How is pertussis spread?

Pertussis is spread when a person with pertussis coughs, sneezes or talks.  People treated with antibiotics can spread pertussis until they have been on antibiotics for five days.  Unimmunized children (children who have not had their shots) and children who have not had all of their shots are more likely to have serious illness of pertussis.  Protection from the vaccine (shot) lasts for five to 10 years.  People who have had the vaccine are able to get a milder case of pertussis.
