Pertussis, also known as whooping cough, is a very contagious respiratory tract infection caused by a bacterium called Bordetella pertussis. It can infect people of any age, but the infection can be very serious in infants. Complications of a pertussis infection in infants include pneumonia, seizures, brain injury, and death.
