Hi, this is Tom, and in this episode I'm going to be going through

Whooping Cough, and you can find notes at 0.0.0.5.com and in the 0.0 to Finals

pediatrics book, and you can find flashcards and questions at members.0.0.0.com.

So let's jump straight in.

Whoping cough is a respiratory tract infection caused by border teller pertussis,

which is a gram-negative bacterium. It can affect people of all ages.

It causes coughing fits that are so severe that the child cannot inhale between coughs,

and this is what results in the distinctive whooping sound as they forcefully draw air in after they finish coughing.

Portetalopatasis is infectious for three weeks after the onset of the cough, or until 48 hours after starting

antibiotics. Children and pregnant women are vaccinated against pertussis. When the vaccine is given in

pregnancy, the mother's antibodies cross the placenta and they help to protect the newborn after birth.

The vaccine's protection decreases over time.

Let's talk about the presentation.

The approximate timeline for whooping cough and there is significant variation is that the incubation period from when they have

contact with the illness to when they develop symptoms usually lasts around one week.

Then they develop carisal symptoms lasting around a week, for example, blocked and runny nose,

sore throat and a mild dry cough.

Then there's severe paroxysmal coughing which last between one and ten weeks

and recovery can take weeks to months.

These severe coughing attacks occur suddenly and repeatedly with periods of no coughing in between

attacks, and this is known as a paroxysmal cough.

The cough may be more frequent at nighttime.
