Q

Pertussis: Stages

A

Stage I: Catarrhal (1-2 weeks)

- malaise, conjunctival suffusion, lacrimation, low-grade or no fever

Stage II: Paroxysmal (2-8 weeks, up to 10 weeks)
- coughing spells increase in severity in the first 2 weeks and become violent, frequent, and spasmodic. The coughing spells can remain intense for up to a month before gradually lessening. Episodes of coughing may last several minutes.
- cough may be more prominent at night
- posttussive vomiting is common and sensitive and specific finding pertussis

Stage III: Convalescent (8-12)
- cough subsides and disappears over weeks to months
-The characteristic cough can return up to several months later if another URI is acquired

Q

Pertussis: How to diagnose

A

Cough >3 weeks and patients older than 4 months obtain serology (IgG antibodies, best 2-12 weeks after cough onset)

Q

For latent TB infection
-Isoniazid (9 months, used for HIV, child 2-11 years, pregnant pts)
