Since 1996, south-eastern Australia has been experiencing a pertussis
epidemic which has resulted in the deaths of several infants, includin
g four from NSW in the 12 months to July 1997. All were less than six
weeks of age and died from overwhelming cardiovascular compromise desp
ite intensive care support. This excessive infant mortality from a pre
ventable disease demonstrates the need for better pertussis immunity i
n the community and for erythromycin treatment of all suspected cases
and family contacts, especially infants.
