Prevalence

Cow’s milk is one of an infant’s first foods.  An allergic reaction can result from either ingestion of formula, or from cow's milk transmitted from the maternal diet into breast milk.1,2  Unsurprisingly, cow’s milk allergy is the most common food allergy in childhood.3  It affects between 2-7.5% of infants.4 

If left unmanaged, most children will outgrow cow’s milk allergy around 3-5 years old on average.3,5,6 
Recent studies suggest a trend towards increasing persistence of cow’s milk allergy in older children.3,6  
The sooner children can consume cow’s milk again, the sooner families can get back to normal life.  


The allergic march

Allergy to cow’s milk protein is usually the first clinical sign of the allergic march – a sequential onset of allergies that can sometimes occur with age.7  This means that infants with cow’s milk allergy have a higher than average risk of developing asthma, eczema and other food allergies.6  The risk of continuation along the allergic march may increase with longer duration of cow’s milk allergy.6,7


Prevalence of allergic manifestations by age - the allergic march

The allergic march starts with sensitisation to food allergens, which affect the skin and GI tract.  Sensitisation to food allergens then switches to sensitisation to aeroallergens, which affect the upper and lower respiratory tract.
