Pertussis in Massachusetts, 1981-1991: Incidence, Serologic Diagnosis, and Vaccine Effectiveness

Abstract: Massachusetts provides diphtheria-tetanus toxoid-pertussis (DTP) vaccine, and since 1980 has monitored pertussis with a statewide diagnostic service. The incidence of bacteriologically confirmed pertussis was 104.5 per 100,000 person-years in 1-month-old infants and declined progressively thereafter. Infants < 6 months old experienced disproportionate morbidity: 44% of bacteriologically confirmed pertussis, 64% of hospitalizations, and 71% of hospital days. Most children with pertussis had received < 3 DTP dos… Show more

“…A specific medium for the culture of B. pertussis was described in 1906 (63), and the demonstration of serum agglutinating antibody for diagnosis was noted in 1916 (635). In the present era, the extensive acellular pertussis vaccine efficacy trials and other epidemiological studies have made it possible to evaluate multiple methods for the laboratory diagnosis of B. pertussis infections (229,293,310,315,317,337,493,536,693,719,722,740,781). Common laboratory diagnostic methods currently include culture, direct antigen detection (direct fluorescent-antibody [DFA] test) PCR, and serologic demonstration (ELISA with many B. pertussis antigens and agglutination) by measuring rises in titer or high single serum values.…”

“…However, for those not recently immunized, this problem can be circumvented by using single-serum ELISA. Specifically, patients with illness will have ELISA titers that are significantly higher than GMT, of sera from well controls (493,550).…”

“…[21][22][23] In the United States, there have been reports of pertussis among adolescents and adults. 24,25 In India, there are no reports of pertussis in adults yet but chances are that these cases are not detected and the susceptibility is also not known.…”
