Dear Sir,

Dengue infection is a common arboviral infection that can result in acute hemorrhagic fever.[1] This infection is common in tropical countries and causes several deaths each year. According to the previous publication,[2] 26.6% of dengue patients had signs of bleeding. Here, the author reported our observation adding to the previous knowledge on dengue hemorrhage. The retrospective review on clinical and laboratory records of dengue 76 patients who visited our medical center during September 2015 was done. Of all 76 dengue cases, at the first visit, 15 cases have signs of bleeding (19.7%). All 15 cases had petichiae (19.7%). Focusing on these 15 cases, there were 3 cases with other signs, 1 case with hematuria (1.3%), 1 with melena (1.3%) and 1 with bleeding per gum (1.3%). Categorized by platelet count, the finding is shown in [Table 1]. It can be seen that the hemorrhage signs can be seen at any levels of platelet count, and there is a relationship between platelet count and hemorrhagic signs. This result confirms the previous observation that the patient could visit the physician at any day of fever and any level of platelet count.[3] Based on the finding, the authors suggest and warn that the practitioner should not rely on only platelet count in judging for management or hospitalization of the patients. The clinical features of the patients should be fully investigated and closely follow-up is needed. In conclusion, this is a letter to the editor dealing with platelet count levels in patients with dengue fever. The author presents data on 76 cases of which 15% hd bleeding symptoms. This type of data confirmed the previous observation that has been presented in the past [2] and add some new information on the relative rate of petichiae only hemorrhagic problem.
