Pertussis (Whooping
Cough) Pertussis, or whooping cough, is a
highly contagious disease involving the respiratory tract.
It is caused by a bacterium that is found in the mouth, nose
and throat of an infected person and is spread by direct
contact with the discharges from the nose and throat of an
infected individual. The incubation period is usually five
to 10 days but may be as long as 21 days. Pertussis can
occur at any age, although most of the reported cases occur
in children under five year. Fifty percent (50%) of reported
cases are in children under one year of age. Pertussis begins as a mild upper
respiratory infection. Initially, symptoms resemble those of
a common cold, including sneezing, runny nose, low-grade
fever and a mild cough. Within two weeks, the cough becomes
more severe and is characterized by episodes of numerous
rapid coughs followed by a crowing or high-pitched whoop. A
thick, clear mucous may be discharged. These episodes may
recur for one to two months, and are more frequent at night.
Complications of pertussis may include pneumonia, middle ear
infection, loss of appetite, dehydration, seizures, brain
disorders, apneic episodes (brief cessation of breathing),
and death. The vaccine for Pertussis is usually
given in combination with diphtheria and tetanus.
Immunization authorities recommend that DTP (diphtheria,
tetanus, pertussis) vaccine be given at two, four, six and
12-15 months of age and between four and six years of
age. COMMON
