Stage 1:
Catarrhal
Usually 7-10 d;
range 4-21 d
Characterized by:

• Low-grade fever
• Mild, occasional cough
(gradually becomes more severe)

wks, may persist
for up to 10 wks
Characterized by:
• Paroxysms coughs
• Long aspiratory effort accompanied by "whoop"
• Cyanosis
• Vomiting and exhaustion
• Increase frequency during the first 1-2 weeks,
stable for 2-3 weeks, and then gradually decrease.
Stage 3:
Convalescent
Usually 7-10 d;
range 4-21 d
Characterized by:
• Gradual recovery
• Disappear in 2-3 weeks
