Disability-adjusted life year for pertussis per 100,000 inhabitants as of 2004. While most healthy older children and adults fully recover, infection in newborns is particularly severe. Pertussis is fatal in an estimated 0.5% of US infants under one year of age. First-year infants are also more likely to develop complications, such as: apneas (31%), pneumonia (12%), seizures (0.6%) and encephalopathy (0.15%). This may be due to the ability of the bacterium to suppress the immune system.
