Abstract
Introduction: This multi-center, hospital-based observational study determined the seroprevalence of pertussis antibodies amongst healthcare professionals from three different hospitals in Spain to ascertain the health status of professionals attending to susceptible groups who are at risk of contracting and transmitting pertussis.
Methods: Medical professionals from three hospitals in Spain were recruited for this study (NCT01706224). Serum samples from subjects were assessed for anti-pertussis antibodies by ELISA. The percentage of subjects positive for anti-pertussis antibodies were determined by age-strata, gender, vaccination status, professional level (physicians, nurses, ancillary nurses and midwives), hospital department, number of working years, numbers of hours spent with the patient as well as number of children in the household.
Results: Overall, 31.2% of subjects were seropositive; 3.3% of these healthcare professionals had ELISA values indicative of current or recent infection. There were no significant differences in terms of pertussis prevalence with respect to age, gender, hospital department, profession, number of working years and number of hours spent with patients. These levels of seronegativity amongst healthcare workers further strengthen the rationale for vaccination amongst this specific population against pertussis.
