Results: A total of 156 patients including 67 (42.9%) male and 89 (57.1%) female with the mean age of 15.8±1.9 enrolled in this study who had history of more than two weeks cough. Among the cases 137 (87.8%) patients had paroxysmal cough with an average of 6.9 days. Seven cases (7.8%) had positive cultures for pertussis of whom four aged under two months of old and three were older than two months of old. There was no significant difference in clinical manifestations of the two groups (less and more than two months).
