Symptoms of whooping cough

Whooping cough symptoms unfold in a recognizable sequence, and the age of the patient changes the picture dramatically - infants show the least typical and most dangerous version.

The opening (catarrhal stage, 1-2 weeks). Exactly like a cold: runny nose, sneezing, mild fever, ordinary cough. This is when the infection is most contagious - and least suspected.

The escalation (paroxysmal stage, 1-6 weeks or longer). The cough becomes fits: 5-15 or more rapid, forceful coughs in one breath, the face going red or blue, eyes watering, ending in a long gasping 'whoop' as air rushes in - and frequently ending in vomiting, choking on mucus, or utter exhaustion. Fits come more at night and are triggered by feeding, crying, smoke or dust. Between fits the child can look nearly normal - a feature that fools families into waiting.

The infant version (the dangerous one). Babies under six months may never whoop. Instead: coughing fits that end in a pause in breathing (apnoea), blueness, limpness, poor feeding, or choking. ANY breathing pause, blue spell or limp episode in a young infant is an emergency - 112/108 immediately. Seizures can occur. Fever is often absent, which misleads.

The adult/adolescent version. Often just a prolonged hacking cough for weeks, sometimes with post-cough vomiting or disturbed sleep - no whoop. It is still contagious to the baby in the house.

The recovery (convalescent stage, weeks to months). Fits fade gradually; a new cold can briefly revive them. Total course commonly runs 6-10 weeks - the '100-day cough'.

Ayurvedic view (interpretive): classical observation of paroxysmal cough with vomiting fits the picture within an interpretive framework of limited evidence. The stage-wise and age-wise pattern above drives the urgency decisions.

Remember: cold, then coughing fits with whoop and vomiting for weeks - that is the textbook. In infants: no whoop needed - a breathing pause, blue spell or limpness after coughing is the emergency signal.
