Wrapping up, in a nutshell,
pertussis is a bacterial infection
caused by the <i>Bordetella pertussis</i> bacteria.
It is a highly contagious bacteria.
It is vaccine-preventable.
In children, they will
receive the DTaP vaccine.
The P is the pertussis coverage.
And in older children and adults,
they will receive the TDaP vaccine.
Again, the P is the pertussis coverage.
There are 3 stages of this.
The catarrhal, which is the
wet phase, first phase,
when patients think they have a cold.
They're spreading pertussis everywhere
because they have a mild illness.
Next, they will go into the second
stage, which is the paroxysmal phase
where they develop the deep whooping cough
that can make them vomit and
take their breath away.
And then the third stage where
they will improve and convalesce.
There's a variable testing window
and a variable treatment window,
so it's really important to have pertussis
on your differential in a high-risk patient.
So macrolides are the preferred treatment.
It is a required public health
notification in all cases of pertussis,
and household contacts also need to
be treated to prevent the spread.
Some patients may require
support in the hospital
and this is typically, the infant population.
And it can also be life-threatening.
