It’s a viral infection caused by flavivirus and transmitted by aedes mosquito.
Aedes mosquito usually bites during day time and breeds in stagnant water. Since dengue virus has four antigens so there is risk of getting dengue again for maximum 4 times.
Usually it’s a self limiting illness but it may progress to Dengue hemorrhagic fever and Dengue shock syndrome.
Thrombocytopenia is usually seen on 3-4 day of fever and decreasing trend till 6th day and again increases from 7th day.
If there is pain abdomen, breathlessness, bleeding, hypotension or low blood pressure, hospitalization is recommended.
Rule of 20 for Doctors - Rise in hematocrit (pcv) more than 20% and fall by 20% after fluid replenishment, 20 petechiae in tourniquet test, pulse pressure less than 20mm of hg
Treatment remains supportive... paracetamol for fever and plenty of fluids. For inpatients if platelet is less than 10000 platelet transfusion is done. Avoid drugs which may cause thrombocytopenia...
