Dengue Fever

Dengue Fever

Primary vs Secondary Dengue

Primary Dengue infection occurs when a person is infected with the dengue virus for the first time, usually causing classical or mild dengue symptoms.
Secondary Dengue happens when the person is infected again with a different dengue virus strain, and it carries a higher risk of complications.
In secondary infection, the immune response may trigger severe plasma leakage, bleeding tendencies, or shock (Severe Dengue).
Primary Dengue is generally milder, whereas Secondary Dengue can rapidly progress to life-threatening stages.
Early recognition, close monitoring, hydration, and timely medical care are crucial for preventing complications in both conditions.

Dengue Fever

Dengue Shock Syndrome

Dengue Shock Syndrome is the most critical and life-threatening stage of severe dengue.
It occurs due to massive plasma leakage leading to dangerously low blood pressure and reduced organ perfusion.
Patients may show cold clammy skin, rapid weak pulse, severe abdominal pain, restlessness, and reduced urine output.
This condition usually appears during the critical phase when fever declines and requires urgent medical care.
Immediate hospitalization, IV fluids, intensive monitoring, and ICU support are crucial to prevent organ failure and death.

Severe Dengue / Dengue Hemorrhagic Fever

Severe Dengue, also known as Dengue Hemorrhagic Fever, is a life-threatening complication of dengue infection.
It is characterized by severe plasma leakage, sudden drop in platelet count, internal bleeding, and risk of shock.
Patients may experience severe abdominal pain, persistent vomiting, bleeding, breathing difficulty, and extreme weakness.
This stage usually occurs during the critical phase when fever begins to subside.
Immediate hospitalization, close monitoring, IV fluids, and intensive medical care are essential to save life.

Dengue Fever

Dengue with Warning Signs

Dengue with Warning Signs:
Dengue with Warning Signs is a more serious stage of dengue where symptoms indicate risk of complications.
Patients may develop persistent vomiting, severe abdominal pain, bleeding from gums or nose, and extreme weakness.
Other warning signs include rapid drop in platelets, swollen liver, difficulty breathing, and sudden restlessness.
This condition usually appears when fever starts to decrease (critical phase).
Immediate medical attention, hospitalization, monitoring of platelets, and proper supportive care are essential for safety.

Dengue Fever

Simple / Classical Dengue Fever

Simple or Classical Dengue Fever is the milder and most common form of dengue infection caused by the dengue virus.
It presents with sudden high fever, severe headache, eye pain, body aches, joint pain, weakness, and sometimes mild rash.
Unlike severe dengue, bleeding or shock is usually not present in classical dengue.
Platelet count may fall slightly, but most patients recover with proper hydration and symptomatic treatment.
Rest, plenty of fluids, fever management, and regular medical check-ups help in smooth recovery.

Dengue Fever

Dengue Fever

Dengue Fever is a viral infection transmitted by the Aedes mosquito, commonly seen in tropical and subtropical regions.
It causes sudden high fever, severe headache, body pain, joint pain, weakness, and sometimes rash.
In severe cases, it may progress to Dengue Hemorrhagic Fever with bleeding, low platelets, and risk of shock.
Early diagnosis, hydration, fever control, and medical monitoring are important for recovery.
Prevention focuses on mosquito control, avoiding mosquito bites, and maintaining a clean environment to stop breeding.
