering necessary supportive care. Here are the critical aspects of dengue fever treatment:

Managing Symptoms

Patients with dengue fever are advised to get plenty of rest and take over-the-counter pain relievers to alleviate fever, headache, and muscle/joint pain. Avoiding medications containing aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) is crucial as they can increase the risk of bleeding.

Fluid Replacement Therapy

Maintaining adequate fluid balance is essential in dengue fever treatment. Patients may experience plasma leakage and dehydration, which can be life-threatening. Oral rehydration solutions and intravenous fluids are administered to prevent dehydration and maintain electrolyte balance.

Diagnosis and Treatment

If you suspect you have dengue fever based on the abovementioned symptoms, it is necessary to get a consultation from a doctor. The diagnosis is usually confirmed through blood tests, which detect the presence of dengue virus or antibodies.

The primary emphasis of treatment lies in providing supportive care to alleviate symptoms and mitigate the risk of complications. It includes bed rest, hydration, and over-the-counter pain relievers to reduce fever and relieve pain.

Prevention and Control Measures

Preventing dengue fever primarily involves controlling mosquito populations and reducing exposure to mosquito bites. To manage the spread out, take some preventive measures that can help:

  • Eliminate stagnant water sources where mosquitoes breed, such as uncovered water containers.
  • Use mosquito repellents that contain DEET & implement them on the external skin.
  • To minimize mosquito bites, wearing protective attire like long-sleeved clothing and pants is advisable.
  • To prevent mosquitoes from entering your home, consider installing screens on windows and doors as a protective measure.
  • Use mosquito nets while sleeping, especially during the daytime when Aedes mosquitoes are active.

Dengue fever vaccine

Vaccines are available to prevent dengue fever. However, the availability and recommendation of vaccines may vary depending on the region. It is essential to consult with healthcare professionals or check the guidelines of the local health authorities regarding dengue vaccination.


Dengue fever is a serious public health concern throughout the world. Recognizing the symptoms of dengue fever is crucial for early diagnosis and appropriate medical care. Typical manifestations of dengue fever include mild symptoms such as fever, headaches, muscle aches, and joint pain. At the same time, more severe indications may encompass intense abdominal pain, bleeding, and compromised organ function. Seeking medical attention if you experience any warning signs or suspect dengue fever is essential. Remember to take preventive measures to reduce the risk of mosquito bites and minimize the spread of the disease.
