Lack of Pertussis Protective Antibodies in Healthcare Providers Taking Care of Neonates and Infants in a Children’s Hospital
Contact tracing and seroepidemiologic studies were done after a premature baby contracted pertussis in a children’s hospital. No infection source was confirmed. Four (3.5%) healthcare providers were positive for anti-pertussis IgM, while only 23% (26/113) were positive for IgG in a following survey. Pertussis vaccination for healthcare providers is needed.
