Helpful facts about pertussis (whooping cough).
Pertussis, or whooping cough, is a communicable respiratory disease which can cause severe illness, complications and even death, particularly in infants. Neither infection nor vaccination confer lifelong immunity. Adolescents and adults with mild or atypical disease can transmit pertussis to infants, young children, and other susceptible persons.
With the continuing resurgence of pertussis, health care professionals will see more patients with suspected pertussis. Polymerase Chain Reaction is an important tool for timely diagnosis of pertussis and is increasingly available to clinicians. This molecular technique is used to detect DNA sequences of the Bordetella pertussis bacterium and unlike culture, does not require live bacteria present in the specimen.
