Although in recent years pediatricians have turned their attention away from the common infectious diseases of childhood, pertussis is still a significant and dangerous disease, causing more deaths in the first year of life than measles, scarlet fever, diphtheria, and poliomyelitis combined.1,2In 1955, there were 467 deaths due to pertussis reported in 62,786 cases of the disease in the United States.2With the reduction of the danger of secondary bacterial complications through the use of appropriate antibiotics, the mortality rate has been reduced markedly. The symptomatology of pertussis has also been altered significantly by the advent of improved symptomatic care, chemotherapy, and mass immunization.
