Title: PERTUSSIS

PERTUSSIS
  • By Erin Dempsey

What is Pertussis?
  • Highly contagious bacterial disease of the
    respiratory tract.
  • Its characterized by severe coughing spells that
    ends in a whooping sound.
  • This disease can be spread from person to person.
  • This can be spread when the person infected
    sneezed, coughs, or laughs.

  • Whooping cough is caused by a bacterium called
    Bortadella pertussis. When inhaled, the bacterium
    attaches itself to cilia in the respiratory
    (breathing) tract. Cilia are tiny, hair-like
    projections on cells that beat back and forth
    constantly. This motion helps clear the
    respiratory system of bacteria, viruses, dead
    cells, and other material.
  • Bortadella pertussis interferes with the motion
    of cilia. The materials normally cleared away by
    cilia become lodged in the respiratory system and
    the cough that results is the body's way of
    attempting to rid the respiratory system of these
    materials.

    over the world.

U.S. Total 25,616 in 2005.

Possible Complications
  • Pneumonia
  • Seizure disorder (permanent)
  • Nose bleeds
  • Ear infections
  • Brain damage from lack of oxygen
  • Bleeding in the brain (cerebral hemorrhage)
  • Slowed or stopped breathing (apnea)
  • Death

9
Treatment and PreventionVaccines
  • DTaP (diphtheria, tetanus, acellular pertussis)
  • Routinely given in five does before the child
    turns six.
  • Tdap
