Pertussis
Diseases caused by pertussis
Respiratory complications, including asphyxia in infants, are most common. Otitis Media (Acute) occurs frequently. Bronchopneumonia (common among older people) may be fatal at any age. Seizures are common among infants but are rare in older children. Hemorrhage into the brain, eyes, skin, and mucous membranes can result from severe paroxysms and consequent anoxia. Cerebral hemorrhage, cerebral edema, and toxic encephalitis may result in spastic paralysis, intellectual disability, or other neurologic disorders. Umbilical hernia and rectal prolapse occasionally occur.
