Abstract
Dengue infection is a major vector-borne disease. The classical form of this infection has an incubation period of 5 to 8 days followed by fever, violent headache, and chills, with rash developing after 3 to 4 days. A summative report on the platelet count and its clinical correlation to duration of fever in 35 Thai children is presented. Most of the subjects visited to the physician with a complaint for fever. Most patients went to see the physician between the 3rd and the 5th day from the onset of fever. There is no significant correlation between platelet count and duration of fever (ANOVA test, p = 0.28). However, there is a trend of increase platelet count in the later days. In addition, an overview on the previous literatures on platelet count and dengue infection is presented.
