Dengue cases are at a record high, affecting countless individuals each year. Monsoon season serves as the ideal breeding conditions for mosquitoes, resulting in more human-virus interactions. Dengue is a mosquito-borne disease caused by the Dengue Virus (DENV). This viral disease usually manifests as high fever, headaches, tiredness, and vomiting. In advanced cases, Dengue fever can develop into severe Dengue, also known as Dengue Hemorrhagic Fever (DHF) or Dengue Shock Syndrome (DSS).

According to the World Health Organisation (WHO), approximately 390 million Dengue cases are reported each year, of which 500,000 evolve into severe cases. This necessitates increased awareness and effective prevention strategies. This comprehensive guide will explore the critical aspects of severe Dengue, including how to recognise its signs and symptoms, manage its complications, and minimise its impact. Let's get started!

Early Warning Signs of Dengue Fever

Mosquitoes affected by the Dengue Virus cause dengue fever. These mosquitoes can transmit the virus from person to person through their bites. After a person is infected, the virus typically incubates for 4 to 10 days before symptoms appear.

In the early stages of Dengue fever, individuals may experience warning signs such as:

High fever, lasting up to 7-10 days
Intense body pain and headaches
Vomiting and nausea
Tiredness, fatigue, and dizziness
Deep aching pain in the eyes
Gum bleeding or nose bleeding
Rashes (in specific patterns)
Easy bruising

Recognising Severe Dengue Fever

Recognising the difference between the symptoms of Dengue and Severe Dengue is crucial for timely medical attention and treatment. Where Dengue only exhibits flu-like symptoms, Severe Dengue can pose serious health complications that might require hospitalisation.

Signs and symptoms of Severe Dengue include:

Persistent high fever accompanied by a sudden drop in temperatures. It lasts beyond the typical period of Dengue fever and is observed in temperature patterns.

Increased bleeding instances include gum bleeds, easy bruising, nose bleeds, or even Gastrointestinal bleeding, which can easily be spotted via blood in stools or vomit.

Intense abdominal pain which may not be localised.

Fluid leakage into the abdominal cavity or pleural space, resulting in symptoms such as abdominal or chest discomfort.

Organ dysfunction, including liver, kidney or heart, resulting in jaundice, decreased urine output and deteriorated mental status.

Persistent vomiting that does not resolve with the treatment.

Severe lethargy and tiredness that worsen the patient's overall health.

There are signs of shock indicative of Dengue Shock Syndrome (DSS), including low blood pressure, rapid pulse rate, and sometimes cold and clammy hands.

These are life-threatening symptoms, demanding immediate medical attention from the experts to prevent complications.

Diagnosis of Severe Dengue

Diagnosing Severe Dengue requires a comprehensive assessment by the experts due to its complex symptoms, which mimic other medical conditions.

1. Clinical Assessments

The experts start by asking about the detailed medical history of the patient and their recent encounters with mosquito bites or symptoms like high fever, abdominal pain, bleeding, or organ dysfunction.

2. Laboratory Tests

Following the clinical assessments, patients undergo laboratory tests, including:

Blood Test- CBC (Complete Blood Count) is used to detect thrombocytopenia (low platelet count) and Leukopenia (low white blood cell count), which are common in severe Dengue.

Dengue NS1 Antigen Test: It helps detect dengue virus's nonstructural protein 1 (NS1).

Dengue IgM/IgG Antibody Test: It helps confirm the infection by detecting the presence of antibodies produced in response to the Dengue virus.

3. Imaging Studies

Experts use imaging studies, such as chest X-rays or ultrasound, to diagnose severe Dengue by identifying fluid accumulation in the abdominal cavity or pleural space.

Collectively, the doctors can accurately identify the presence of Severe Dengue infection and initiate the treatment plan quickly.

Management of Severe Dengue

Severe Dengue is a life-threatening illness that requires prompt medical help to address its symptoms and mitigate its risks. Management of Severe Dengue include:

Hospitalisation is suggested to monitor and manage a patient's condition closely.

Intravenous fluid therapy (IV) maintains fluid balance and prevents shock from plasma leakage.

Continuous monitoring of health parameters such as blood pressure, pulse, and temperature. In critical cases, patients may require mechanical ventilation.

Blood transfusion to overcome low platelet counts and stabilise the patient.

Pain-relieving medications like Acetaminophen are used to manage fever and pain.

Addressing complications associated with liver and kidney impairment.

Please Note: The use of non-steroidal anti-inflammatory drugs and Aspirin are discouraged as it may cause bleeding.

Preventive Measures for Severe Dengue

Dengue and Severe Dengue can lead to significant discomfort, pain, and prolonged recovery periods. Effective prevention against Severe Dengue requires: Minimum mosquito exposure.

Wearing covered clothing, preferably light colours.

Use of mosquito repellents or nets to add a layer of protection.

Encouraging clean, dry, and hygienic surroundings.

Avoid stepping out during peak mosquito activity hours.

Seeking immediate medical help if you encounter symptoms and avoiding delays.

Frequently Asked Questions About Severe Dengue

Q. Is Severe Dengue dangerous?
A. Severe Dengue is a fatal illness and includes complications like organ dysfunction, high fever, bleeding, and episodes of shock.

Q. What is the severe stage of Dengue?
A. A severe stage of Dengue happens when the patient's blood vessels get damaged and leaky, resulting in serious health complications.

Q. Can we survive Severe Dengue?
A. Yes. With timely medical attention, a personalised treatment plan, and comprehensive care, patients can survive Severe Dengue and recover fully.

Q. Which day is most critical for Dengue?
A. The third day after the fever onset is considered the most critical phase for Dengue.
