Spontaneous platelet recovery time in primary and secondary dengue infection in a tertiary care hospital.

enrolled. Serology was performed using rapid immunochromatographic assay and enzyme-linked immunosorbent assay with differential detection of immunoglobulin M and G. Spontaneous platelet recovery time (days) in both primary and secondary dengue infection was recorded. SPSS 20 was used for statistical analysis. Result: Of the total 138, patients, 38(27.5%) had primary infection and 100(72.5%) had secondary infection. Maleto-female ratio was 2.3:1. Among primary and secondary infections, platelet count on presentation was not significantly different (p 50,000/mm3 within 2 days, and 62(57.4%) rose to >50,000 in 3-5 days. . In primary and secondary dengue infections, no statistically significant difference was observed in spontaneous platelet recovery time (-=0.87). Conclusion: Platelet count at presentation and spontaneous platelet recovery time do not significantly differ in
