Control of contacts
Erythromycin should not be given if more than 14 days have elapsed since the first contact with the infectious case (doses and duration as for cases). In special circumstances, such as a high risk exposure for an infant contact, antibiotics may be given within 21 days of first contact with an infectious case. Antibiotics rarely prevent secondary transmission and should be limited to household or child care contacts at high risk of severe complications that have had direct contact with an infectious case:
infants <12 months of age regardless of vaccination status
any child aged between 12 and 24 months who has received less than three doses of pertussis vaccine
any women in the last month of pregnancy
any child or adult who attends or works at a child care facility.
