Slow platelet recovery pattern during the 2011 dengue outbreak: a preliminary report.

During the 2011 dengue outbreak, health care providers in Colombo, Sri Lanka noticed a slow rise in platelet counts in patients recovering from dengue fever when compared to the 2010 outbreak. This study was carried out to confirm this observation. The platelet recovery rates of two groups of patients from 2010 and 2011 (n=28 and n=25 respectively) were computed and compared. The platelet recovery rates, of patients from the 2011 outbreak were found to be slower than the platelet recovery rates of patients from the 2010 outbreak (p value=0.0089).
