Pertussis is rare in human immunodeficiency virus disease.
Many adults are susceptible to pertussis, and Bordetella pertussis has been isolated from five patients with HIV disease. The prevalence of B. pertussis in 60 HIV-infected adults with nasopharyngeal (NP) swab cultures were studied and questionnaires were used that assessed HIV-related risk behaviors and disease status, immunization history, and symptoms of respiratory disease. Although 72% had cough and 33% had cough for > 14 days, no nasopharyngeal (NP) swab cultures were positive for Bordetella species. Of the 44 (73%) patients who had follow-up NP swab cultures at 6 months, all were still negative. On the basis of these data from our HIV-infected population, the estimated population prevalence of pertussis is zero, with an upper 95% confidence limit of 0.00065, or fewer than 6.5 cases of pertussis per 10,000 HIV-infected adults. Given this low prevalence, HIV-infected patients with respiratory symptoms do not appear to be a reservoir for B. pertussis in the community.
