“From September 1986 through February 1989, we studied UCLA students with cough that lasted 6 days or more . During this 2.5-year period, we found that 26% of the evaluated students had pertussis and that illness was endemic throughout the study period. Similar studies done in adults in the United States, Australia, and Germany have had generally similar findings. Twelve percent to 32% of persons with prolonged cough have been found to have pertussis. In our study, important clinical findings in persons with pertussis were that the median duration of cough illness before seeking care was 21 days, productive cough was rare, the most common clinical diagnosis was bronchitis, and in no case was the diagnosis of pertussis entertained (9).”
