dengue hemorrhagic fever (DHF)

Dengue hemorrhagic fever (DHF) is a severe complication of dengue infection caused by the dengue virus, transmitted through mosquito bites. It involves increased blood vessel permeability, leading to bleeding, low platelet count, and plasma leakage into tissues. Symptoms include high fever, bleeding gums, severe abdominal pain, and fatigue. DHF can cause shock and organ damage if not treated promptly. It is more common in people who have had previous dengue infections and resides mainly in tropical and subtropical regions. Early medical intervention, proper hydration, and supportive care are essential for recovery.
