PERTUSSIS
About Your
Diagnosis
Pertussis or “whooping
cough” is a highly contagious bacterial disease usually occurring in
children younger than 4 years. The causative agent is Bordetella
pertussis, which is usually transmitted by aerosol spread and inhalation.
The incubation period is approximately 7–14 days, during which time the
organism invades the upper and lower airways, resulting in increased mucus
secretion.
Cultures of the nasopharynx,
obtained by using a sterile cotton swab, as well as specific antibody testing
are often diagnostic. Certain viral infections
and
tuberculosis can also mimic the
pertussis syndrome.
Living With Your
Diagnosis
There are usually three
stages to the disease. The first stage has a relatively gradual onset and is
associated with sneezing, runny nose, and fatigue, in addition to a hacking
nighttime cough. After about 10–14 days, the cough becomes more frequent
and more intense, followed by the whoop (a hurried, deep inspiration). During
this second stage, lots of thick secretions may be produced, sometimes with
vomiting and gagging. The recovery stage usually begins within 4 weeks, although
recurrence of the coughing episodes may occur for several months in association
with possible upper respiratory tract
infections.
Treatment
The
best treatment is prevention by active immunization. Starting oral antibiotic
therapy during the incubation period, and continuing for 10–14 days may
abort the infection. Isolation of affected individuals for at least 4 weeks or
until symptoms have subsided is advised, although the use of antibiotic therapy
may be helpful in diminishing infectivity to others. Hospitalization is
recommended for seriously ill infants, in addition to use of small frequent
meals and fluid replacement. Supplemental oxygen may be required, as well as
close monitoring and aspiration precautions. Pertussis may be very serious in
children younger than 2 years, with a mortality rate of approximately 1% to 2%
in children younger than 1 year. Most frequent complications include
bronchopneumonia, collapsed lung, convulsions, and hemorrhage. Ear infections
are also common and may require further antibiotic
therapy.
The
DOs
Pertussis immunization has reduced
the problems of this illness. Respiratory isolation and completion of antibiotic
therapy as advised by your doctor is important. Careful hand washing and close
attention to nutritional needs, especially fluid intake when vomiting occurs,
are very important.
The
DON’Ts
Don’t stop
medications unless advised by your doctor, even if the child is feeling well.
Bed rest is not completely necessary for older children with mild disease. Do
not force children to eat large quantities of food because this may only
aggravate gagging and vomiting during coughing spells. Suction of excess mucus
from the throat may be necessary. A darkened, quiet room with little disturbance
may also help reduce the frequency and severity of the coughing or choking
spells.
When to Call Your
Doctor
Contact your doctor if your
child comes into contact with another child who has had a recent diagnosis of
whooping cough. For a child with pertussis, the caregiver should be prepared to
closely monitor the child, as well as to follow respiratory isolation
procedures. Pertussis is a serious illness and may be fatal, especially in young
children.
