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.
