Dengue fever is a mosquito-borne viral infection that can cause severe illness. One of the characteristic effects of dengue virus is its impact on blood cells, particularly platelets (thrombocytes). Dengue infection often leads to a significant decrease in platelet count (thrombocytopenia), which can increase the risk of bleeding.

Dengue virus significantly reduces the number of platelets in the blood.

While dengue can affect white blood cell counts (often causing a decrease in lymphocytes and neutrophils), the reduction in platelets is a hallmark of the disease and a critical factor in assessing the severity and managing potential complications like dengue hemorrhagic fever. Monocytes and eosinophils are types of white blood cells, and while their counts can fluctuate during infection, the primary clinically significant reduction targeted by the question is typically platelets.
