safe platelet count for dengue
Normal platelet count in a micro litre of human blood is 150000 to 450000. Slight decrease in the platelet count does not contribute to the disease but when it is below 50,000 per micro litre, thrombocytopenia occurs. Low platelet count in dengue fever can be very dangerous.The reasons for low platelet count in dengue fever are as follows. Dengue virus, the main cause of dengue fever induces bone marrow suppression.Since bone marrow is the manufacturing centre of blood cells its suppression causes deficiency of blood cells leading to low platelet count.Anaemia and spontaneous severe bleeding are the other resultant factors of bone marrow suppression.his is one of the major causes of low platelet count in dengue fever. Even the antibodies that are produced after infection of dengue virus can contribute in destruction of platelets, thus lowering the platelet count.
