  1. Demographic and hematological status of patients from two groups based on serological outcomes in Dengue virus testing (DENV+ N = 322, DENV- N = 134). Gender (SEX), age (AGE, in years), leukocyte and platelet counts (respectively LEU and PLA, both in Log10 cells/ml), percentage of atypical lymphocytes (AL%) and day of the first attendance at the Marilia Hemocenter (DAY, counted from March 07, 2007, when sampling started) were recorded for 456 patients. All test values are Mann–Whitney U comparisons among groups, except for SEX (X 2 applied to a two-way contingency table). P-values lower than critical (P c = 0.05/6 = 0.0083, considering six contrasts in a Bonferroni correction) were shown in bold
