Dengue virus can cause low platelet count through multiple mechanisms including interfering with platelet production, infecting endothelial cells, and binding with platelets.
Dengue-induced thrombocytopenia is multifactorial. Mechanisms include suppression of bone marrow (statement 1), direct or indirect damage to endothelial cells leading to increased platelet consumption (statement 2), immunological destruction of platelets through antibody cross-reaction or binding of viral/immune complexes to platelets leading to their removal (statement 3). Accumulation of platelets in the intestine (statement 4) is not a known primary mechanism of dengue-induced thrombocytopenia.
Thrombocytopenia is a common manifestation of dengue fever and a significant risk factor for hemorrhagic complications, especially in severe dengue.
