Dear Sir,

Ebola virus disease is the new emerging viral infection. It is a disease with severe clinical manifestation and critical care is usually required. The platelet change is a common finding in patients with the Ebola virus disease. However, the change of platelet count during the course of illness has not been well-mentioned. Here, the authors analyzed the available data on platelet count among the hospitalized patients with Ebola virus disease in reported cases. From seven reports on 20 hospitalized patients with Ebola virus disease, all had thrombocytopenia on the hospitalization day.[1],[2],[3],[4],[5],[6],[7] This can confirm the nature of hemorrhagic disease. Further studying on two reports on three patients with available data on platelet change during hospitalization, the lowest peak of decreased platelet level can be detected between day 14 and day 17 of illness (average 16 ± 1.7). After that period, the platelet count slightly increases. Focusing on the lowest platelet count, it was between 10 and 46 × 103/mm 3 (average 22.0 ± 20.8 × 103/mm 3) and the magnitude of decreased platelet count from the first observed platelet count at hospitalization (between 20 and 103 × 103/mm 3; average 51.0 ± 45.3 × 103/mm 3) was between 10 and 57 × 103/mm 3 (average 24.0 ± 29.7 × 103/mm 3). It can be seen that platelet count usually decreases between 2 and 3 weeks of illness and the decrease is about 50% of the level detected on first hospitalization. Nevertheless, the authors’ conclusions from the available data might be partial, biased by the current reported cases as controlled platelet count measurements were not performed. This letter can support a current literature on the disease. Although, at present, the disease might be no longer considered a hemorrhagic fever due to the paucity of hemorrhagic manifestations and the lack of clear correlation to platelet count and bleeding, the present report still present the importance of platelet follow-up in patient care.[8]
